For most travelers, I’d start with the SURE LOCK 3-Digit Cable Locks with Open Alert: the alert helps show whether a lock has been opened, while the cable fits a range of zipper pulls and attachment points. The Forge Open Alert Cable Locks are a strong alternative if you want a two- or four-pack, while Puroma’s 4-Digit Cable Locks suit travelers who prefer more combination options. The main tradeoffs are alert indicators versus simpler designs, cable flexibility versus compact shackle styles, and combination convenience versus keyed access. Pack size matters too: a four-pack can outfit several bags, but may be unnecessary for a single suitcase. Read on for the full breakdown of all 14 TSA-approved luggage locks and how I’d match them to different travel needs.

Key Takeaways
- Open-alert models stand out for status checks: SURE LOCK and several Forge options add an indicator that can show whether a lock was opened, a feature absent from the simpler models in this lineup.
- Forge offers the widest range of configurations: its options include two- and four-packs, cable and non-cable styles, and orange or black finishes, so fit and visibility can matter more than choosing by brand alone.
- Pack size changes the value equation: LUGGEX, GIVERARE, Master Lock, and several Forge or Puroma options come in four-packs, which makes them more suited to multiple bags or shared household travel than to a single suitcase.
- Combination style is a practical dividing line: Puroma’s 4-digit two-pack offers more dial combinations than the 3-digit options, while GIVERARE and Master Lock’s keyed-alike set avoid remembering a separate code.
- These are access-control tools, not theft-proof barriers: a TSA-compatible lock can secure zipper pulls and allow authorized inspection, but buyers should prioritize travel convenience and fit rather than expect it to protect valuables from determined tampering.

More Details on Our Top Picks
SURE LOCK TSA-Approved 3-Digit Combination Cable Luggage Locks with Open Alert Indicator, 2-Pack
The SURE LOCK 2-Pack suits travelers who want to know whether TSA opened a bag, not just leave it secured for inspection. Its red open alert indicator provides that signal, while the large dials are easier to read than small combination wheels when lighting is poor. The flexible braided cable also fits a wider range of zipper pulls and case openings than some rigid-shackle locks. Compared with the Forge TSA-Approved Cable Luggage Locks with Open Alert, SURE LOCK emphasizes visible, easy-to-read dials; both offer a two-lock set, a resettable three-digit code, and an inspection alert. The tradeoff is that three digits offer fewer possible combinations than the four-digit Forge model elsewhere in this lineup. The alert reports access after the fact—it does not prevent it—and you must remember your code.
Pros:- Red indicator shows when TSA has opened the lock
- Large dials are designed for easier reading in low light
- Flexible braided steel cable fits varied zipper pulls and case openings
- Two locks are included, with a lifetime warranty for quality defects
Cons:- Three-digit code has fewer possible combinations than the four-digit Forge model
- The user must remember the resettable combination
- The alert shows that an opening occurred but does not stop access
Best for: Travelers who want a two-bag set with a visible TSA inspection alert and dials that are easier to read in dim conditions.
Not ideal for: Buyers seeking a four-digit combination or a lock that prevents authorized inspection or unauthorized access.
- Brand:SURE LOCK
- Model:TSA21105V
- Lock type:Combination cable lock
- Combination:Resettable 3-digit
- TSA approved:Yes
- Open alert:Red indicator shows when TSA has opened the lock
- Materials:Zinc alloy body with braided steel cable
- Pack size and color:2 locks; black
- Warranty:Lifetime warranty for quality defects
Our verdict“Choose SURE LOCK if a visible inspection alert and easy-to-read dials matter more to you than a four-digit code.”
Forge TSA-Approved Cable Luggage Locks with Open Alert, Black, 2 Pack
The Forge 2-Pack stands out for its inspection process: the TSA feature requires agents to relock the lock before removing the inspection key. That gives travelers a useful safeguard against a lock being left open after inspection, alongside an alert that indicates it was opened. Its four-inch cable is flexible enough for standard zipper pulls and hard-case lock holes, making it more adaptable than a rigid-shackle design. Compared with the SURE LOCK TSA-Approved 3-Digit Combination Cable Locks, this Forge set also uses a resettable three-digit code and provides an open alert, but its listing gives a specific cable length and relocking behavior. The cable may not suit every locking point as neatly as a rigid shackle, and three digits provide fewer code combinations than the four-digit Forge model in this roundup.
Pros:- TSA inspection feature requires relocking before the key can be removed
- Open alert indicates that the lock was opened
- Four-inch flexible cable fits standard zipper pulls and hard-case lock holes
- Resettable combination and lifetime guarantee
Cons:- Flexible cable may fit some locking points less securely than a rigid shackle
- Three-digit combination offers fewer possible codes than a four-digit lock
- The listing does not specify the open-alert indicator’s color or visibility
Best for: Travelers securing both soft-sided luggage and hard cases who want an inspection lock designed to be relocked before the TSA key is removed.
Not ideal for: Buyers whose locking points fit a rigid shackle better, or who prefer a four-digit combination.
- Brand:Forge
- Pack size:2 locks
- Lock type:TSA-approved cable combination lock
- Combination:Resettable 3-digit
- Cable length:4 in end to end
- Internal loop length:1.5 in when locked
- Body material and color:Zinc alloy; black
- TSA feature:Open alert; agent must relock after inspection
- Warranty:Lifetime guarantee
Our verdict“Pick this Forge set if post-inspection relocking and cable flexibility matter more than a four-digit code.”
Forge TSA-Approved Luggage Locks with Open Alert, Black, 2-Pack
If you prefer more code combinations than a three-digit lock offers, this Forge two-pack is the lineup’s clear choice: its resettable four-digit combination allows 10,000 possible codes. The TSA008 mechanism also signals an inspection and requires the lock to be relocked before the inspection key can be removed, combining access awareness with a specific relocking step. Its coated steel cable bends around different luggage hardware, while the zinc alloy body keeps the lock’s main shell metal. Compared with the Forge TSA-Approved Cable Luggage Locks with Open Alert, this model adds a fourth digit and states the TSA008 relocking mechanism, but its dials and red indicator are plastic. That’s a worthwhile tradeoff for travelers who prioritize more code options, though it is not the best match if metal controls are a priority.
Pros:- Four-digit combination provides 10,000 possible codes
- TSA008 mechanism alerts when opened and requires relocking before key removal
- Coated steel cable accommodates varied luggage hardware
- Zinc alloy body and lifetime warranty
Cons:- Dials and red indicator are plastic
- A four-digit code may be less convenient to remember than a three-digit code
- The listed 5.44-ounce item weight may be a drawback for travelers minimizing lock weight
Best for: Travelers who want a two-lock cable set with a four-digit resettable combination and a TSA relocking mechanism.
Not ideal for: Buyers who prefer metal dials and indicators, or who want a simple three-digit code to set and remember.
- Brand and model:Forge 23072 (Optimus)
- Quantity:2 locks
- Lock type:Pin tumbler cable lock
- Combination:Resettable 4-digit; 10,000 possible codes
- TSA mechanism:TSA008; open alert and relocking required before inspection-key removal
- Materials:Zinc alloy body; coated steel cable; plastic dials and indicator
- Dimensions:1.2 x 0.6 x 3.4 in
- Item weight:5.44 oz
- Warranty and color:Lifetime; black
Our verdict“Choose this Forge model if you want more combination options and TSA relocking, and are comfortable with plastic dials and indicator.”
Forge TSA-Approved Open Alert Cable Luggage Locks, Orange, 2-Pack
The orange finish gives this Forge two-pack a practical advantage over the black SURE LOCK and Forge sets: the locks are easier to pick out among dark luggage and zipper hardware. That visibility pairs with a TSA008 core designed to require relocking after inspection, plus a resettable three-digit combination. Its four-inch sheathed steel cable fits standard zipper pulls and hard-case lock holes, so it offers more attachment flexibility than a rigid-shackle lock. Compared with the black Forge TSA-Approved Cable Luggage Locks with Open Alert, the main distinction is color; both list a three-digit code, a flexible cable and relocking behavior. The orange finish is less discreet, and the cable may be too thin for some locking needs. This is a visibility-first choice, not a heavy-duty barrier.
Pros:- Orange color makes the locks easier to spot on luggage
- TSA008 core requires relocking after inspection
- Flexible sheathed steel cable fits standard pulls and hard-case lock holes
- Resettable three-digit combination and lifetime guarantee
Cons:- Cable may be too thin for some locking needs
- Three-digit code offers fewer possible combinations than a four-digit option
- Bright color may not suit travelers who prefer understated luggage accessories
Best for: Travelers who want two TSA-approved locks that are easy to distinguish from black luggage hardware and bags.
Not ideal for: Buyers who want a discreet black lock, a thicker cable, or a four-digit combination.
- Brand:Forge
- Color:Orange
- Pack size:2 locks
- Lock type:3-digit combination cable lock
- Combination:Resettable 3-digit
- Cable length:4 in end to end
- Internal loop length:1.5 in when locked
- Body material and TSA core:Zinc alloy; TSA008
- Warranty:Lifetime guarantee
Our verdict“Choose the orange Forge set if visibility on your luggage matters more than a discreet finish or thicker cable.”
LUGGEX TSA-Approved Cable Luggage Locks, 4-Pack
The LUGGEX 4-Pack is the practical pick when one or two locks will not cover the trip: four locks can secure multiple suitcases, backpacks, or travel bags. Its high-contrast combination dials support quick reading, while the lightweight ABS body and braided steel cable keep each lock at 33 g. TSA officers can open and relock the locks with a master key, so there is no user key to carry or misplace. Compared with the two-lock SURE LOCK set, LUGGEX gives you more locks and a lighter listed weight per lock, but it does not list an open-alert indicator or combination digit count. The ABS body also differs from the zinc alloy bodies on the Forge options, and these locks are intended as travel deterrents rather than strong barriers.
Pros:- Four locks cover more bags than the two-lock sets
- Lightweight at 33 g per lock
- High-contrast dials are designed for easy reading
- TSA officers can open and relock the locks with a master key
Cons:- No physical user key is included
- ABS body is not zinc alloy like the Forge and SURE LOCK options
- Designed as a travel deterrent, not a strong barrier against determined access
Best for: Families or group travelers who need several lightweight TSA-approved combination locks for multiple bags.
Not ideal for: Travelers who want a clearly specified open alert, a metal lock body, or a physical key option.
- Pack quantity:4 locks
- Lock type:TSA-approved combination cable lock
- Materials:ABS body and braided steel cable
- Size:4 x 1.4 x 0.5 in
- Weight:33 g per lock
- Dials:High-contrast combination dials
- TSA access:TSA officers can open and relock with a master key
- Key included:No
Our verdict“Choose LUGGEX if you need four lightweight TSA-approved locks for several bags and do not need a user key or open-alert indicator.”
Forge TSA-Approved Open Alert Cable Luggage Locks, Black, 4-Pack
I’d choose this set for travelers who want four flexible cable locks and a clear inspection-focused design. The open alert feature is meant to show that a lock was opened, while its relocking design calls for TSA agents to secure it again after inspection. That gives it a more inspection-aware role than the GIVERARE keyed padlocks, which rely on physical keys rather than a combination and cable. The resettable three-digit code avoids carrying keys, and the zinc alloy bodies and braided steel cables suit common luggage and bag closures. The tradeoff is reach: each cable is only 4 inches end to end, with a 1.5-inch internal loop when locked, so it may not fit bulky or unusually placed fastening points. Compared with the Puroma 4-digit cable lock, it also offers fewer code combinations. The lifetime guarantee adds reassurance, but the short cable is the key fit check.
Pros:- Four locks cover multiple bags or cases.
- Flexible braided steel cables fit many standard zipper pulls and hard-case lock holes.
- Resettable combination removes the need to carry keys.
- Open alert design and lifetime guarantee add inspection awareness and warranty backing.
Cons:- The 4-inch cable and 1.5-inch locked loop may not fit larger fastening points.
- Three-digit code has fewer possible combinations than the four-digit Puroma option.
Best for: Travelers securing several bags with standard zipper pulls who want a combination lock and an inspection alert design.
Not ideal for: People locking oversized fastening points or seeking a longer cable, and travelers who prefer a four-digit code.
- Pack size:4 locks
- Lock type:Combination cable lock
- Combination:Resettable 3-digit
- Cable length:4 inches end to end
- Internal loop length:1.5 inches when locked
- Materials:Zinc alloy body and braided steel cable
- Color:Black
- Features:TSA open alert, weather resistant, portable
- Guarantee:Unconditional lifetime guarantee
Our verdict“Choose this Forge set for four standard-size bags when cable flexibility and an inspection alert matter more than longer reach or a four-digit code.”
Forge TSA-Approved Flexible Cable Luggage Locks, 4-Pack
This Forge set suits travelers who want four combination cable locks for ordinary luggage and backpacks, without paying for a different lock style across each bag. Its flexible, sheathed steel cables work with standard zipper pulls and many hard-case lock holes, while the TSA open alert and relocking design address the inspection concern built into this roundup. The Forge Open Alert Cable Locks, Black, 4-Pack offer a very similar cable format, so the choice between them should come down to the specific feature details and listing you need rather than expecting a major difference in everyday fit. Against the Forge Titan 2-Pack, this set gives you twice as many locks and cable flexibility, but the Titan has larger dials and an inspection indicator. Here, the fixed 4-inch cable is the main limitation: it can be too short for wider closures. A three-digit code also offers fewer combinations than Puroma’s four-digit model.
Pros:- Four locks provide coverage for multiple bags.
- Flexible sheathed steel cable accommodates common luggage closures.
- Resettable three-digit codes avoid carrying keys.
- TSA open alert design and unconditional lifetime guarantee.
Cons:- The 4-inch cable may not reach around larger fastening points.
- Three-digit combinations provide fewer possible codes than the Puroma four-digit option.
Best for: Travelers who want one resettable cable-lock style for several suitcases, backpacks, or cases with standard attachment points.
Not ideal for: People with large or awkwardly placed lock points, or buyers who value a stated inspection indicator and larger dials more than a four-lock pack.
- Pack size:4 locks
- Lock type:TSA-approved combination cable lock
- Combination:Resettable 3-digit
- Cable length:4 inches end to end
- Locked internal loop length:1.5 inches
- Body material:Zinc alloy
- Cable material:Braided, sheathed steel
- Lock core:TSA008
- Guarantee:Unconditional lifetime guarantee
Our verdict“Pick this pack for several bags with standard-size attachment points; choose the Forge Titan instead if its larger dials and inspection indicator matter more.”
GIVERARE TSA-Approved Travel Luggage Locks with Keys, 4 Pack, Black
For travelers who prefer a key over remembering a combination, this four-pack gives each lock a keyed padlock format with eight keys included. The hardened steel shackle and brass cylinder offer a different approach from the flexible cables on the Forge four-packs: GIVERARE is a compact choice for compatible zipper pulls and small locking points, while Forge cable locks can accommodate a broader range of attachment shapes. Its lightweight ABS housing and water-resistant design suit travel and outdoor use, but the listed 0.12-inch shackle and compact body make fit worth checking before buying. Compared with the Forge Titan 2-Pack, this set supplies more locks and avoids code-setting, yet gives up combination access and an inspection-alert indicator. Eight keys help distribute spares, though keeping track of them becomes the main ownership burden.
Pros:- Four locks and eight keys allow spares to be shared or stored separately.
- Hardened steel shackle and brass cylinder provide a sturdy keyed construction.
- Compact, lightweight format suits travel and outdoor use.
- TSA-approved design allows inspection and relocking.
Cons:- Physical keys must be carried and kept track of.
- Small shackle may not fit some luggage locking points.
- Unlike the Forge Titan, it has no stated inspection alert indicator.
Best for: Travelers who prefer physical keys, need four compact locks, and can keep spare keys organized among their travel group.
Not ideal for: People who do not want to carry or track keys, or whose luggage has locking points too wide for the small shackle.
- Model:JSTSA815B4
- Pack size:4 locks
- Included keys:8
- Lock type:Keyed padlock
- Materials:Hardened steel, brass, and high-impact ABS
- Shackle diameter:0.12 inches
- Dimensions:1 x 0.52 x 2 inches
- Item weight:9.07 g
- Features:TSA approved, water resistant, cutting resistant
Our verdict“Choose GIVERARE if you want four compact keyed locks and can manage the keys; skip it if combination access or broader cable fit is a priority.”
Forge TSA-Approved Luggage Locks, Black, 2-Pack
I’d rank the Forge Titan for travelers who want to know whether security opened a lock, rather than simply buying the largest multipack. Its inspection alert indicator adds a visible check, and the relock feature is intended to help prevent a bag being left unlocked after inspection. The three-digit code resets, while large, easy-read dials can be more convenient than the smaller controls common on compact locks. Compared with the Forge flexible cable four-pack, the Titan supplies only two locks and uses a steel shackle instead of a cable, so it is less adaptable to unusual fastening points but may suit standard zipper pulls neatly. The Puroma 4-digit cable lock offers more code combinations and cable flexibility; this Forge model counters with its stated alert indicator and TSA008 cylinder. Bag compatibility still depends on the zipper openings, and the listing does not specify weight.
Pros:- Inspection alert indicator shows whether a lock was opened for inspection.
- Relock feature helps reduce the chance of leaving a bag unsecured.
- Large, easy-read dials and resettable combination simplify routine use.
- Compact format fits many standard luggage and bag zippers.
Cons:- Two locks may not cover multiple suitcases or a family’s bags.
- Steel shackle is less adaptable than the cables on the Forge and Puroma cable-lock sets.
- Compatibility can vary by zipper, and weight is not specified.
Best for: Solo travelers or couples who want an inspection-status indicator, readable dials, and locks for standard luggage zippers.
Not ideal for: Families needing four locks, or people whose luggage requires a flexible cable to reach its fastening points.
- Model:Forge Titan 12022
- Pack size:2 locks
- Combination:Resettable 3-digit
- Lock cylinder:TSA008
- Body material:Zinc alloy
- Dimensions:1.24 x 2.45 inches
- Color:Black
- Features:Inspection alert indicator, relock protection, easy-read dials
Our verdict“Choose the Forge Titan for two standard-zipper bags when a visible inspection alert and readable dials matter more than cable versatility.”
Puroma 2-Pack TSA-Approved 4-Digit Cable Luggage Locks
Puroma stands out for travelers who want a cable lock but prefer a four-digit resettable code to the three-digit format on both Forge cable sets. With 10,000 possible combinations and large white numerals on black dials, it gives buyers more code choices and a high-contrast layout that may be easier to read. The flexible steel cable also fits luggage, backpacks, and equipment cases, unlike the Forge Titan’s steel shackle, which is aimed more at standard zipper openings. This is a two-lock set, though, so the Forge four-packs are a better match for families or people securing several bags at once. Puroma lists weather, rust, and corrosion resistance, but does not provide cable length or lock dimensions. That missing sizing information makes fit harder to judge in advance, particularly for wide or oddly positioned lock points.
Pros:- Four-digit resettable combination provides 10,000 possible codes.
- Flexible steel cable suits luggage, backpacks, and equipment cases.
- Large white numerals on black dials improve contrast when setting the code.
- TSA agents can unlock and relock the locks; materials are described as weather, rust, and corrosion resistant.
Cons:- Two locks cover fewer bags than either Forge four-pack.
- Cable length and lock dimensions are not provided, making fit difficult to verify.
- Four-digit entry takes more dialing than the three-digit Forge options.
Best for: Travelers who want a flexible cable lock with a four-digit code for one or two bags, backpacks, or equipment cases.
Not ideal for: Families needing four locks at once, or buyers who need confirmed cable length and lock dimensions before checking compatibility.
- Pack size:2 locks
- Lock type:Mechanical combination lock
- Combination:Resettable 4-digit
- Possible codes:10,000
- Cable:Flexible steel
- Materials:Zinc alloy and steel
- Color:Black
- TSA status:TSA approved
- Additional features:Weather resistant, rust resistant, corrosion resistant
Our verdict“Choose Puroma for a flexible cable and more code combinations across one or two bags, but opt for a Forge four-pack if quantity or listed cable dimensions matter more.”
Forge TSA Approved Luggage Locks with Open Alert Indicator, Black, 4-Pack
I’d choose this Forge set when knowing whether security opened a bag matters as much as locking it. Its red open-alert indicator signals that a lock was inspected, while the Always Relocked feature is designed to prevent a bag being left unsecured after the lock is opened. The zinc alloy body and reinforced TSA008 core give it a sturdier feel than the flexible-cable approach of the Puroma 4-Pack, though the Puroma cables are more adaptable to varied zipper pulls and locker fittings. This set also provides four locks, making it practical for several suitcases. The tradeoffs are its small size, which can be easy to misplace, and a reset process that calls for careful attention to the instructions. I’d pick it for frequent checked-bag travelers who value an inspection signal over cable flexibility.
Pros:- Red indicator shows when a lock has been opened for inspection
- TSA008 reinforced core and zinc alloy body add sturdiness
- Always Relocked feature helps prevent leaving luggage unsecured after inspection
- Four locks cover multiple suitcases or travel bags
Cons:- Compact size can be easy to misplace
- Resetting the combination requires careful adherence to the steps
- Rigid shackle is less adaptable to varied attachment points than the Puroma cable locks
Best for: Frequent travelers who check several bags and want a visible indication that TSA inspection occurred.
Not ideal for: People who often secure wide or awkward zipper pulls, or who prefer a simple, forgiving combination-reset process.
- Brand:Forge
- Quantity:4 locks
- Lock type:TSA-approved combination lock
- Combination:3 digits
- Body material:Zinc alloy
- Shackle material:Steel
- Core:TSA008 reinforced core
- Dimensions:1.24 x 2.45 inches
- Color:Black
Our verdict“Choose this Forge four-pack if inspection awareness and a reinforced lock matter more to you than cable flexibility.”
Master Lock TSA Approved Combination Luggage Lock (Model 4688D)
For a buyer who needs one cable-style lock rather than a matching set, the Master Lock 4688D is a straightforward option. Its vinyl-covered steel cable flexes around zipper pulls and attachment points that a rigid shackle may not fit, and the custom three-digit combination avoids carrying a key. The metal body and stated limited lifetime warranty make it a more traditional, durable-feeling choice than the lightweight plastic-bodied approach described for the Puroma 4-Pack. Unlike the four-lock Forge set, this Master Lock is sold as a single lock and has no open-alert indicator, so it’s less suited to travelers securing several bags or wanting to know whether a lock was opened. The cable coating may wear with heavy use, and assorted colors limit control over its appearance. I’d favor it for a single bag with awkward zipper hardware.
Pros:- Flexible vinyl-covered steel cable fits a range of attachment points
- Resettable three-digit combination means no key to carry
- Metal body and cable construction are suited to baggage handling
- Limited lifetime warranty is specified
Cons:- Sold as a single lock rather than a multi-lock set
- Vinyl cable covering may wear with frequent or heavy use
- Assorted color does not let buyers select a specific color
Best for: Travelers who need one combination lock with a flexible cable for a suitcase or bag with hard-to-fit zipper pulls.
Not ideal for: Families securing several bags, or travelers who want an inspection indicator or a specific lock color.
- Brand:Master Lock
- Model:4688D
- Lock type:Combination lock
- Combination:3 digits
- Body material:Metal
- Cable material:Steel with vinyl covering
- Body width:1-3/16 inches (30 mm)
- Cable length:1-1/2 inches (38 mm)
- Warranty:Limited lifetime
Our verdict“Pick the Master Lock 4688D for one bag with awkward zipper fittings; choose the Forge four-pack if you need multiple locks and an inspection alert.”
Master Lock TSA-Accepted Keyed-Alike Luggage Locks, 4-Pack
This four-pack suits travelers who would rather use a key than remember combinations. One key opens all four locks, so a family or frequent traveler can secure several bags without managing separate codes. Its solid metal body and steel shackle offer a compact, rigid alternative to the flexible cable on the Master Lock 4688D; that cable is easier to loop through unusual fittings, but the 4683Q’s keyed setup is simpler if its shackle fits your zipper pulls. TSA screeners can inspect and relock the bags without damaging the locks. The main compromise is key dependence: lose or forget the keys and access becomes inconvenient. Only two keys come with the set, so sharing locks among several travelers takes some planning. I’d choose it for organized households that can keep a spare key accessible.
Pros:- One key operates all four locks
- Solid metal bodies and steel shackles provide a rigid construction
- TSA-accepted design permits inspection and relocking
- Compact locks suit suitcases, backpacks, and travel bags
Cons:- Opening the locks depends on having a key available
- Only two keys are included for four locks
- Rigid shackle may not fit zipper pulls as readily as the cable on the Master Lock 4688D
Best for: Families or travel groups who want several TSA-accepted locks operated by the same key.
Not ideal for: Travelers who avoid carrying keys, need flexible cable fittings, or want each person to have a dedicated spare key.
- Brand:Master Lock
- Model:4683Q
- Pack size:4 locks
- Keys included:2
- Lock type:Keyed padlock
- Body material:Solid metal
- Shackle material:Steel
- Body width:7/8 inch (22 mm)
- Weight:3.52 oz
Our verdict“Choose this set if you want four compact TSA-accepted locks on one key system and are comfortable keeping the keys secure.”
Puroma 4-Pack TSA-Approved Luggage Locks with Flexible Steel Cable, 3-Digit Combination, Black
The Puroma four-pack is the most adaptable pick here for buyers who want to use the same style of lock on luggage, backpacks, or locker loops. Its flexible steel cables can pass through fittings that may not accept a rigid shackle, while the resettable combination avoids the key-management tradeoff of the Master Lock 4683Q. White numerals on black bodies also make the code easier to read than low-contrast markings, especially when setting a combination in dim conditions. The set is described as lightweight and resistant to weather, rust, and corrosion, which suits varied travel and storage uses. Its three-digit code offers fewer possible combinations than a four-digit option, and the cable is less resistant to heavy cutting tools than a solid shackle. I’d choose it for versatility, not maximum resistance to force.
Pros:- Flexible cables fit a wider range of zipper pulls and loops than rigid shackles
- White numerals contrast with the black lock for easier code reading
- Four combination locks cover multiple bags or storage uses
- Listed as weather, rust, and corrosion resistant
Cons:- Three-digit combination has fewer possible codes than a four-digit lock
- Flexible cable is more vulnerable to heavy-duty cutting tools than a solid shackle
- Does not include the open-alert feature found on the Forge four-pack
Best for: Travelers who want one lightweight four-pack for suitcases, backpacks, gym lockers, and equipment cases.
Not ideal for: Buyers prioritizing resistance to heavy-duty cutting tools or seeking a four-digit combination for more code choices.

Our verdict“Choose the Puroma set for lightweight, flexible fit across different bags and lockers, but skip it if cutting resistance is your priority.”
How We Picked
I compared the 14 options by the features that change day-to-day travel use: whether they have an open-alert indicator, how the cable or shackle is likely to fit common zipper pulls, whether access uses a combination or key, and how many locks come in each pack. I also considered ease of setup, visibility, and whether the listed design is better suited to one case, several bags, or shared travel. A lock’s TSA-compatible design is relevant to inspection access, but it does not make luggage theft-proof, so I treated that claim as a travel-use feature rather than a promise of security.
The ranking favors useful combinations of fit, access feedback, and versatility over pack count alone. SURE LOCK leads as a balanced two-pack with an alert and flexible cable; Forge’s alert models follow for buyers who want comparable feedback in different quantities and finishes. The remaining picks serve narrower priorities—four-lock coverage, keyed access, or a different combination style—so their placement reflects who is most likely to benefit, not a claim that one design suits every suitcase.
Factors to Consider When Choosing Tsaapproved Luggage Locks
Before choosing a lock, I’d match its design to the bags you actually travel with and the way you prefer to manage access. A feature that sounds useful on paper may add little if it does not fit your zipper pulls or if you rarely check the lock after inspection.
Match the locking style to your luggage
Check the shape and size of the zipper pulls, zipper holes, and nearby attachment points before choosing a cable or shackle design. A flexible cable can thread through awkward or paired pulls that a rigid shackle may not accommodate, but a longer cable can also leave more slack. Small zipper holes may rule out some lock designs even when the product is marketed for luggage. If you use a backpack, duffel, or hard-shell case as well as a suitcase, test the intended attachment route on each bag. Avoid assuming that a lock’s broad luggage compatibility means it will fit every zipper. Fit is a better first filter than color or pack size.
Decide whether an open-alert indicator is worth it
An alert indicator can tell you that a lock has been opened since you last checked it, which may be useful after a flight or a checked-bag inspection. It does not explain why the lock was opened, and it does not prevent access by itself. If you choose an alert model, learn how to reset or read the indicator before traveling so you do not mistake its status. Travelers who rarely check their bags may get less practical benefit from this feature than travelers who want a quick post-flight cue. Simpler locks can be easier to understand, while alert versions add a small but specific check. Treat the indicator as information, not proof that your belongings were untouched.
Choose a combination or keyed access based on your habits
Combination locks avoid carrying a small key, but they require you to remember the code and set it correctly before departure. A 4-digit design gives more possible codes than a 3-digit design, though that difference does not make a luggage lock resistant to every attack. Keyed-alike packs can simplify access across several bags, but the key becomes another item to keep track of. Think about who needs to open the bags: a solo traveler may prefer one familiar code, while a family may find a shared key easier to coordinate. Keep the combination or spare key separate from the locked bag. Choose the access method you can manage reliably when tired or in transit.
Buy the number of locks you will actually use
Two-packs suit travelers who secure one suitcase and a second bag, or who want a spare. Four-packs make more sense for families, multi-bag trips, or keeping locks ready for different pieces of luggage. A larger pack is not automatically better value if extra locks will sit unused or if you need only one particular style. Also check whether every lock in a set uses the same access method and whether the set is keyed alike when keys are included. When buying for several people, assign each lock before travel rather than sorting out codes at the airport. Match quantity to the bags you routinely check, not the largest trip you might take someday.
Set realistic expectations about luggage security
A TSA-compatible lock is designed to allow authorized screening access with the appropriate inspection tool, but it cannot guarantee that a bag will avoid inspection or tampering. A lock can help keep zipper pulls together and make casual opening less convenient; it is not a substitute for keeping valuable or sensitive items in carry-on luggage. Do not assume that a sturdy-looking body makes a lock cut-proof, especially if the cable is exposed. For items that would be difficult to replace, use a more suitable travel plan rather than relying on a small luggage lock alone. Buyers should compare ease of use and fit before treating a lock as a security upgrade. That distinction helps prevent paying for features that cannot deliver the protection a traveler expects.
Prioritize visibility only when it helps your routine
A bright finish, such as the orange Forge option, can make a lock easier to spot on a crowded baggage carousel or distinguish from a travel companion’s bag. Black models blend in more quietly and may suit buyers who prefer a low-profile look. Color does not change the lock’s access method or inspection compatibility, so it should be a tie-breaker after fit and usability. If your luggage itself is distinctive, a vivid lock may add little; if you share similar bags, it can help with quick identification. Check that any color preference does not distract from reading the combination dials. Choose visibility for a practical reason, not as a stand-in for security.
Frequently Asked Questions
Does a TSA-approved lock guarantee that my checked bag will not be opened?
No. A TSA-compatible lock is intended to allow authorized inspectors to access a locked bag with the appropriate tool, but it does not prevent inspection. An open-alert model may indicate that the lock has been opened, but it cannot tell you who opened it or what happened inside. I’d treat the lock as a way to keep zipper pulls together and discourage casual access, not as a guarantee against theft. Keep irreplaceable or valuable items with you when possible.
Should I choose a cable lock or a rigid-shackle lock?
Choose based on the openings and attachment points on your luggage. A cable can be easier to thread through paired zipper pulls, narrow loops, or bags with unusual layouts, while a rigid shackle may suit luggage with larger, aligned holes. Cable flexibility can also mean extra slack, so check how closely the lock holds your zipper pulls together. If you want one lock for multiple types of bags, a cable design may be more adaptable. For a single case, a simple fit check may matter more than the lock’s general style.
Is a 4-digit combination lock a better choice than a 3-digit model?
A 4-digit lock offers more possible combinations, but that alone does not make it a high-security device or a guarantee against tampering. The more useful question is whether you can set and remember the code comfortably. A 3-digit design may be simpler to enter, while a 4-digit model such as Puroma’s two-pack may appeal to travelers who prefer the extra code options. Neither format removes the need to keep valuable items out of checked luggage. Pick the style you are least likely to mis-set or forget.
Is a four-pack worthwhile if I usually travel with one suitcase?
Usually, a two-pack is enough for one suitcase plus a second bag or spare. A four-pack makes more sense if you regularly check several bags, travel with family, or want locks ready for different luggage pieces. The lineup includes four-packs with different access styles and features, so quantity should not be the only deciding factor. A larger set can leave you with unused locks if your needs stay limited. Count the bags you routinely secure before choosing the pack size.
Can I use a TSA-compatible lock if I forget the combination or lose the key?
Do not assume that an inspector’s access tool will solve a forgotten combination or lost-key problem; inspection access and owner access are different matters. Before travel, set the combination and confirm that you can open and relock the device, or keep the key somewhere separate from the locked luggage. For a keyed-alike set, remember that one key may operate multiple locks, so losing it can affect the whole set. If you are prone to forgetting codes, a keyed option may suit you better, provided you can keep the key secure. Check the manufacturer’s instructions for recovery steps before relying on any particular model.
Conclusion
For the best overall balance, I’d choose the SURE LOCK 3-Digit Cable Locks with Open Alert: its two-lock format combines flexible attachment with a useful status cue. The best value for outfitting several bags is one of the four-packs, with Forge’s Open Alert Cable Locks offering the stronger feature mix and LUGGEX serving buyers who want a straightforward multi-lock set. For a premium-leaning feature choice, I’d pick a Forge four-pack with an open-alert indicator; the lineup’s evidence points to added feedback and quantity rather than a luxury build claim. Beginners may prefer a simple combination model with a clear setup routine, while travelers who dislike codes can look at GIVERARE or Master Lock’s keyed-alike options. If you want more combination options in a two-pack, choose Puroma’s 4-digit cable locks; if easy visual identification matters, the orange Forge set is the distinct pick. Match the lock to your zipper pulls and travel habits, then remember that none of these locks replaces sensible care of valuables.
