A bag that leaves the carousel with a sliced zipper and a padlock in pieces is the most preventable travel disaster there is, and a TSA-approved luggage lock is the cheapest fix. When we compared the ten most-reviewed locks in the category, one stood out: the Master Lock 4688EC, a set-your-own three-digit lock with more than 20k reviews behind it.
The catch is worth saying up front. A TSA lock is a convenience and a deterrent, not a vault. Screeners open it with a master key, and the red diamond that grants that convenience is the same reason anyone else can do it too.
So we built the list around what each lock actually does. Ten made the cut, grouped by what they are good at rather than by brand.

What Is a TSA-Approved Luggage Lock?
A TSA-approved luggage lock is one stamped with the red Travel Sentry diamond logo, which means certified screening officers can open and re-lock it with a master key instead of cutting it off your bag. Travel Sentry licenses manufacturers to build around a specific dual-core cylinder, and most approved locks show a red indicator once they have been opened for inspection.
Two terms get used loosely. TSA-approved means the lock is built to that certified cylinder. TSA-accepted is the label used for a lock the agency will open even though it is not Travel Sentry certified. Either keeps your bag off the cutting table in the US.

1. Master Lock 4688EC Combination Lock: The Pick for Almost Everyone
Master Lock TSA Approved Combination Luggage Lock Assorted Color 4688EC
Alloy steel body
Vinyl-covered 1/8 inch cable
Set-your-own 3-digit code
Limited lifetime warranty
Pros
- Vinyl-covered cable survives baggage handling
- Metal body at low weight
- Combination sets in seconds
- Most reviewed lock in the category
Cons
- Reflective recessed dials are hard to read in low light
- Side-release cable action takes practice
- Reset button can be stiff
The body is metal and the shackle is a flexible vinyl-covered cable measuring 1/8 inch across, and the whole lock packs down to just under 3 inches tall. Owners describe it surviving years of trips without the dials rattling loose.
With more than 20k ratings behind it, this is the most heavily reviewed lock in our list, so the common complaints are already well known ones. For anyone buying a single lock and forgetting about it, it is the safest default.
Two details matter more than the spec sheet. The wheels sit recessed in reflective metal and are genuinely hard to read in a dark room. The cable also releases from the side of the body rather than pulling up, which feels strange for the first few uses.
Neither is a failure, and both are shared by most cable locks here. If you read your code at night, the two dial options below solve the problem.
Who this lock suits
It suits anyone with a standard hardshell or a soft bag with a single zipper pull hole, and anyone who does not want a lock adding meaningful weight to a carry-on. The 1-3/16 inch body clears larger zipper hardware than most competing locks.
Who this lock does not suit
Skip it if you need a visible tamper alert, because there is no open indicator. Skip it if you want real resistance to a determined thief, since a flexible cable is cuttable and three digits means 1000 combinations.
2. SURE LOCK 2-Pack Cable Lock: The One With the Open Alert
SURE LOCK TSA Approved Luggage Locks with Open Alert Indicator, 3 Digit Combination Cable Travel Lock for Suitcase, Backpack & Travel Bag, 2 Pack Black
Zinc alloy body
Braided steel cable
Open alert indicator
Oversized white on black dials
Pros
- Open alert shows when the lock was opened
- Large dials read well in low light
- Resettable code changes in seconds
- Braided cable fits tight zipper holes
Cons
- Reset lever is stiff to move
- Three digits only 1000 combinations
A red open alert indicator stays visible until you undo the lock with your own combination, so you know the moment you pick up your bag whether anyone opened it. That single feature separates this from most locks at its level.
The dials are the other headline. Oversized white numerals sit on matte black and stay readable in dim terminals, and the braided steel cable threads through zipper holes a solid shackle would never clear. The pair weighs 70 g.
The code resets with a pen in seconds, and the zinc alloy body with reinforced internals is weather resistant enough for a wet apron. Owners report many flights without the dials drifting.
The one real gripe is the code-reset lever, which needs a firm push. Expect that on first use rather than reading it as a defect.
Who this lock suits
It suits frequent fliers who want to know without inspecting the bag whether their lock was opened in screening, and it suits families because the pack gives you a matched pair that fits hard cases, camera bags and equipment cases.
Who this lock does not suit
It does not suit anyone who wants a wider combination space, because three digits means 1000 possible codes. Nor does it suit a bag with a very small zipper loop where even a braided cable will not pass.
3. BV TSA Accepted 2-Pack: The Budget Two-Pack
BV Luggage Locks TSA Accepted, Travel Sentry Approved 3-Digit Combination Suitcase Locks with Open Alert & Flexible Cable for Travel, Backpacks, Lockers, Cases, Black, 2 Pack
Zinc body
Keyless 3-digit combination
Flexible steel cable
2 locks per pack
Pros
- Keyless operation removes the lost key risk
- Compact body fits small zipper holes
- Cable spans two separated zipper pulls
Cons
- Reset button can be hard to depress
- Dial wheels feel loose in low light
- Shank may not pass every zipper hole
You get two locks, so you can cover a suitcase and a backpack or hand one to a companion. Each weighs 2.1 ounces and the compact body fits the small zipper hardware on handbags and medication pouches.
The combination is keyless, resettable and limited to 1000 codes. Owners usually buy it again on the next trip, and the listing is labelled TSA accepted rather than approved, which is the same practical outcome at screening.
The flexible steel cable spans two zipper pulls that do not sit side by side, and the 4 by 1 inch body clears hardware that a solid shackle would never fit.
Build quality is where the money was saved. The reset button is stiff on some locks and the wheels can feel loose enough to misalign in the dark.
Who this lock suits
It suits anyone who wants two working locks on a modest budget and wants the lost-key risk removed entirely. The cable is also the most accommodating shackle here for soft bags and backpacks with small, misaligned pulls.
Who this lock does not suit
It does not suit anyone who is rough with gear, since the dial wheels are the first thing to wear. It also does not suit you if you want to know at a glance that the lock was opened at screening, because this one has no open alert indicator.
4. TravelMore Orange 4-Pack: The Matched Set for Group Travel
TravelMore TSA Approved Luggage Locks, Travel Combination Cable Locks
Pack of four orange locks
Zinc alloy body
Hardened steel shackle
Lifetime warranty
Pros
- Four matching locks in one pack
- Bright orange makes bags easy to spot
- Hardened steel shackle resists cutting
- Includes instructions and walkthrough video
Cons
- Four locks add noticeable weight
- Numbers do not always align with the guide arrows
- Reset uses a pin rather than a screw
Four identical orange locks is a specific answer, and a good one for a group checking several bags. The colour does more work here than any other feature, because a bright orange lock is how you find your bag on a crowded carousel.
Construction is the point: a high-strength zinc alloy body with a hardened steel shackle rather than a flexible cable, 100% Travel Sentry certified, 59 g for the pack, and a lifetime warranty.
Because this is a steel shackle, it needs full-size zipper loops rather than the tight holes on hardshell cases or small backpacks. It suits duffels, larger suitcases, gym lockers, golf bags and Pelican cases.
Alignment is the detail to plan around. The numbers do not always sit perfectly against the guide arrows, so entering the code can take an extra second in a dim terminal.
Who this lock suits
It suits anyone travelling with three or four bags, since four matching locks remove the sorting-out-at-the-carousel problem, and it suits anyone who wants a cut-resistant shackle instead of a cable.
Who this lock does not suit
It does not suit carry-on weight watchers, because four metal bodies add up in a side pocket. It also will not fit bags with small or non-standard zipper hardware.
5. Master Lock 4689Q Keyed 4-Pack: Four Bags, One Key
Master Lock 4689Q TSA Approved Luggage Lock, 4 Pack, Colors May Vary
Keyed alike four-pack
Shrouded steel shackle
1 inch wide body
Four keys included
Pros
- One key opens all four locks
- Low profile hides against zipper hardware
- Shrouded steel shackle resists cutting
- Metal body feels solid
Cons
- Colors arrive at random
- Locking mechanism can feel light
- Mixed colors make keyholes harder to spot
All four locks are keyed alike, so one key opens everything and four keys are included for the rest of the group. The body is a compact 1 inch wide with a 1/8 inch shackle that sits low against the zipper.
That low profile is the reason to like it. A key lock announces itself less than a dial lock, which matters in a crowded terminal, and the shrouded steel shackle resists casual cutting better than a bare cable.
The trade-offs are the standard keyed ones. No code means no code to reset or forget, and a lost key ends the lock with no fallback.
Colours come as a random assortment, so the shade you receive may not match the listing photo, and some owners describe the internal locking piece as lighter in the hand than expected.
Who this lock suits
It suits anyone with multiple bags who would rather manage one key than four separate codes, and it suits travellers handing a key to a child or partner who will not remember a combination.
Who this lock does not suit
It does not suit anyone who loses things, since a lost key finishes the lock. It also does not suit buyers who need matching colours for bag identification, because the four locks will not match.
6. ANVIL 4-Digit Lock: Ten Thousand Combinations
ANVIL TSA Approved Luggage Lock – 4 Digit Combination, 10,000 Combinations, Easy-Read Password Window, Travel Lock for Suitcases, Backpacks, Gym & Student Lockers, Baggage(Yellow 2 Pack)
4-digit combination
Zinc alloy body
Hardened steel shackle
Dedicated code window
Pros
- 10000 possible combinations instead of 1000
- Code window shows the set code clearly
- High-contrast white on black numerals
- Combination changes in under twenty seconds
Cons
- Side panel is plastic
- Shackle sits shallow in the body
- Relatively heavy for its size
Four digits give 10000 combinations rather than 1000, and this is the only lock in the group that makes that upgrade. A dedicated combination window also shows the set code instead of leaving you reading tiny numbers from the side.
Re-keying takes under twenty seconds with a twist and push of the shackle. The body is zinc alloy with a hardened steel shackle, and the lifetime warranty explicitly covers damage by TSA and baggage handlers.
Readability is the selling point. High-contrast white numerals on black dials solve the low-light problem that most travel locks here never address.
Be realistic about security, though. The shackle does not sit deeply into the body and the side panel is plastic, so this deters opportunistic tampering rather than stopping someone prepared. Owners also note it is heavier than its size suggests.
Who this lock suits
It suits anyone who has had a three-digit lock guessed, and anyone who sets the same code on everything. The window and the high-contrast dials also suit anyone reading a code in poor light.
Who this lock does not suit
It does not suit carry-on weight watchers, and it does not suit anyone expecting serious physical security, because the shallow shackle engagement and plastic panel cap how far it goes.
7. TravelMore Keyed Barrel Lock: The Discreet Low-Profile One
TravelMore TSA Approved Locks for Luggage with Keys, Secure Travel Locks
Straight barrel key lock
Detachable wire stem
Two keys included
Zinc alloy body
Pros
- Battery-shaped profile does not advertise a valuable bag
- Detachable stem slips through almost any pull
- Two keys included
- Compact enough not to snag on carousel belts
Cons
- Heavier than expected for its size
- Cable end can be too wide for small holes
- Thin cable is cuttable
A 1.67 by 0.6 inch cylinder with a detachable wire stem does not read as luggage hardware to the person behind you at the carousel, which is the whole design argument for a lock owners rate at 4.7.
It is 100% TSA compliant on a high-strength zinc alloy body, comes with two keys, and the locks in a pack are keyed alike so one key covers the set.
The detachable stem works on zipper pulls, duffel straps, purse latches, backpacks and briefcases, a longer list of fittings than any standard padlock in this roundup.
Two cautions. The thin wire is cuttable by anyone with the right tool, and the ball-tipped end can be too wide for the smallest 1/8 inch holes. It is also heavier than the size suggests.
Who this lock suits
It suits anyone moving through crowded terminals or high-traffic destinations where the visible value of a padlock is itself the problem, and it suits awkward hardware such as duffel straps and purse latches.
Who this lock does not suit
It does not suit anyone who needs cut resistance, since a thin wire offers none, and it does not suit very small zipper hardware where the ball-tipped end is a tight fit.
8. Master Lock 4683Q Brass 4-Pack: The Solid Metal Set
Master Lock TSA Luggage Lock Keyed Alike, Brass and Nickel, 4-Pack 4683Q
Brass and nickel finish
Solid metal body
Steel shackle
Keyed alike four-pack
Pros
- One key opens all four locks
- Small and light at 3.52 ounces
- Solid metal body with steel shackle
- Strong repeat-purchase loyalty
Cons
- Keys can stick and bend if forced
- Some sets arrive with fewer than four keys
- Locks can be stiff until oiled
A solid brass-finish padlock with a steel shackle, TSA approved, sold as a keyed-alike four-pack. At 7/8 inch wide and 3.52 ounces, it is a conventional luggage padlock, which is why owners keep buying the same one.
The 3/32 inch shackle has a 7/16 inch height, a thin profile that fits most standard zipper hardware. Four locks and two keys are included and the same key opens all four.
The metal construction is what separates it from plastic-bodied budget locks. A solid body and steel shackle better survive being dropped, sat on, or forced in a crowded hold.
Maintenance is the trade-off. Keys can stick and bend if forced, locks can feel stiff until a drop of household oil is added, and sets occasionally arrive with a key missing.
Who this lock suits
It suits anyone who prefers a real padlock to a cable and wants a lock that looks built for a decade of airport handling. The brass finish also ages better than black plastic.
Who this lock does not suit
It does not suit anyone unwilling to carry a key, since a bent or lost key ends the lock permanently. Some sets also arrive short on keys, which means tracking down a spare.
9. Fosmon Multi-Color 4-Pack: The Best for Finding Your Bag
Fosmon TSA Approved Luggage Locks, 3-Digit Combination Padlock, 4 Pack
Zinc alloy body
Hardened steel shackle
Front-facing code window
Open alert indicator
Pros
- Four distinct colors for easy bag identification
- Code window faces forward
- Red indicator shows an open lock
- Anti-corrosion and weather resistant
Cons
- Numbers are small and hard to see
- Setting the first combination takes practice
- Instructions are terse
This is a four-pack where each lock is a different colour, so a group can tell at a glance which bag belongs to whom without reading a tag. That works better at a crowded carousel than a luggage tag does.
Mechanically it is a zinc alloy body with a hardened steel shackle and a rotating dial combination. The code window faces forward and a red indicator pops when a TSA key has been used.
The same locks work on gym, hostel, water park and equipment lockers, and the anti-corrosion, weather-resistant finish suits a locker that sits outdoors in winter.
The limitation is dial size. The numerals are small, so this is a poor choice if you read your code in a dark room, and the terse instructions make the first combination setting take a few attempts.
Who this lock suits
It suits families and groups, where colour-coding each bag beats matching names at the carousel, and anyone using the same locks for gym or school lockers.
Who this lock does not suit
It does not suit anyone reading a code in low light, since these are the smallest numerals on the list, nor a first-time buyer who wants hand-holding through setup.
10. Forge OX Keyed 2-Pack: The Hardest Key to Copy
Forge OX 1” Wide 1.8” Tall, TSA Approved Luggage Locks: Key Locks for Travel. Ultra Secure Dimple Key Travel Locks Alloy Body. for Luggage, Backpack, Small Toolbox and More. Black 2 Pack.
TSA006 dimple key
Alloy body with steel shackle
Keyed alike pair
1.5 oz per lock
Pros
- Dimple key resists picking better than bitted keys
- Key cannot be duplicated in stores
- Very light at 1.5 oz per lock
- Keyed alike so one key covers both
Cons
- Key must be carried at all times
- Losing the key means losing access
It uses a TSA006 dimple key with a hardened steel tumbler system, which resists picking and freezing better than the standard bitted keys most luggage padlocks use. The keys cannot be duplicated in a shop.
Each lock measures 1 inch square, weighs about 1.5 oz and uses an alloy body with a steel shackle sized for luggage, backpacks, briefcases, gym lockers, laptop bags and small toolboxes.
Both locks are keyed alike, so one key on your keyring opens both. For a family travelling together that is the point: no code to teach and no note to lose.
Owners single out the low weight and the single-key convenience as the deciding factors, and the lock holds a 4.7 rating across more than 4k reviews.
Who this lock suits
It suits anyone who wants the strongest key mechanism available for a travel lock, particularly in cold climates where a bitted key can freeze or bind, and anyone already carrying keys.
Who this lock does not suit
It does not suit anyone who would rather not carry a key, because losing it ends the lock with no combination as a backup. A fixed steel shackle also will not pass pulls a cable would clear.
How to Choose the Right TSA-Approved Luggage Lock for Your Trip
Start with dial count. A three-digit lock offers 1000 combinations, enough against opportunistic tampering but trivial for anyone determined. A four-digit lock gives 10000 and costs little more, so it is the better default unless your bag is colour-coded.
Second, match the shackle to the bag. Cable designs thread through small and misaligned zipper holes, backpacks, duffel straps and hard shells, but they are cuttable. Steel or hardened shackles resist better yet need a proper zipper loop, so check the hole size first.
Third, decide keyed or keyless. Keyless removes the risk of a lost key and simplifies multi-bag travel. Keyed gives you a stronger physical mechanism in the Forge and a more discreet profile in the TravelMore barrel lock, but a lost key ends that lock for good.
Finally, prioritise the open alert indicator if you fly often. It is the cheapest way to know whether your bag was opened at screening, and only a handful of the locks here offer one.
TSA-Approved vs Regular Lock: The Honest Take
A TSA-approved lock is worth it if you fly through or from a US airport, because a regular lock is usually cut off in screening and you lose both the lock and a piece of your bag. That is the whole case for it, and it is a good one.
What it is not is protection. TSA master keys are documented and obtainable, which means a determined thief can open an approved lock as easily as a screener can. Treat the lock as a visible marker that this bag is not an easy target.
Two further limits are worth knowing. TSA approval is a US accommodation, and foreign screening authorities generally do not carry those keys, so overseas your lock is a lock that will eventually be cut off. And screeners do not always re-secure a bag after inspecting it.
What to Do If You Forget Your Luggage Lock Combination
Work through these in order and stop as soon as one works. First, try every code you have used, including the factory default of 000 and 0000, because resettable locks sometimes sit at the setting they arrived with. Second, look for a reset mechanism: a shackle that pushes to one side, a button on the base, or a screw on the back.
Third, check the packaging or your order history for a manufacturer reset code, which some brands store against the model number. Fourth, contact the manufacturer, since most brands here publish a warranty and several will replace a lock whose code is lost.
Fifth, if none of that works and you are at a US airport, a TSA agent can open an approved lock with a master key. Anywhere else, the lock comes off.
Frequently Asked Questions
What is the best TSA-approved lock for a suitcase?
The Master Lock 4688EC is our overall pick: a set-your-own three-digit lock, a vinyl-covered cable that survives baggage handling, and a limited lifetime warranty. Add the SURE LOCK 2-Pack if a visible open alert matters to you, or the ANVIL if you want four digits and 10000 codes instead of 1000.
Are TSA-approved luggage locks worth it?
They are worth it for convenience rather than security. An approved lock is opened and re-locked at US screening instead of being cut off, saving your lock and your bag. Master keys are broadly obtainable, so a determined thief can open any approved lock, which makes it a visible deterrent.
Will TSA break TSA-approved locks?
No, and that is the point of the red Travel Sentry diamond. Screeners use a master key on the certified cylinder, so an approved lock is opened and re-secured without damage. The catch is that a screener may leave the bag unlocked afterwards, which is why an open alert indicator is worth considering.
Do luggage locks have to be TSA approved?
No, but a non-approved lock is usually cut off during screening in the US, which destroys the lock and can damage the zipper or bag. Approval is not required by law on most routes, so you can travel without one, but you accept the risk of a cut-off lock.
My TSA luggage lock won’t open. What can I do?
Try the factory default code, then look for a reset button, a screw, or a shackle that pushes to one side. Check the packaging or your order history for a manufacturer reset code and contact the brand, since most publish a warranty. At a US airport a TSA agent can open an approved lock with a master key.
The Best Luggage Locks for TSA in 2026
After working through ten locks, the Master Lock 4688EC is still the one to buy if you want a single lock and no drama. The vinyl-covered cable handles real baggage handling, the body is metal, and the review base is large enough that you know what you are getting.
Add the SURE LOCK 2-Pack if a visible open alert matters to you, or the ANVIL if you want four digits instead of three. Pick the lock for your bag rather than the brand, set the code somewhere you will remember it, and know the honest limit of what it does.
