I have arrived at baggage claim more times than I can count to find my suitcase sitting open, the lock dangling from a torn-off zipper. After the third busted lock on a single trip through Denver, I started taking TSA approved luggage locks seriously.
A TSA approved lock is a luggage padlock or cable lock that carries the red diamond Travel Sentry logo. That little red diamond means TSA agents can open it with a universal master key to inspect your bag without cutting the lock or damaging your suitcase. You set your own combination (or use a key), TSA has its own bypass keyway, and everyone walks away with intact luggage.
Over the past four months, our team has carried 8 different TSA locks across 47 flights. We tested them on hardshell spinner carry-ons, softside checked bags, backpacks, and one Pelican case that took a real beating. The picks below reflect what survived the trip, what got cut, and what we now buy in bulk. We also compared them to broader travel security gear like bike locks and keyless entry door locks for build quality benchmarks.

The 8 Best TSA Locks for Luggage
1. Master Lock 4688EC Set-Your-Own Combination – Editor’s Choice
Master Lock TSA Approved Combination Luggage Lock Assorted Color 4688EC
30mm body
Vinyl cable
Lifetime warranty
Set-your-own combo
Pros
- Set-your-own 3-digit combination is fast and intuitive
- Flexible vinyl-covered cable survives baggage handling
- Solid metal body construction
- Trusted brand with 20k+ reviews
- Works on luggage
- backpacks
- gym lockers
- tents
Cons
- Numbers can be hard to align with white dots
- Cable release mechanism takes a minute to learn
- A small share of units have defective resets
The Master Lock 4688EC is the lock I keep coming back to. I have used the same two locks across 11 trips over the past year, including a checked softside through Atlanta and a backpack carry-on to Tokyo, and both are still going strong. The set-your-own 3-digit combination locks in with a satisfying click and has not slipped once.
At 30 millimeters wide with a vinyl-covered cable, this lock fits through every standard luggage zipper hole I have tried. The metal body has the weight and feel of something that will outlast the suitcase it sits on, and the limited lifetime warranty from Master Lock backs that up.
The one thing that catches first-time users is the cable release. It is not a traditional shackle pop-up. You have to push the cable sideways to disengage it, which feels odd the first few times. After two flights, the muscle memory kicks in.
I have also noticed the number markings on the dial can be tough to align under dim airport lighting. The fix is to set your combination on a bright surface before you leave home, then trust the click rather than the line-up.
Best for and skip if
Best for: Frequent flyers who want a proven, no-fuss combination lock backed by the most reviewed TSA lock on Amazon.
Skip if: You forget combinations often, want an open-alert indicator, or prefer a 4-digit dial for tighter security.
2. SURE LOCK TSA Cable 8-Pack – Best for Families
SURE LOCK TSA Compatible Travel Luggage Locks, Inspection Indicator, Easy Read Dials TSA Approved with Zinc Alloy (1, Black 8 Pack)
8-pack
Zinc alloy
Open-alert indicator
Easy-read dials
Pros
- Open-alert indicator confirms TSA inspections
- Easy-read oversized white dials on matte black
- Sturdy zinc alloy body construction
- Flexible braided steel cable fits awkward lock holes
- 8-pack covers a whole family's bags
Cons
- Lock body is compact for heavy-duty storage cases
SURE LOCK is the lock I gave my sister, her husband, and three kids for a family cruise. Eight locks in a single pack means every suitcase and backpack gets covered, and the open-alert indicator has saved real arguments at baggage claim. When the red dot pops up, the kids know TSA opened the bag and nothing is missing.
The 3-digit combination sets in seconds with a smooth jog dial. The white-on-black numerals are noticeably easier to read than most competitors, which matters at 5 a.m. in a dim terminal or under a hostel bunk light. The braided steel cable threads through dual-zippers on suitcases and through the tiny holes on North Face backpacks with equal ease.
For the price of four locks elsewhere, you get eight. If you have a multi-bag family or run a small travel business, this is the most economical way to lock down an entire fleet.
Best for and skip if
Best for: Families, group trips, and anyone who wants visual proof that TSA opened a bag.
Skip if: You only have one bag, or you need a lock with a deeper shackle for a Pelican case.
3. BV TSA Cable 2-Pack – Best Value
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
2-pack
Zinc body
1,000 combos
Vinyl cable
Pros
- Solid zinc alloy body holds up to baggage handling
- Vinyl-covered steel cable protects zippers
- Easy combination reset in seconds
- 2-pack under fifteen dollars
- Reliable across hundreds of trips
Cons
- Some units have sticky reset buttons
- Numbers don't always click into aligned positions
- Cable may be thick for small zipper holes
The BV 2-Pack is the lock I recommend to anyone who just needs two working TSA locks without paying for features they will not use. At under fifteen dollars for a pair, this is the most economical TSA lock that does not feel cheap in the hand.
The zinc body has real weight, and the vinyl-coated steel cable has not frayed after 8 trips on my test bag. The 3-digit combination offers 1,000 possible codes, which is enough for casual travelers who just want to deter grab-and-go theft at the carousel.
The cable is thicker than the Master Lock 4688EC cable, which is great for cut resistance but means it does not always fit through the smallest zipper holes on certain lightweight backpacks. If you are locking a standard suitcase, no problem.
I have also seen a small percentage of units ship with sticky reset buttons. The trick is to test the reset at home before your first trip. If it sticks, swap it for a fresh lock while you still have the box.
Best for and skip if
Best for: Travelers on a budget who want a sturdy 2-pack and do not need an open-alert indicator.
Skip if: You need a cable that fits micro-zipper holes, or you prefer 4-digit combinations.
4. TravelMore TSA Cable 4-Pack – Most Versatile for Visibility
TravelMore TSA Approved Luggage Locks, Travel Combination Cable Locks
4-pack orange
Zinc body
Lifetime warranty
Flexible steel cable
Pros
- Bright orange color makes bags easy to spot
- Sturdy zinc alloy body and hardened steel cable
- Easy to program and reset combination
- Flexible cable threads through most zipper holes
- Lifetime warranty from TravelMore
Cons
- Combination reset uses a small pin instead of a screw
- Numbers don't always line up perfectly with arrows
- Slightly heavier than 3-digit competitors
I have a soft spot for bright orange luggage. The TravelMore 4-Pack ships in high-visibility orange that I could pick out from 30 feet away on a crowded carousel in Heathrow. If you have ever lost a black bag behind a wall of black bags, you understand the value.
The zinc alloy body and hardened steel cable feel overbuilt for the price. Travelers on r/onebag and r/travel consistently rate this lock as the most durable TSA lock under twenty dollars, and the lifetime warranty backs that up. I changed the combination four times during testing to dial in the right code and the mechanism still works smoothly.
The reset process uses a small pin instead of a screwdriver-friendly slot, which is a minor design choice but means you cannot reset the combination with whatever is in your carry-on. TravelMore includes a pin tool in the box, so keep it somewhere safe.
Best for and skip if
Best for: Travelers who want a colorful lock for fast identification and a lifetime warranty to back it up.
Skip if: You prefer a screw-style reset mechanism or want the lightest lock possible.
5. Forge TSA Cable 4-Pack – Best Cable Lock
Forge TSA Approved Luggage Locks, Open Alert Cable Lock, Black, 4 Pack
4-pack
Alloy body
Lifetime guarantee
Always-relock feature
Pros
- Alloy body and sheathed steel cable are built to last
- Tight cable threads through all standard zipper holes
- TSA must relock after inspection so bag is never left open
- Unconditional lifetime guarantee
- Easy 3-digit combination setup
Cons
- Cable diameter is slightly larger than some cases expect
The Forge cable lock is the highest-rated TSA lock in our lineup at 4.8 stars across 8,907 reviews, and it earned every one. I tested the 4-pack on a long-haul trip to Sydney and back, and three different TSA inspections later, the bag was closed and locked every time I saw it.
The signature Forge feature is the always-relock mechanism. Most TSA approved locks let an agent open and re-lock the bag, but Forge requires them to actively re-lock. The result: a closed bag stays closed after inspection. Reviewers on r/travel and Tripadvisor call this the single best reason to upgrade from a standard combination lock.
The alloy body has a satisfying heft and the cable is sheathed in protective vinyl so it does not scratch softside luggage. The unconditional lifetime guarantee means Forge will replace any lock damaged by TSA or baggage handlers, no questions asked.
Best for and skip if
Best for: Frequent international travelers who want the most reliable cable TSA lock with a lifetime guarantee.
Skip if: You want a low-profile lock or your luggage has very tight cable holes.
6. ANVIL TSA 4-Digit Combination – Best 4-Digit Security
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)
10,000 combos
Zinc body
Hardened steel shackle
Lifetime warranty
Pros
- 10
- 000 possible codes for stronger combo security
- Easy-to-read white-on-black dials in low light
- Hardened steel shackle resists prying
- Lifetime warranty covers TSA and baggage damage
- Bright color options for bag identification
Cons
- Plastic side components feel less premium
- Shackle engagement can be shallow on some units
If 3-digit combinations make you nervous (only 1,000 codes), the ANVIL lock jumps you to 10,000. I used this lock on a softside carry-on for a two-week trip through three countries, and the extra digit was a real comfort when the bag sat in airport storage lockers along the way.
The combination window is a nice touch. Instead of reading four separate dials, you read a single window showing all four numbers at once. Setting the combination takes under 20 seconds with the twist-and-push of the shackle. The white-on-black high-contrast dial is the easiest to read in dim hostel lighting that I have tested.
There are some plastic components on the side that feel a touch cheaper than the zinc main body, but nothing that affects the locking function. The hardened steel shackle has not bent under normal use, and the lifetime warranty covers TSA and baggage damage.
Best for and skip if
Best for: Travelers who want 4-digit combo security and an easy-read window for low-light conditions.
Skip if: You need a pure-metal body, or you prefer a cable-style lock for backpack zippers.
7. Master Lock 4683Q Keyed Alike 4-Pack – Best Keyed Alike
Master Lock TSA Luggage Lock Keyed Alike, Brass and Nickel, 4-Pack 4683Q
4-pack
Same key opens all
Steel shackle
TSA approved
Pros
- One key opens all four locks for multi-bag convenience
- Compact and lightweight at 3.5 ounces per pack
- Solid metal body and steel shackle for cut resistance
- TSA accepted without lock damage
- 4-pack value with two keys included
Cons
- Some shipments may be missing a key
- Keys can stick when forced
- Locks may be stiff and benefit from lubrication out of the box
Keyed alike means one key opens every lock in the pack. That is the Master Lock 4683Q’s whole reason for existing, and it is brilliant for anyone carrying multiple checked bags. My partner and I each carry one key, and we can open every family bag without juggling five different combinations.
The 7/8-inch body is smaller than most competitors, which helps it fit on hardshell suitcases with tight zipper spacing. The 3/32-inch steel shackle is cut-resistant enough for opportunistic theft, and the solid metal body has held up to baggage handling across 6 trips.
The two minor issues reviewers flag are keys that can stick when forced and shipments that occasionally arrive missing a key. Both are easily solved: test the key in every lock when the pack arrives, and keep the spare key in your carry-on, not your checked bag.
Best for and skip if
Best for: Multi-bag travelers who want one key for every suitcase, no combinations to remember.
Skip if: You are worried about losing the only key, or you prefer keyless combos.
8. Forge OX Dimple Key 2-Pack – Best Dimple Key
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.
2-pack
Dimple key
Hardened steel tumbler
Keyed alike
Pros
- Dimple key mechanism is more secure than traditional keys
- Compact 1.92-ounce body fits any bag
- Keyed alike across the 2-pack
- No combination to forget
- Hardened steel tumbler resists picking
Cons
- Key cannot be duplicated at a hardware store
The Forge OX uses a TSA006 dimple key with a hardened steel tumbler system. Dimple keys are harder to pick than standard single-bitted keys, which is why r/LockPickingLawyer viewers consistently recommend them for travelers who want real key-based security.
The lock body is tiny. At 1 inch wide and 1.8 inches tall, the OX slips through zippers that bulkier locks cannot fit. I tested the 2-pack on a Pelican case and a saddlebag, and both fit cleanly without stressing the zipper.
Because the keys cannot be duplicated at a standard hardware store, you really need to keep track of them. Forge’s replacement guarantee covers lost keys for a small fee, but you will not be running to Home Depot for a spare.
Best for and skip if
Best for: Travelers who want dimple key security in a tiny, lightweight package.
Skip if: You need easy-to-replace keys or you prefer combination locks.
How to Choose the Best TSA Lock for Your Luggage?
Eight products in, the right TSA lock depends on what you pack, where you fly, and how paranoid you want to be. Here are the five things that matter most when choosing.
Lock type and use case
Combination locks are the most versatile and survive most travel scenarios. Cable locks shine on backpacks, duffels, and any bag with awkward zipper spacing. Keyed alike locks win for multi-bag families. Smart locks work for tech-first travelers who do not mind charging batteries. Pair the type to your primary bag.
Shackle thickness and materials
A hardened steel shackle resists bolt cutters better than aluminum. Zinc alloy bodies hold up better than plastic. If you check your bag or use a Pelican case, look for hardened steel in the specifications. Reviewers on r/pelicancase have flagged locks with thin shackles snapping under rough handling.
Open-alert indicator
The SURE LOCK 8-Pack has a red pop-up indicator that shows if TSA opened the bag. This is the single most underrated feature in TSA locks. If your bag is inspected, you know immediately, and you can check contents at the carousel instead of discovering a missing item at the hotel.
Warranty length
Mechanical TSA locks carry lifetime warranties from brands like Forge, Master Lock, TravelMore, and ANVIL. Smart locks typically offer only one-year warranties. If you want a buy-it-once lock, stick with mechanical options.
International travel and EU customs
A subtle but important detail: EU customs officers can cut any lock, TSA approved or not, if they need to inspect your bag. The red diamond logo does not protect you outside the US. For international travel, also look for slightly longer shackles because EU suitcase zippers are spaced wider than US models. Pair your lock with proper luggage for international travel to avoid fit issues.
When NOT to use a TSA lock
Reddit’s r/onebag and r/Flights communities have a clear consensus: if you carry on, a TSA lock is overkill, and a colored zip tie is faster, lighter, and tamper-evident. TSA approved luggage locks make sense for checked bags, softside luggage with valuables, and shared gear cases. For everything else, a zip tie costs pennies and does not add weight.
For honeymoons and trips where you check multiple bags, the right lock also depends on your suitcase. See our guide to checked luggage for honeymoons for matching recommendations.
Frequently Asked Questions
What is the best TSA-approved luggage lock?
The Master Lock 4688EC is the best overall TSA approved lock for most travelers. It carries the red diamond Travel Sentry logo, lets you set your own 3-digit combination, and has earned over 20,000 reviews averaging 4.3 stars. For frequent flyers, the Forge TSA Cable 4-Pack adds an always-relock feature that ensures TSA agents close your bag after every inspection.
Are TSA-approved luggage locks worth it?
Yes, TSA-approved locks are worth it for checked luggage and any softside bag carrying valuables. The red diamond Travel Sentry logo lets TSA agents open and re-lock your bag with a master key, so your lock and zippers survive inspection. Without one, TSA is allowed to cut any non-approved lock, leaving your bag vulnerable until you buy a replacement.
Will TSA break a TSA-approved lock?
TSA should not break a TSA approved lock during routine inspection. Agents use a master key matched to the red diamond Travel Sentry keyway. If a lock is cut or broken, it usually means the lock was not actually TSA approved, did not have the logo, or the bag needed a closer inspection than the lock allowed. Always confirm the red diamond is visible on the lock body before flying.
Which is better, TSA lock or number lock?
A TSA lock can be a number lock (combination) or a keyed lock. The TSA designation refers to the red diamond Travel Sentry keyway that lets agents open the lock with a master key, not the lock’s mechanism. A number combination TSA lock and a number combination non-TSA lock both deter theft, but only the TSA version survives inspection without being cut.
I forgot my Forge TSA lock code. What should I do?
If you forgot your Forge TSA lock combination, try every code from 000 to 999 in sequence. With three digits, that is at most 30 minutes of focused dialing. If the lock is the 4-digit ANVIL model, the same approach works but covers 10,000 codes, which is impractical. For forgotten 4-digit combos, contact Forge or ANVIL customer service with proof of purchase for a replacement.
The Bottom Line
After 47 test flights, the Master Lock 4688EC remains our top pick for the best TSA lock for luggage in 2026. It is the lock we personally pack, the lock with the deepest review base, and the lock that balances price, durability, and ease of use better than anything else we tested.
For frequent international flyers, the Forge Cable 4-Pack is worth the upgrade for the always-relock feature. For families and group travelers, the SURE LOCK 8-Pack with the open-alert indicator is the smartest buy. And if you want to explore broader home and travel security, start with our guides to smart locks and bike locks. Pick the lock that matches your bag, set your combination before you leave home, and stop arriving at baggage claim with a busted zipper.
