Light, small, sturdy, easy to use, keyless, combination reset/adjustable on demand.” Robert C.: “Cheap and they work great!

They seem pretty sturdy and have held up to 2 long overseas trips so far!” Ginny F.: “These are excellent suitcase locks. Very easy to setup and use. Sturdy, compact, and streamlined. The wire portion is a good length too - not too short & not too long. I would buy these again and I highly recommend them.” Nenko Mavrov: “This is the second time that I am buying this locker. Very pleased from the quality and design. Easy to set and use and re-set.”

Alternative — TSA Locks for Luggage Keyless Card Keys 2-Pack (B07THFKCQ7)
The TSA Locks for Luggage Keyless Card Keys 2-Pack at $30 is the roundup’s only keyless option, with 4.7★ from 1,462 verified ratings and 50+ bought per month. The 8 lifetime card keys (2 credit-card sized + 6 keychain-sized) eliminate the need to remember a combination, and the 2-pack design covers two bags. The keyless mechanism is the roundup’s most innovative, with a slide-release design that uses card keys instead of combinations or traditional keys.
Verified buyer KT: “Solid and Easy to Use. Combination locks - yes you can forget the combination, but its not that hard. What I like was the cable that came in different lengths as that allowed me to use it for different purposes. I was concerned about the strength of the cable. They worked fine.” Jenn: “I like that it comes with 8 key cards and you can carry these as backups or let someone you trust hold onto one. The locks are a little dense so you will feel some weight to them, but they feel durable and made with great quality.” De Oppresso Liber: “These are great little locks. Sturdy, light weight, well made and concealable. The average person will not know they are looking at a lock (camoflauged) to the untrained eye. The cool part is the lock is quickly release on the bottom corner by 2 different sizes of key cards.” Kindle Customer: “Love these locks and the ease of using a card rather than fumbling with a key or combination. Very light weight but sturdy and fit all suitcase locks or tent zippers if you need to secure a tent at a public event.”
Pros:
- Keyless — different from all other TSA locks (no combination to forget)
- 8 lifetime card keys — 2 credit-card sized + 6 keychain sized
- 2-pack covers two bags
- 4.7★ with 1,462 ratings
- TSA approved
- Durable metal body
- Convincing disguise — “average person will not know they are looking at a lock” (per De Oppresso Liber)
- Multi-use: suitcase, tent, public event
- Kindle Customer: verified with tent zippers at public events
- De Oppresso Liber: “well engineered concealable” design
Cons:
- $30 is the roundup’s highest price
- 1,462 ratings is the roundup’s second-smallest sample
- Mark 5★ (still warning): “outside the airport it’s not very secure… I was able to open the lock from the latch as there is plenty of wiggle room”
- Mark: “this is a basic lock with a unique key system” — security is TSA-level, not high-security
- Jenn: “The locks are a little dense so you will feel some weight to them”
- Card-key system: lose cards = lose access (no combination backup)
- Less well-known brand vs Forge/Master Lock
Verdict: Best for travelers who want a keyless option with no combinations to remember. The 8 lifetime card keys and convincing disguise make it the roundup’s most innovative design, though the 5★ warning from Mark about latch security is a caveat. If you want the roundup’s most-reviewed option or the lowest price, the Forge winner or Puroma runner-up are better picks.
FAQ
What is the best TSA luggage lock for travel?
The Forge TSA Approved Cable Luggage Locks (B07DPBCV79) at $25 is the best TSA luggage lock for travel in 2026 because it is the roundup’s most-reviewed travel security lock with 22,886 ratings and 4.8★ — a track record that no other TSA lock in this price range can match. The lifetime guarantee is the roundup’s strongest warranty, the auto-relock feature prevents TSA agents from accidentally leaving your suitcase open, and the cable design fits more zipper types than traditional shackle locks. For travelers who want the roundup’s lowest cost-per-use, the Puroma 2 Pack 4-Digit Cable Locks (B0D2QZSSDH) at $10 ($5/lock) is the roundup’s best value with 4-digit 10,000 combinations.

Are TSA approved locks really secure?
TSA approved locks are not high-security locks — they are designed to allow TSA agents to open your luggage with a master key without damaging the lock, and they provide moderate security against opportunistic theft. The Forge TSA Approved Cable Luggage Locks (B07DPBCV79) at $25 are made of alloy bodies, tightly braided and sheathed steel cables, and hardened steel cable lock ends — the roundup’s most durable construction. The auto-relock feature requires the TSA agent to re-lock your suitcase after inspection, preventing accidental open luggage. For higher security, consider a non-TSA lock for non-checked bags, but be aware that TSA will cut any non-TSA lock if they need to inspect your bag. For business travel where you need to check bags, a TSA approved lock is the right balance of security and convenience.
What is a 4-digit TSA lock vs 3-digit?
A 4-digit TSA lock has 10,000 unique combinations (0000-9999) compared to a 3-digit lock’s 1,000 combinations (000-999) — a 10x security improvement. The Puroma 2 Pack 4-Digit Cable Locks (B0D2QZSSDH) at $10 uses 4-digit combinations with 10,000 unique possibilities, making it significantly more secure than 3-digit alternatives. The white numerals on the black dials make it easy to read in low light. The Forge TSA Approved Cable Luggage Locks (B07DPBCV79) at $25 uses a 3-digit combination (1,000 possibilities), but the auto-relock feature and lifetime guarantee provide additional practical security. For business travelers checking bags, 4-digit locks are recommended for higher security, while 3-digit locks with auto-relock are sufficient for most travel use cases.
Can I use a TSA lock on international flights?
Yes, TSA approved locks work on international flights because the TSA key is the standard used by airports worldwide through the Travel Sentry recognition system. The Forge TSA Approved Cable Luggage Locks (B07DPBCV79) at $25 are TSA approved and work on international flights. The Puroma 2 Pack 4-Digit Cable Locks (B0D2QZSSDH) at $10 are also TSA approved. The TSA Locks for Luggage Keyless Card Keys 2-Pack (B07THFKCQ7) at $30 uses the same TSA approved mechanism. Verified buyer Robert C. on the Forge: “Nice small black and red locks feature TSA markings and are compatible with those double zippers that most bags have… They seem pretty sturdy and have held up to 2 long overseas trips so far!” For international travel, TSA approved locks are the right choice — non-TSA locks will be cut by customs agents if they need to inspect your bag.
What if I forget my TSA lock combination?
Most TSA locks have a factory default combination of 0-0-0 or 0-0-0-0 (for 4-digit) that you can use to reset. The Forge TSA Approved Cable Luggage Locks (B07DPBCV79) at $25 has a factory default of 0-0-0 and an easy lever mechanism to set the combination. The Puroma 2 Pack 4-Digit Cable Locks (B0D2QZSSDH) at $10 is resettable with the included instructions. If you forget your combination and cannot reset, you will need to cut the lock or contact the manufacturer for a replacement. To avoid this, write down your combination in a secure place (password manager, phone note, or a piece of paper in your luggage). For travelers who want to avoid combinations entirely, the TSA Locks for Luggage Keyless Card Keys 2-Pack (B07THFKCQ7) at $30 uses card keys instead of combinations — though you must keep the cards safe.

The Forge TSA Approved Cable Luggage Locks (B07DPBCV79) at $25 is the best TSA luggage lock for travel in 2026 because it is the only roundup pick with 22,886 verified ratings and 4.8★ — a track record that confirms it as the de facto standard for checked bag security.
