Best TSA Locks (2026): Combination Padlocks TSA Can Open and Relock
Organizers
The best TSA locks let screeners inspect a checked bag without cutting your zipper. These two sets cover a tough combination padlock and an alert-style lock.
Our picks
A lock on a zipper is not a vault. The best TSA locks exist so airport screeners can open a checked bag with a Travel Sentry key, look inside, and lock it again instead of cutting your zipper. That is the whole job.
We compared TSA-accepted claims, shackle style, combination vs key, and inspection alerts. A useful lock survives a real flight and still opens at the hotel. Confirm the shackle fits skinny zipper pulls before you buy a bulky padlock.
Pair a lock with identification. A lock does not help if the bag is delayed and nobody can read a luggage tag. For long trips, see the international travel packing list.
TSA lock vs regular padlock
TSA-accepted locks have a Travel Sentry cylinder. Screeners have the matching keys. A hardware-store padlock does not. If that bag gets pulled for inspection, the lock often gets sacrificed.
Use a TSA lock on checked luggage. Leave carry-ons unlocked or use the bag’s built-in zipper only as convenience, because you keep that bag with you.
A lock also does not replace packing so the bag can be opened. If you overstuff zippers until they barely meet, screeners (or you) will struggle either way.
Side-by-side tradeoffs
Master Lock is the simpler “put it on the bag and fly” pick. Forge adds a way to see that someone with a TSA key opened the lock. Neither one makes the suitcase unstealable.
Top pick: Master Lock 4696T TSA Approved Combination Luggage Lock, 2 Pack
Best for: Most checked bags and travelers who do not want keys.
The Master Lock 4696T TSA Approved Combination Luggage Lock, 2 Pack uses a metal body and an extended steel shackle. That extra reach matters on thick hasps, some equipment cases, and zipper pulls that do not sit close together.
You set a four-digit combination. There are no keys to leave in a hotel safe. The lock is TSA-accepted, so screeners can inspect and relock it. The two-pack covers one checked suitcase plus a spare or a second bag.
The common tradeoff is size. This is a real padlock, not a tiny zipper cable. If your bag only has skinny zipper pulls, confirm the shackle fits before the trip. The pair is useful when you check two bags.
Set the combination at home, then write it down somewhere that is not inside the locked suitcase.
Buy if: You want the best TSA locks for ordinary checked luggage without extra features.
Best with inspection alert: Forge TSA Approved Luggage Locks, Black 2 Pack
Best for: Travelers who want to know if screeners opened the bag.
The Forge TSA Approved Luggage Locks, Black 2 Pack adds a red indicator that pops up after the TSA key is used. You still set a combination. After an inspection, you reset the indicator when you put in your code.
Forge also emphasizes a relock design so the screener has to close the lock to retrieve the key. That does not make the bag theft-proof. It does reduce the “found my zippers wide open at the carousel” story.
The alert window and alloy body are the reasons to pick this lock. First-time setup is the hurdle. Follow the included reset steps once, slowly. A lock you cannot open at the hotel is worse than no lock.
Buy if: You check bags often and want a visible inspection signal.
How to use TSA locks without creating a problem
Lock both zipper pulls together on a checked bag. Leave a little slack so the zipper can move. Do not lock a bag so tight the slider cannot park.
Keep the combination in a password manager or a photo stored in the cloud. Do not put the only copy of the code in the locked bag.
If you also use a luggage strap, put the lock on the zipper, not on the strap buckle, unless the strap is designed for that. Mixing hardware in a knot helps nobody at inspection.
Common mistakes
Using a non-TSA padlock on a US-bound checked bag. Setting the combination to 0000 and never changing it. Locking a carry-on and then arguing at the checkpoint. Expecting a $12 lock to stop a determined thief.
Another mistake is locking a bag that is already overfilled. Screeners still need to open it. Give the zippers room to work.
Which TSA lock should you buy?
Buy the Master Lock 4696T two-pack if you want a durable, keyless default. Buy the Forge two-pack if the inspection indicator is worth a slightly fussy first setup.
The best TSA locks are the ones you can open at 11 p.m. in a hotel hallway. Set the code once at home, confirm the shackle fits, and treat the lock as a courtesy to your zippers, not as a security system.
Frequently Asked Questions
What are the best TSA locks for most travelers?
The Master Lock 4696T two-pack is the best TSA locks set for most checked bags. It is a metal combination padlock TSA screeners can open and relock, and you set your own four-digit code.
Do I need a TSA lock on a carry-on?
Usually no. You keep a carry-on with you. TSA locks are for checked luggage, where screeners may need to open the bag in a back room.
Will TSA cut a non-TSA lock?
They can. If screeners cannot open a lock with a Travel Sentry key, they may cut the lock or the zipper. A TSA-accepted lock exists so they can inspect and relock without destroying the bag.
Do TSA locks stop theft?
They deter casual zipper opening. They do not make a suitcase theft-proof. A determined thief can still attack zippers or the shell. Use a lock as a delay, not as a vault.
Should I lock a bag on a cruise or in a hotel?
A TSA lock is built for airport screening. In a hotel, a lock on the zipper can still discourage casual rummaging. It is not a substitute for using the in-room safe for passports and extra cash.
What if I forget the combination?
Reset instructions only help if you still know the current code or the lock is open. Write the code in a password manager, not on a sticky note in the bag. Some keyed TSA locks avoid this problem but add keys to lose.
Can I use the same TSA lock on two zippers?
Yes if the shackle fits both zipper pulls. That is the usual setup on a checked suitcase. Confirm the pulls actually meet before you buy a short-shackle lock.
