โก Quick Answer
The Forge TSA Approved Cable Lock (~$24) is the best TSA lock for most travelers. Flexible steel cable secures multiple zippers or attaches your bag to a fixed point โ more versatile than a standard padlock. Always use TSA-approved locks for US domestic checked bags.
Do You Actually Need a Travel Lock?
For checked bags on US domestic flights: yes. TSA agents have the legal right to open and inspect your checked baggage. If your bag has a non-TSA lock, they'll cut it off โ and it won't be replaced. TSA-approved locks (marked with the red diamond logo) let agents use a master key, inspect your bag, and re-lock it without destroying anything.
For carry-on bags: less critical, since you're keeping the bag with you. But locking a carry-on is useful when you gate-check it (common on regional jets) or leave it in a hostel storage room.
The Forge TSA Approved Cable Lock ($24) is the most versatile option โ the flexible steel cable secures multiple zippers together or loops around a fixed object, making it useful in more situations than a standard padlock.
TSA Lock vs. Regular Padlock: Which to Use Where
| Situation | Lock Type | Why |
|---|---|---|
| US domestic checked bag | TSA Lock required | Non-TSA locks get cut off |
| International checked bag | Either works | Most countries don't use TSA keys |
| Hostel locker | Any combination lock | No customs inspection here |
| Carry-on zippers | TSA lock (if gate-checked) | May be inspected at gate |
TSA Locks โ Why They Matter
TSA agents in the US have master keys that open TSA-approved locks. If your bag is selected for inspection and has a non-TSA lock, they will cut it off. TSA-approved locks display the red diamond logo. All domestic US checked bags should use TSA-approved locks.

Do I need a TSA lock for international travel?
For US domestic flights: yes, for checked bags. For international: depends on the country. Most countries use their own customs agencies that don't have TSA keys, so a standard padlock is fine. For connecting through a US airport, use TSA-approved.
Can TSA break my lock?
If it's not TSA-approved, they can and will. TSA-approved locks have master keys distributed to TSA agents. Your lock stays intact.
