⚡ 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 — 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 — 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 — 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 — 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.

After 40+ trips across 25 countries, I've developed a clear-eyed view of what travel locks are for — and what they're not for. The honest answer: a combination lock doesn't stop a determined thief. It stops an opportunistic one.
The actual use case for a luggage lock is deterrence. Checked luggage handlers in airports and porters in hotels see hundreds of bags. A bag with no lock is trivially faster to access than one with a TSA lock. Your Forge cable lock doesn't stop someone with bolt cutters — but it does slow down a 30-second grab-and-go theft. For checked bags in most travel situations, that deterrence level is sufficient. The people rifling through airport luggage are looking for unlocked, easy-access bags, not engaging in sustained break-in attempts.
Where locks genuinely don't help: against professional pickpockets, in hostels where a determined person has unlimited time, or when your bag is left completely unattended in an unsecured location. In these scenarios, a PacSafe security bag or keeping valuables on your person is the correct answer rather than a luggage lock.
I've had the Forge TSA cable lock on my main checked bag for 3 years. It's gone through 40+ flights, been through two TSA inspections (I could tell because the lock was left in a different position, indicating it was opened with the master key), and still works perfectly. The cable lock design is specifically valuable for backpacks and duffel bags with multiple zippers — I loop the cable through all four zipper pulls and lock them together, which means the bag can't be opened without defeating the lock or cutting the cable.
Frequently Asked Questions
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.
