Learn how to set and use a TSA-approved luggage lock on checked bags, from choosing the right lock to securing your zippers and handling airport inspections.
Quick answer
Use a TSA-approved lock on your checked bag by setting a unique combination, locking the zippers together through the pull tabs, and keeping the combination accessible in case TSA needs to inspect your bag. Always confirm the lock has the TSA-recognized logo before flying.
Why TSA-approved matters for checked bags
Checked bags go through security screening behind the scenes. If a lock is not TSA-approved, screeners may cut it off to inspect the contents, leaving your bag unsecured for the rest of the trip. A TSA-approved lock lets agents open it with a master key and relock it afterward.
Not all locks with a combination dial are TSA-approved. Look for the Travel Sentry logo on the lock body or packaging. Without that mark, you risk losing the lock and having your bag left open.
When a lock is not the right choice
If you are carrying high-value items or medication that cannot be checked, a lock will not make a checked bag safe. Keep those items in your carry-on. Also, soft-sided bags with two-way zippers can sometimes be opened by spreading the zipper coils even when locked; in that case, a lock is a deterrent, not a guarantee.
For hard-sided luggage with a built-in TSA lock, follow the manufacturer's instructions instead of adding a separate lock. Using both can cause confusion during screening.
Step-by-step: setting and using your luggage lock
- Set your combination before you pack: Choose a three-digit code you can remember, then follow the lock's reset procedure (usually pressing a reset button or turning the shackle). Test the new code with the lock open before you close it. Common mistake: setting the code while the lock is closed, which can jam the mechanism. Write the combination in your phone's secure notes, not on a slip of paper inside the bag.
- Lock the zippers together: Slide both zipper pulls into the lock's shackle and close it. Make sure the shackle passes through the holes in the pulls, not around the fabric. Checkpoint: tug gently on each zipper to confirm the lock holds and the pulls cannot be separated.
- Confirm the TSA logo is visible: Before heading to the airport, check that the Travel Sentry logo is clearly marked on the lock. If it is worn off, replace the lock. Mistake: assuming any small padlock is TSA-approved. Snap a photo of the lock on your bag in case you need to describe it to a lost-and-found desk.
- Keep the combination accessible during travel: If TSA inspects your bag, they will relock it but may leave a notice. Keep your combination in your carry-on or phone so you can open the bag at your destination. Checkpoint: never check the only copy of your combination.
- Inspect the lock after arrival: After you collect your bag, check that the lock is still attached and the zippers are closed. If the lock is missing or damaged, report it to the airline before leaving the baggage claim area. Mistake: waiting until you get home to report tampering. A quick inspection at the carousel makes it easier to file a claim on the spot.
