Quick Answer

Set your chosen combination on the lock, thread the cable through the zipper pulls or lockable strap, and snap the lock closed. Check that the lock engages smoothly before heading to the airport.

Why Use a TSA-Approved Lock?

TSA-approved locks allow security agents to open your luggage with a master key if they need to inspect it. Using a non-TSA lock risks having it cut off. TSA cable locks are flexible enough to secure multiple zippers or attach to a fixed ring inside your bag.

Plastic vs. Metal Cable Locks

Plastic TSA cable locks are lightweight and often transparent, making it easy to see the combination dials. Metal cable locks offer extra durability and a more premium feel. Both types use a three-digit combination and a flexible cable, so your choice comes down to weight preference and budget.

How to Install a TSA Cable Lock

  1. Set the combination: Turn the dials to the factory-set combination (usually 0-0-0). Press the reset button or push the shackle in and rotate it 90 degrees (follow your lock's instructions). Dial in your new three-digit code. Test it a few times before closing the lock. Always test the new combination with the lock open before you close it on your bag.
  2. Thread the cable through the zipper pulls: Pull the cable through the hole in the lock body. Pass the cable through the zipper pulls of the main compartment and any other pockets you want to secure. Then insert the cable end back into the lock until it clicks. If the cable is too short to reach all zippers, lock only the main compartment and keep smaller items in a locked daypack.
  3. Lock it and verify: Scramble the dials by spinning them away from your combination. Give the cable a gentle tug to confirm it is locked. For checked luggage, attach the lock to a fixed strap or handle loop so it does not dangle loose. A dangling lock can get caught in baggage-handling machinery. Secure it to a strap or handle if your bag has one.
