How do I set up my TSA lock and combination?

For the initial setting, ensure the combination is set to “0-0-0”. Then, using a pen tip, push the lock faceplate’s reset button (small square with a circle to the left of combination) so that it stays down. Slide each number wheel to the 3-digit combination of your choice. Slide the unlocking mechanism so that the reset button pops back to its starting place. Your lock is now reset to your chosen 3-digit combination.

Please note that once you set your lock, no one else will know how to get in your bag—and that includes us. We suggest emailing the combo to yourself, tucking it into your passport, or saving it under a contact in your phone—anything to make sure you don’t lock yourself out.
