How do you set a tsa lock on a suitcase?

To set a TSA lock on a suitcase, first, ensure the lock is in its default, unlocked position. If it has a combination, typically, you’ll need to set it to the factory default (often 0-0-0). Press the reset button (or switch) using a small tool, then set your desired combination by turning the dials. Release the reset button, and your new combination will be set; test the lock to ensure it works properly.
