The fact is, of the 1.4 million checked bags the TSA screens daily, only about 5% of checked bags are actually opened by agents for further inspection. Many travelers feel safer knowing that their luggage is secure while others don’t want to have to worry about remembering one more thing. Using a TSA lock is totally a matter of personal preference. To reset most built-in locks, simply slide the lock button in the direction of the arrow, set your new code and release the button.

Release the shackle and turn it back to the lock position.

Press the shackle and keep it down while you set your three-digit combination.

Rotate the shackle 90 degrees from the lock position.

Again, you may be best off checking the brand’s website for individual instructions, but you can reset most freestanding locks this way: If you forget your combination while the lock is still open, all you have to do is reset it with a new combination.

When all three numbers are correct, the lock will open.

Put pressure on the locking mechanism by pushing the button or pulling on the lock.

Here’s another method that has worked for travelers with TSA padlocks:

If the lock doesn’t open, turn all three dials down one number.Repeat the process for the other two dials.Turn the dial and, with the safety pin, look for an indentation or gap in the cylinder.

The flashlight and camera on your phone can help you zoom in on it. Use a safety pin to locate the metal or plastic cylinder on the right side of the first dial.If the idea of that is overwhelming and your luggage features a built-in TSA lock, you can try this: Although, admittedly, this seems time-consuming, they assure it should take 30 minutes or less, especially if the first number is a 0, 1 or 2 (something to keep in mind when you’re coming up with a new combination). Travel Sentry, whose red diamond logo certifies that a lock is TSA-approved, recommends trying every possible combination from 000-999, starting with 000, 001, 002 … and working your work to 999.
