How to Change the Combination on a TSA Lock

If you travel frequently and carry valuable belongings in your suitcase, you may want to invest in a Transportation Security Administration lock. This special combination lock cannot be opened by the average person, but can be unlocked by TSA personnel for inspection. This will allow you to protect your luggage while still complying with TSA regulations. If you want to reset your combination, you can easily change your TSA lock combination in just a few minutes.
