A TSA Lock is a special type of lock designed for luggage that allows security personnel to open it without damaging the lock. The lock features a keyhole that can be accessed by Transportation Security Administration (TSA) agents using a master key. This ensures that your belongings can be inspected while keeping your luggage secure. Using a TSA lock is simple. Travelers can set their own combination or use a key to lock their bags. If a TSA agent needs to check the contents, they can unlock it with their master key, allowing for a smooth security process at airports.
