Tips: Why is a TSA Lock Important? TSA stands for Transport Security Administration. TSA screens every passenger's baggage before it is placed on the plane. Occasionally, they choose to open a passenger's luggage for closer inspection. If the luggage has a non-TSA-approved lock, the lock will be destroyed to gain access. TSA-approved locks have a universal master key that can open the locks, and only the TSA has a copy of this master key.
