A TSA key for latches, often referred to as a TSA-approved key or lock, is a specialized type of key or lock that is designed to be used on luggage and travel-related items. TSA stands for the Transportation Security Administration, a U.S. government agency responsible for security in transportation, including air travel.

TSA-approved locks are used to secure luggage, baggage, and other containers while allowing TSA agents to inspect them without damaging the lock or the item.
