What is TSA lock?

A TSA lock is a type of lock that is approved by the Transportation Security Administration (TSA), which is an agency of the United States Department of Homeland Security. TSA locks are designed to be used on luggage and travel bags to secure them during air travel.


The unique feature of TSA locks is that they can be opened by TSA agents using a special master key or combination, without damaging the lock. This is important for security reasons, as TSA may need to inspect baggage without the passenger being present. If a traveler uses a non-TSA approved lock and TSA needs to inspect the bag, they may cut the lock open, potentially damaging the bag or the lock.


TSA-approved locks typically have a red diamond-shaped logo on them, indicating that they comply with the TSA’s standards. These locks are widely available and can be used to secure suitcases, backpacks, and other types of luggage. Travelers who want to secure their belongings while allowing for TSA inspections often choose TSA-approved locks for their luggage.
