Function

• The TSA requires that all checked baggage pass through a security scan before being placed on the airplane. In rare instances, bags must be inspected by hand and TSA officers must have entry access to the luggage. Approved locks work with TSA officers' master keys and prevent the locks from having to be cut.
  
  

Types

• Both Travel Sentry and Safe Skies Luggage Locks are listed on the TSA website as approved locks for air travel. Travel Sentry locks are denoted by a red diamond icon, while Safe Skies Luggage Locks are identified by a red torch icon that is placed on each lock.
  
  

Considerations

• TSA-approved locks are available for purchase at many retailers both in stores and online. While non-approved locks may be used to secure luggage, their use may result in a cut lock and a bag that remains unlocked for the rest of the air travel, as TSA officers are unable to re-secure locks that have been cut.
