Stick with TSA Approved Locks TSA agents have a master key to open TSA-approved locks, including multiple-digit combination locks. If they're unable to open your bag's lock with their master key, they will end up cutting the lock to gain access to your bag. Only use TSA-approved locks to avoid this happening.

A TSA-approved lock is a highly recommended security measure for luggage in 2026, primarily because it allows security agents to inspect your bag without causing damage. These locks feature a specific "master key" cylinder that Transportation Security Administration (TSA) agents can open using specialized keys if your bag is flagged for a manual search. If you use a non-TSA lock and your bag requires an inspection, agents are legally authorized to cut or break the lock, which often destroys the zippers or the lock itself. However, it is important to understand that these locks are designed for compliance rather than high-security theft prevention. Because the master keys have been "cloned" and designs are standardized, they won't stop a determined thief. Their true value lies in keeping your zippers closed during transit and ensuring that if your bag is selected for a random security check, you don't arrive at your destination with a broken suitcase that can no longer be secured.
