With these Transportation Security Administration (TSA) Combination Locks, no longer will you need to have unlocked Baggage/Shipping/Carrying Cases while traveling. The red-and-white TSA logo on the lock notifies screeners that they can unlock and relock your baggage without having to break the lock open and thus ruining a lock. With set-your-own combination convenience, you don’t have to worry about loosing a key while you travel, just remember your four-digit customizable code. TSA agents will be able to open your lock with specialized tools if they deem it necessary to inspect your luggage. The TSA now suggests you lock your checked baggage with TSA-accepted and recognized locks. These Travel Sentry™ Certified locks are accepted and recognized by the TSA. Look for the Travel Sentry™ symbol when shopping for TSA-accepted products.
