While most security checks are done electronically, some suitcases are opened and checked manually by the TSA (Transportation Security Administration). When security personnel check out a bag manually, they have no choice but to break the lock—unless that lock is a TSA approved lock! Formulated in tandem with the TSA, these unique locks and straps can be opened by security personnel using a special master key. Identifiable by the distinctive icon, TSA approved locks ensure that your lock remains intact, protecting your luggage wherever you go.
