Even though your lock was "TSA-approved," there are several reasons why an agent might have cut it. The most common reason is a mechanical failure; if the TSA master key (which agents use to open these locks) becomes stuck or the internal tumbler is damaged, the agent will simply use bolt cutters to access the bag rather than delay the security process. Another reason is outdated technology; some older "TSA-002" or "TSA-007" locks have master keys that are no longer in standard rotation at all security checkpoints. Additionally, if the lock is positioned in a way that the master key cannot be inserted, or if the bag is flagged for an immediate high-threat explosive trace, the agent will bypass the lock to ensure safety. It is important to know that the TSA is not legally liable for damage to locks during the inspection process. To avoid this in the future, many 2026 travelers use cable ties (zip ties) which can be easily cut and replaced, or choose hardside luggage with integrated TSA-compliant latches that are less prone to jamming.
