In 2026, the TSA will only cut your lock if they need to perform a physical inspection of your bag and the lock is not "TSA-Approved." TSA-approved locks (identifiable by the "Travel Sentry" red diamond logo) are designed with a master keyhole that allows security officers to open, inspect, and relock your bag without damage. If you use a standard padlock or a high-security non-approved lock, and your bag triggers an X-ray alert—perhaps due to a dense item like a power bank, a metal water bottle, or "perfectly packed" electronics—officers are legally authorized to sever the lock to complete their search. They will not reimburse you for a destroyed lock. For 2026 travelers, a high-value "pro-tip" is that if you find a "Notice of Baggage Inspection" inside your bag and your lock is gone, it means your bag was flagged. To avoid "luggage nightmares," always use a TSA-compliant lock or use heavy-duty zip ties, which officers can easily replace if they need to look inside.
