Travel & Luggage · TSA-Approved Luggage Locks
Will TSA cut my approved lock anyway?
Reviewer consensus
Sometimes, yes. A frequently cited thread on r/tsa documents an approved lock being cut during inspection despite working correctly, and similar complaints appear on r/TravelHacks. Reviewers recommend buying multi-packs (the 2- and 4-pack Forge and Master Lock sets are the most popular for this reason) so a single damaged lock doesn't strand you mid-trip.
