Security Door Lock Being Rekeyed on Residential Entry

This image shows a close-up of a technician working on the locking mechanism of a residential metal security door. The door features both a standard knob and a deadbolt setup, often found on storm or wrought-iron doors. Rekeying or servicing these types of locks provides better access control for homeowners without replacing the entire unit. This type of work is typically done on-site during home security updates or key changes.
