Rekey the lock, or replace it?
They solve different problems.
Rekeying keeps the existing hardware and rebuilds the cylinder so a different key operates it. The old keys stop working. It fits when the lock is in good shape and the real issue is who holds keys: a lost key, a tenant change, a departing employee.
Replacing changes the hardware itself. It fits when the lock is worn or damaged, when you need a different function or grade, or when the door is moving to a different keying system or to electronic access.
A few questions help decide:
โข Does the lock still operate smoothly?
โข Is the problem the hardware, or the keys in circulation?
โข Should this door be part of a master-key system later?
Either way, the existing hardware should be checked for compatibility with the plan before any work starts.
