When should you rekey or replace a lock?
Rekeying changes which key operates a compatible lock cylinder while keeping the existing hardware. Replacing a lock changes the hardware itself. The choice depends on its condition, compatibility and the access you need to manage.
When rekeying may be enough
You moved into a home and don't know who holds copies of the old key.
A key was lost or an authorized occupant no longer needs access.
The existing lock works properly and its cylinder can be serviced.
You want compatible doors keyed alike, subject to the locks' hardware and keyway.
When to consider repair or replacement
If a latch sticks, the cylinder is damaged, the door no longer closes properly or you want different hardware, changing keys alone will not solve the underlying issue. A locksmith can inspect the door alignment and hardware before suggesting repair, rekeying or replacement. Not all cylinders are compatible with every key or keying system.
Prepare for a quote
Count the affected doors and describe the hardware, key status and any signs of damage. For a rental or shared property, confirm who can authorize changes and coordinate access. Ask for an itemized estimate and approve any new hardware before installation. When you're ready to book, see our lock change and replacement service.
