Rekey your locks so old keys stop working
Rekeying changes the inside of a lock so the old keys no longer work, and you get new keys. The lock stays on the door. It’s usually quicker and cheaper than replacing locks.

How it works
We take out the lock cylinder, change the pins inside to suit a new key, test it and refit it. You get two new keys, and we can cut more on the spot. We do it all at your place, from the van.
Rekey or replace?
Rekey if your locks work well and you just want to control who has keys. Replace if a lock is worn, damaged or low security, or if you’d like to go keyless with a digital lock. We’ll tell you honestly which you need. See lock repairs and installs.
For landlords and property managers
Rekeying between tenants is the simplest way to keep a property secure. We agree the price with you before each job.

Common questions
Can all locks be rekeyed?
Most key-operated door locks can, including deadlocks, knob sets and many security-door locks. Some older or cheaper locks aren’t worth rekeying, and we’ll tell you if replacing makes more sense.
How long does rekeying take?
It’s usually a quick job for each lock. We’ll give you a time estimate once we’ve seen your locks.
Can you make all my locks work with one key?
Yes, if the locks are compatible, we can rekey them all to the same key.
Do you rekey car locks?
No. For cars, we can remove a lost key from the car’s computer instead. See our car locksmith page.
