Do you need a new lock or a rekey?
Rekeying keeps your lock and changes which key works it. It suits a lock that is in good shape when you only need old keys to stop working. See lock rekeying.
A lock change replaces the hardware. It makes sense when the lock is worn or damaged, or when you want a different style or better security. We look at the lock and tell you which option fits before any work starts. More in rekey or replace locks.

Multipoint doors
Long locking strips with several locking points. See multipoint lock repair.
Stores and offices
Commercial doors and groups of locks. See commercial locksmith services and master key systems.
Choosing a lock that fits
A new lock has to match the holes already in the door, the door thickness and the way the door opens. If it does not, the door may need extra work, so we check this first.
A strong lock also depends on what it locks into. If the frame is split or the strike plate is loose, we point that out and quote it separately. See door strike plates.
Want one key for several doors? Tell us when you call, because it depends on the locks you choose.
