What a Professional Lock Rekey Service Actually Does to Your Locks
Inside nearly every pin-tumbler lock — whether it is a Kwikset deadbolt on a bungalow near Irvington's Nye Avenue corridor or a Schlage mortise lock on a multi-family building off Clinton Place — sits a cylinder packed with spring-loaded pins of varying heights. Your key lifts those pins to an exact shear line, allowing the cylinder to rotate. During a lock rekey, our technician removes the cylinder, replaces the existing driver and key pins with a new combination, and reassembles everything so only the newly cut key operates the lock. The old key — including any unauthorized copies — no longer turns the cylinder. Nothing about the door, the strike plate, or the external hardware changes unless you request it.
This is why a lock rekey is the go-to solution after a move-in or tenant change rather than automatically pulling every lock off the door. A full deadbolt lock replacement or mortise lock replacement is absolutely warranted when a cylinder is damaged, corroded beyond function, or you want to upgrade to a higher security grade — and we do that work too. But if the hardware itself is sound, rekeying achieves the same security reset at a fraction of the material cost. Our technician will assess each lock honestly and walk you through the recommendation before a single tool touches your door.
