What Home Lock Rekeying Actually Changes — and What It Doesn't
Rekeying alters the internal pin stack inside your lock cylinder so that the old key can no longer operate it. The lock body, the hardware, the strike plate, and the door frame stay exactly as they are. A skilled technician removes the cylinder, replaces the driver pins and key pins with a new combination, then reassembles everything — often without leaving a single scratch on the door or finish. This is why rekeying is the preferred first step after a move or key loss rather than a full home lock change: if your hardware is structurally sound and the deadbolt or mortise lock is performing well, there is no reason to replace the entire unit just because the key combination is compromised.
It is worth understanding the distinction because it also defines the limits of rekeying. If your mortise lock's case is cracked, if a door knob lock spins freely when it should not, or if the cylinder shows signs of drilling or picking attempts, rekeying alone is not enough. In those cases our technicians will explain exactly what they find and recommend the right repair or replacement — always with a confirmed up-front price before any work begins. Factors that shape the final quote include the number and type of locks being serviced, the complexity of the hardware (a high-security mortise lock has more components than a standard pin tumbler), whether parts need to be sourced, and the time of day your call comes in.
