What Home Lock Rekeying Actually Changes — And What It Leaves Alone
Inside every pin-tumbler lock cylinder is a stack of driver pins and key pins. When a locksmith rekeys your lock, those pins are removed and replaced with a new set calibrated to a freshly cut key. Your existing deadbolt housing, strike plate, door prep, and finish stay exactly where they are. Nothing is drilled, forced, or damaged in the process. The result is a lock that is mechanically unrecognizable to any previous key — your old spare, the landlord's copy, the neighbor who watched the house — while looking completely identical from the outside. For most standard deadbolts and door knob locks throughout a typical Marshallton home, a full rekey takes well under an hour per lock.
Rekeying works on the vast majority of residential hardware: Kwikset, Schlage, and most other common pin-tumbler cylinders. It also works on mortise lock bodies, which are frequently found in older Marshallton homes and rowhouse-style construction throughout the greater Wilmington corridor. A mortise lock is the rectangular cartridge that sits recessed inside the door edge, combining the latch, deadbolt, and sometimes a passage function into one elegant unit. Rekeying a mortise lock cylinder requires a technician who understands that hardware specifically — our team handles them regularly and carries the appropriate tooling and replacement pin kits on every service vehicle.
