What Home Lock Rekeying Actually Involves — and Why It Beats a Full Lock Change
Inside every keyed lock cylinder is a set of spring-loaded pins of varying heights. When the correct key is inserted, those pins align perfectly at the shear line and the cylinder turns. Rekeying replaces those pins with a new set matched to a freshly cut key, making every previously cut key inoperable. Because the lock body, the strike plate, and the door hardware all stay in place, the process is faster and less disruptive than a full home lock change — and it eliminates the need to patch screw holes or repaint a door frame. That said, if your current hardware is worn, damaged, or simply outdated, our technician will let you know and can swap in new cylinders or full lock sets on the same visit.
A full home lock change makes more sense when the lock mechanism itself is failing, when you are upgrading from a basic door knob lock to a higher-security mortise lock, or when you want to take advantage of modern keyway technology. Many older homes in Graniteville still carry lever or knob sets with thin cylinders that offer minimal pick resistance. Upgrading to a quality Schlage or Kwikset mortise lock at the same appointment is something our technicians handle routinely, and it pairs well with a same-key rekeying so every upgraded door responds to one master key.
