What Lock Rekey Service Actually Does to Your Cylinder
Inside every pin-tumbler lock cylinder — whether it's a Schlage deadbolt, a Kwikset knob lock, or a heavy-duty mortise lock — is a series of spring-loaded driver pins and key pins. The specific heights of those key pins correspond exactly to the cuts on your current key. During a lock rekey, a trained technician removes the cylinder, extracts the existing pin stack, and replaces the key pins with a new set whose heights match a freshly cut key. The driver pins and springs stay in place. When the job is done, every previously existing key is rendered useless — mechanically, not just in theory.
This matters enormously in Queens rental situations, where landlord-tenant turnover is constant and buildings in neighborhoods like Jackson Heights or Woodside may have had dozens of residents over the decades. It also matters after a breakup, a contractor visit, or any situation where someone had legitimate access and no longer should. A lock rekey is not a workaround — it is a complete credential reset for your door.
