What Residential Lock Rekey Service Actually Does to Your Lock
A lock cylinder contains a set of small spring-loaded pins cut to match the peaks and valleys of your current key. During a lock rekey, a trained technician removes the cylinder from your door — whether that is a mortise lock set into the edge of a solid door, a standard door knob lock, a deadbolt, or a multi-point system — and replaces those internal pins with a new configuration that matches a freshly cut key. The result is mechanically identical security with a completely different key profile. Anyone holding the old key cannot turn the cylinder. No new lock purchase is required unless the existing hardware is damaged, worn, or otherwise inadequate.
This matters most in Queens, where housing stock ranges from pre-war multi-family buildings with original mortise lock bodies to newer co-ops and condos fitted with Grade 1 deadbolts or smart lock rekey-compatible electronic cylinders. A mortise lock, common in older Queens rowhouses and apartment buildings, has a full lock body recessed into the door and requires a specific cylinder removal process — something our technicians handle routinely. Whether your door uses a traditional mortise lock set, a Kwikset or Schlage pin-tumbler deadbolt, a Yale lock rekey-compatible cylinder, or a connected smart lock with a rekeyable core, we carry the correct tooling and replacement pin kits for each type.
