What Home Lock Rekeying Actually Does — and Why It Beats a Full Lock Change
Rekeying works by replacing the pin tumblers inside your existing lock cylinder so that only a brand-new key will operate it. Every old key — including copies your landlord, previous tenant, ex-partner, or contractor may have made — becomes instantly useless. The lock body, the hardware, and the finish all stay in place, which matters a great deal in New York City apartment buildings where landlords often restrict unauthorized hardware changes or where a beautiful original mortise lock deserves to be preserved rather than swapped out. A home lock change makes sense when the hardware itself is damaged, worn, or severely outdated, but in most cases rekeying achieves the same security outcome with less disruption and no holes drilled into your door.
Our technicians are skilled in rekeying virtually every residential lock type found across New York's wildly varied housing stock — from modern Schlage and Kwikset cylindrical knob and deadbolt sets in newer builds, to the classic New York City mortise lock found in pre-war walk-ups from Harlem to Flatbush. The mortise lock is a core part of what we do: its internal mechanism requires a trained hand to disassemble, repin, and reassemble correctly, and our team has done it hundreds of times across the boroughs. If you're unsure whether your door has a mortise lock or a standard cylindrical set, describe it to us when you call and we'll come prepared.
