Lock Repair NYC

A sticking lock is a warning, not a personality quirk. Sometimes the culprit is the key itself — years of copies made from copies drift far enough from the original cut that the pins barely cooperate — and sometimes it's grit, rust, or a worn cylinder. We diagnose which, clean and lubricate the mechanism properly, or fit a fresh cylinder if the wear has gone too far. Winter freeze gets its own rule: don't force a frozen lock, and don't pour hot water on it — it refreezes inside the cylinder and makes the morning worse. Call instead; thawing one correctly takes the right approach, not brute force.

Here's the test: if you have to lift, pull, or hip-check the door to throw the deadbolt, the lock probably isn't broken — the door and frame have drifted apart. Pre-war buildings settle, hinges sag, humidity swells old wood, and one day the bolt no longer meets the strike plate. The repair is mechanical, not magical: adjust or move the strike, shim or tighten the hinges, and the bolt glides again. It matters more than comfort — a deadbolt that only half-throws is a door that isn't really locked, and plenty of residents live behind one for years without realizing it.

Good hardware deserves repair. A solid mortise lock body in a brownstone door can outlive every tenant in the building with an occasional cylinder swap, and replacing it with a modern cheap lock would be a downgrade wearing a new-parts disguise. Builder-grade hardware flips the math — if a flimsy lock has failed once, repairing it just schedules the next failure. We tell you which side of that line your lock sits on, give a transparent quote before work begins, and let you decide with real information. No hidden fees, no inventing problems to fix.
