Sticking Keys and Frozen Cylinders
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.
Misaligned Deadbolts and Settled Doors
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.
When Repair Beats Replacement
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.
Common Questions
My lock is frozen, what should I do right now?
Don't force the key and don't use hot water; it refreezes inside the cylinder. Call us, proper thawing and lubrication opens it without breaking anything.
How do I know whether to repair or replace?
Quality hardware with a specific fault is usually worth repairing; cheap hardware that already failed usually isn't. We assess on site and quote both honestly.
Can you fix my lock without changing my keys?
In most repairs, yes, alignment fixes, cleaning, and hinge work leave your existing keys working exactly as before.
Do you do repairs at night and on weekends?
Yes, 24/7 across all five boroughs, since a lock that won't latch can't wait until Monday.
