Dependable Lock Repair Across NYC
Golden Key Locksmith NYC repairs broken, jammed, frozen, sticking, and worn-out locks instead of replacing them whenever the hardware can still be saved — cylinders that will not turn, mortise locks that have seized, deadbolts that bind, and keys snapped off inside the lock body. We diagnose, extract, and rebuild on-site for residential and commercial doors, and if a lock is truly past saving, our licensed, bonded, and insured technicians can fit a new cylinder or complete a full lock change on the same visit. Call (212) 204-1655.

Commercial Lock Repair
Commercial locks take a beating — constant users, heavy-traffic doors, and exposure to the elements wear them down fast. The failures we fix most often are keys that no longer turn in the cylinder, locks that have seized or frozen, jammed deadbolts, and mortise lock breakdowns. When hardware is too far gone to repair reliably, our commercial locksmith team recommends and installs a replacement that meets your building’s security requirements, including high-security cylinders from Mul-T-Lock, Medeco, and Adams Rite. We handle high-security lock repair and service in-house as well — these restricted cylinders can usually be rebuilt with factory parts rather than downgraded to a lighter lock. Brooklyn businesses can reach our Brooklyn locksmith crew for fast dispatch.
Residential Lock Repair
Home locks fail in many ways — a key that will not pull back out, a cylinder that spins but never throws the bolt, or a lock that stiffens through the winter until it seizes completely. Because a malfunctioning lock is a real security risk, it should be handled the same day. Our residential locksmith team arrives with the tools and parts to finish most repairs on-site in one visit. If the lock cannot be saved, we move straight to a lock change, or for renters we can discuss whether rekeying is the more practical fix.
Emergency & Break-In Lock Repair
Break-ins and locks that fail at the worst moment both need a fast response — our 24/7 emergency locksmith service responds across all five boroughs. We assess every entry point, repair or replace damaged locks and door frames, and recommend security upgrades so it does not happen again — and we can provide documentation suitable for insurance claims. For stores and offices locked tight by failed hardware, our business lockout team gets you back in and working the same day.
Which lock problem do you have?
Most lock repair calls start with a symptom, not a diagnosis. Below are the failures we see most on NYC apartment and storefront doors, what usually causes each one, and a link to the guide that walks through the simple fixes first. If the guide ends with “call a locksmith,” that is the point where we take over.
The key turns but nothing moves
The cylinder rotates, the handle turns, and the bolt or latch stays put. That is a broken part inside the lock, not dirt or alignment: a sheared tailpiece, a worn cam, or a retractor that has let go inside a cylindrical lockset. On a mortise lock it is usually a failed hub or lever spring inside the case. We open the lock, replace the failed part, or fit a new cylinder if the body is sound. Guide: how to fix a broken door lock, symptom by symptom.
The lock is stuck or jammed
The key will not go in, will not turn, or the deadbolt will not slide home. Grit and worn pins in the cylinder cause the first two; a door that has sagged or swollen in humid weather causes the third, and we see a lot of both in pre-war walk-ups and brownstones. A stuck lock forced with the wrong key often becomes a snapped key, so stop before you get there. Guide: door lock stuck or jammed, fixes by symptom.
The knob or lever will not lock
The push button or thumb-turn will not stay set, or the latch never reaches the strike plate. Loose mounting screws let the knob rotate on its spindle so the button cannot seat; a latch that misses the strike means the door or hinges have moved. Either way the door is not really locked, so treat it as urgent. Guide: fixing a door knob that will not lock.
The cylinder spins in the door
The whole cylinder turns with the key instead of holding still. On a cylindrical lock that points to a broken cam or tailpiece behind the cylinder; on a mortise lock it is usually the cylinder set screw at the door edge working loose. Tightening the set screw is a quick fix; a broken cam means a new cylinder. Guide: how cylindrical door locks fail and what a fix involves.
The round knob is loose, wobbly, or worn out
The knob rocks in your hand, the latch is sluggish, or the whole assembly rattles. On the tubular and round knob locks common on interior and secondary doors, that is worn internal parts or a loose rose. Guide: repairing a round door lock.
Mortise or cylindrical? It changes the repair
Tell us which you have when you call and we arrive with the right parts. A mortise lock sits in a rectangular pocket cut into the door edge, has a large faceplate with the latch and deadbolt in one case, and is standard on older Manhattan apartment doors, brownstones, and many storefronts. It is repaired by opening the case and replacing springs, hubs, or the cylinder. A cylindrical lock mounts through two round bores, one for the knob or lever and one for the latch, and is what most newer residential and light-commercial doors use. It is repaired by pulling the knob and swapping the failed internal part or the whole chassis. High-security cylinders such as Medeco or Mul-T-Lock can be fitted to either type.
Fix or replace? Making the call
Repair makes sense when the lock body is sound and one part has failed: a cylinder, a spring, a tailpiece, a strike that needs resetting. It is the right answer for vintage mortise hardware, high-security cylinders, and locksets that match the rest of a co-op or brownstone. Replacement makes sense when the housing is cracked or rusted, the lock has failed more than once, the cylinder was damaged in a break-in attempt, or the door needs a higher security grade than the old lock can give. Whichever way it goes, we tell you before the work starts, and we do either on the spot. If the lock is past saving, that becomes a lock change.
What determines the cost is the lock type, whether a part or a full cylinder is needed, and the time of the call. Our guide to what drives door lock repair cost in NYC walks through each of those factors.

Frequently Asked Questions
Unlock our most frequently asked questions about lock repair in NYC.
Can a damaged lock be repaired, or does it need to be replaced?
Many common problems — stiff turning, a sticking key, misalignment, or a loose cylinder — can be repaired rather than replaced. Our locksmith diagnoses the root cause on-site, and often a lubrication, cylinder cleaning, or strike-plate adjustment solves it. If internal components are broken or the lock grade is too low for your security needs, replacement is the smarter investment. Either way, we give you both options with clear pricing.
My lock was damaged in a break-in — what should I do?
Call Golden Key Locksmith NYC right away at (212) 204-1655. We provide 24/7 emergency lock repair and replacement across all five boroughs. After a break-in we assess every entry point, repair or replace damaged locks and door frames, and recommend upgrades to prevent a repeat. We can also provide documentation suitable for your insurance claim.
Why is my key hard to turn in the lock?
A stiff or hard-to-turn key usually comes down to one of three things: a worn or bent key, debris inside the cylinder, or a dry or corroded mechanism. Try a graphite-based dry lubricant first — never WD-40 inside a lock. If it does not improve, call us; a cylinder cleaning or a fresh key cut from the original usually fixes it. Forcing the key risks snapping it off inside the lock, so it is best addressed early.
Do you offer lock repair after showroom hours?
Yes. Our showroom at 328 Columbus Ave is open Mon–Fri 8:30 AM–5:00 PM, and we offer mobile emergency locksmith service after hours without an added fee, 24/7, 365 days a year. A technician typically arrives within 20 to 30 minutes depending on the time of day and traffic.
