Install house locks NYC — adding a lock where none exists
Plenty of NYC doors have only a passage knob — no deadbolt at all. Adding one means boring the door, mortising the strike, and reinforcing the jamb so the bolt has something solid to throw into. We do the carpentry cleanly, match the finish to your existing hardware, and leave the door looking like the lock was always there.
Choosing hardware for a New York door
A solid-core brownstone door can take any deadbolt made. A hollow interior door cannot. Fire-rated apartment doors have rules about what can be drilled. We assess the door, frame, and building requirements first, then recommend hardware that the door can actually support — including high-security cylinders where they make sense.
Locks for gates, fences, and side doors
Backyard gates in Brooklyn, alley doors in Queens, basement entries in the Bronx — exterior side access is part of a home's security, not an afterthought. We install weather-rated deadbolts, gate locks, and hasps built to survive NYC winters, keyed to match your house key where possible.
Interior doors: home offices and rental rooms
A home office with client files, a room rented to a roommate, a basement you want off-limits — interior keyed locks are a quiet quality-of-life upgrade. We install keyed levers and deadbolts on interior doors with clean boring and finishes that match the rest of the home.

Install House Locks FAQs
Can you install a deadbolt on a door that has not had one before?
Yes — we drill the cross bore and edge bore, mortise the strike into the jamb, and install the deadbolt. Same-day in most cases.
Do you install locks on metal or fire-rated doors?
Yes, with the right hardware. Fire-rated doors in NYC apartment buildings have rules about modifications — we use rated hardware and proper technique so the door keeps its rating.
Can you install locks I already bought?
Yes. If you picked out hardware you like, we install it — and we tell you honestly if a piece you bought will not fit your door or is not worth installing, before any holes are drilled.
Can you put a keyed lock on an interior door, like a home office?
Yes — keyed levers and interior deadbolts are a clean install on most doors, matched to your existing finishes. Common for home offices, rental rooms, and storage areas.
