Locksmith Washington Heights — 24/7 Licensed Service
Washington Heights is built almost entirely from one thing: six-story elevator apartment houses put up between the two world wars, with Art Deco co-ops filling the blocks along Fort Washington Avenue. Ninety years of tenants have passed through those apartment doors, and the locks show it. Sunny Locksmith works the neighborhood from Dyckman down to 155th, at any hour, under NYC License #2096389-DCA. Call (917) 495-1990.

The Apartment Door Is Usually Older Than Everything Around It
Walk into a rehabbed apartment in the 10032 or 10033 blocks and the kitchen may be five years old while the entry door is the one the building opened with. Those doors are narrow, solid, and carry a mortise lock body set into a pocket cut for that specific lock. Decades of repainting have thickened the edges, the strike has been moved and re-moved as the frame settled, and the cylinder may have been changed a dozen times while the body underneath never was.
That history changes the work. Dropping a modern deadbolt into an old mortise pocket is not a repair, it is a hole in a door. The correct job is either servicing the existing body — cleaning and re-pinning it, replacing worn internal parts, correcting the strike alignment — or fitting a modern mortise lockset sized to the pocket that is already there. Both keep the door intact, which matters when the door belongs to the building rather than to you.
Turnover Means Rekeying, Not Replacing
The single most useful job in this neighborhood is also the least dramatic. When a tenant moves in, nobody can say how many keys exist to that apartment. Previous tenants, their relatives, a super who left in 2011, a contractor who did the bathroom — the honest answer is that the count is unknown, and unknown is the problem.
Rekeying resets it. We change the pinning inside the cylinder you already have, so the old keys stop working and you get a fresh set. The lock stays, the door stays, and nothing about the apartment looks different afterwards. For a two-family house or a building where one person manages several units, we can key several apartments to a single management key while each tenant’s key opens only their own door.
Art Deco Buildings and Their Original Hardware
The co-ops along Fort Washington Avenue and Cabrini Boulevard still carry lobby and vestibule hardware from the 1930s: heavy brass pulls, original escutcheons, doors with proportions no catalogue sells today. Boards in these buildings generally want the look preserved and the function modernised, which is a solvable problem. Modern cylinders can be fitted behind original trim, and worn Deco hardware can often be repaired rather than discarded. Tell us up front if the building has rules about appearance and we will work to them.
168th Street Runs on a Different Clock
The medical centre at 168th and Fort Washington means a large share of the neighbourhood works nights and rotating shifts. A meaningful number of our calls up here come in between midnight and six, from people finishing a shift rather than starting one. Dispatch is staffed at those hours specifically because of neighbourhoods like this one.
Getting to You on These Hills
Between 181st and Broadway the streets are steep, narrow, and parked solid. It helps enormously if you can tell us the cross street, whether the building has a service entrance, and whether there is a super on site. That detail shortens the walk from the van to your door more than anything else we can do on our end.

Washington Heights Locksmith — FAQs
My landlord changed the locks. Can you let me in?
We open doors only for people who can show they are authorised to be there — a lease, a photo ID matching an address, or a building representative confirming it. A landlord locking out a tenant without a court order is a legal matter rather than a locksmith one, and we will point you to the right place instead of opening the door.
Should I rekey when I move into an apartment here?
Yes. It is the standard way to restore key control, and in buildings of this age the number of keys in circulation is genuinely unknown. Check your lease first — most permit it as long as the management gets a copy of the new key.
Can you fix the old mortise lock instead of replacing the door hardware?
Usually. Mortise bodies were built to be serviced, and many failures are worn parts, dried lubricant, or a strike that has drifted out of alignment. If the body is beyond repair we fit a modern lockset sized to the existing pocket so the door is not modified.
Do you work on the building lobby and vestibule doors?
Yes, with authorisation from the building. Common-area doors belong to the co-op or the management company, so we need their go-ahead rather than an individual resident’s.
Is anyone actually available overnight up here?
Yes — dispatch runs 24 hours a day, every day. Given the shift patterns around the medical centre, overnight calls in this neighbourhood are routine for us.
