Lockouts, rekeys, mortise repairs on pre-war doors, panic bars on storefronts, car keys cut and programmed at the car: the photos and dates on our recent jobs page show what the work looks like. Call or text (917) 495-1990.
The hardware we install most often: Medeco M4 and Mul-T-Lock MT5+ cylinders where key control matters, Grade 1 mortise locks on doors that get slammed a hundred times a day, and jimmy-proof deadbolts on Brooklyn walk-ups. City doors take abuse, so we fit hardware that can take it.
Residential Locksmith
From a first-apartment rekey to a full mortise lock replacement on a pre-war door, our residential work covers every kind of New York home — walk-ups, brownstones, co-ops and high-rises. We handle lock changes, deadbolt upgrades and home lockouts, and we work within building and co-op rules so new hardware goes in without a fight with the board.

Commercial Locksmith
Storefronts, offices and buildings across the city rely on us for master key systems, panic bars and exit devices, high-security cylinders and lock changes when a space turns over. We coordinate with property managers and work around business hours so a lock job does not cost you a day of business.

Automotive Locksmith
Lost your only car key, need a fob programmed, or dealing with an ignition that will not turn? We cut and program keys at the car for most makes and model years, so a lost key does not mean a tow truck.

NYC Building Types
The doors of this city are not interchangeable, and neither is the hardware. Brownstones and pre-war walk-ups have thick wood doors cut for mortise locks — like the front door we repaired on Montague St in Brooklyn Heights in June — and narrow frames that only accept slim-profile deadbolts. Putting the wrong lock on an old door ruins both.
On the other end: in April we installed a Mul-T-Lock high-security cylinder on an apartment door and upgraded the lock on a glass entry door in a modern residential building. Doors like these often need parts a hardware store does not stock. We source them, and we match finishes — oil-rubbed bronze, satin nickel, polished brass — so the security upgrade does not fight the interior.
High-Rise & Luxury Condo Security
High-rise work is half locksmithing, half coordination. Most luxury buildings run a master key system, so we work with the superintendent to fit new locks into the building's existing keyway, and we install the self-closing hinges many buildings require on apartment entry doors.
Commercial buildings hide unusual hardware too. In April we changed a floor lock on a high-traffic entrance near Grand Central, a fitting that sits in a steel housing at the bottom of the door and bolts into the floor. When a building has unusual hardware, it helps to send someone who has worked on it before.

Smart Locks & Keypad Entry
In April we installed a keypad lock on a building entrance near Bedford Ave & N 7th St in Williamsburg and repaired the panic bar on the same door. Keypads solve a specific New York problem: keys that get copied. A tenant moves out, you delete their code. A dog walker starts, you add one. Nobody has to hand out or collect keys.
That same month we did a from-scratch smart keypad deadbolt installation, including drilling and prepping a door that never had a deadbolt. The part people underestimate is mechanical: if the bolt binds against the strike plate, the motor strains and the lock dies young. We align the hardware so the bolt glides — that is the difference between a smart lock that lasts and one that fails in a year.
Biometric & Keypad Integration
We install fingerprint locks and touchscreen keypads, and we calibrate the sensors so they read reliably — a biometric lock that works four times out of five is worse than a key. Keypad deadbolts get temporary PIN codes for cleaners, contractors, and guests, revoked the moment they are no longer needed.
For remote control we set up the Wi-Fi bridge and connect the lock to your phone, and we troubleshoot existing smart locks that misbehave. Often a "broken" smart lock is a mechanical alignment problem wearing the motor down — we fix the alignment, not just the symptom.
Safes & Deadbolt Upgrades
We install floor safes, wall safes, and freestanding fireproof units for homes and businesses, anchored into the structure, because an unanchored safe is easy to carry away. On the door side, swapping a builder-grade lock for a Grade 1 deadbolt is one of the most worthwhile security upgrades an apartment can get.
Commercial Safe Servicing
Retail businesses that handle cash daily use drop safes — rotary hopper or front-loading depository units that let staff deposit cash without opening the main compartment. We anchor them into the floor and change combinations on dial and electronic safes whenever management changes hands.
Electronic safe keypads fail — batteries die, boards glitch. When that happens we get the locked safe open, replace the keypad if it needs it, and service the locking bolts and relock mechanism so the door does not jam at the worst possible moment.

Frequently Asked Questions
Is Sunny Locksmith licensed to operate in NYC?
Yes. Sunny Locksmith is an NYC-licensed locksmith, DCWP license #2096389-DCA. The number appears on our invoices and on this site, and we are insured.
Can you work on historic pre-war doors?
That is a large share of what we do. Pre-war and brownstone doors use mortise locks, and we repair the original mechanism or fit a new cylinder — including Medeco and Mul-T-Lock high-security cylinders — into the existing mortise body, so the door keeps its original face. Recent examples from the Upper West Side and Sunset Park are on our work page.
Does Sunny Locksmith service all five boroughs?
Yes, all five, plus nearby Nassau County and Westchester.
What high-security lock options do you install?
Medeco M4, Mul-T-Lock MT5+, and Grade 1 mortise hardware. Which one fits depends on the door and what it needs to resist — keys getting into the wrong hands, forced entry, or both — and we will tell you honestly which one your door actually needs.
What is the difference between lock rekeying and lock replacement?
Rekeying changes the pins inside your existing cylinder so old keys stop working — the hardware stays on the door. Replacement means new hardware entirely. If your lock is in good shape and you just need the old keys to stop working, rekeying is usually the simpler job.
Does Sunny Locksmith handle commercial master key systems?
Yes. We design and install master key systems for commercial buildings of all sizes, and we rekey and expand existing systems when tenants or staff change.
Can I schedule non-emergency work?
Yes. The phone is answered 24/7 for emergencies and scheduled work alike, and most jobs are finished in a single visit.
