Residential Locksmith NYC — 24/7 Home Lock Services

Apartment doors, brownstone entries, pre-war mortise locks, and smart keypads — residential locksmith work in NYC is mostly about doors that have been abused for decades and keys that too many people copied. Sunny Locksmith handles home lockouts, lock changes, rekeys, deadbolts, and high-security upgrades across Manhattan, Brooklyn, and Queens. Recent jobs — mortise replacement at 72nd St & Broadway, deadbolt in Crown Heights, mailbox lock in Washington Heights, apartment lock change at Flatbush Ave & Atlantic Ave — are on our work page. Licensed NYC #2096389-DCA. Call (917) 495-1990.

What We Do for Homes and Apartments

House lockouts 24/7 — pick first, drill last. Lock changes and rekeys when you move in or lose keys. Deadbolt installation where there is only a knob. Medeco and Mul-T-Lock when you need keys that cannot be copied at a kiosk. Smart keypads when you want codes instead of copies. Mailbox locks on the same visit. One van, whole apartment secured.

Pre-War Mortise Doors

A large share of NYC housing stock runs mortise locksets in deep door pockets — UWS at 72nd St & Broadway, Sunset Park at 4th Ave & 36th St, Mill Basin at Avenue U & East 66th St on our work page. Replacement has to match the pocket; we measure first and carry common sizes. Rekey when the body is sound; change when it is not.

Moving In — the Non-Negotiable Rekey

You do not know how many copies of your apartment key exist. The Flatbush Ave & Atlantic Ave job in April was a full change because hardware was weak; when cylinders are healthy, rekey achieves the same key control for less. Either way, do it before you unpack.

Interior and Secondary Doors

Bedroom lockouts, basement doors, garage man-doors — see garage lock repair — and cabinet locks for medicine and documents. Jimmy-proof locks for apartment doors off public hallways — we installed one at Clark St & Henry St in Brooklyn Heights in June.

Landlords and Multi-Family

Turnover rekeys, Grade 1 hardware on building entries, small master key systems for supers. Eviction lock changes with proper documentation. We key units alike or distinct per your policy.

Co-ops, Condos and Building Management

Building keyways, hardware finish requirements, and super coordination — we deal with co-op boards regularly when installing Medeco, Mul-T-Lock, or smart locks. Mailbox banks in lobbies, package room access, and basement storage cages often get handled on the same visit as the apartment door. Landlords with multiple units call us for turnover rekeys keyed alike or master-keyed for super access.

Emergency vs. Planned

Locked out at midnight: emergency dispatch. Planning a upgrade: same technicians, scheduled window. Non-destructive opening at Delancey St & Essex St in April is the standard we aim for on lockouts — intact lock, working old key, unless you want it changed.
