New York homes come in every shape — pre-war walk-ups, Brooklyn brownstones, Queens two-families, doorman condos, and everything between. Our residential locksmith team handles lock changes, rekeys, deadbolt installation, smart lock setup, mailbox locks, storage locks, and full door hardware replacements.
If you just bought or rented a home in NYC, rekey or change the locks before your first night. You have no way to know how many copies of the old key are out there.
Pre-war walk-ups in the East Village, brownstones in Park Slope, two-family homes in Astoria, doorman co-ops on the Upper West Side, and new condos in Long Island City all have different doors, frames, and hardware. Our residential locksmith team carries the cylinders, deadbolts, and mortise parts that NYC housing stock actually uses, so most jobs finish in one visit.
The most requested upgrades are a Grade 1 or Grade 2 deadbolt on the entry door, a high-security cylinder that resists picking and unauthorized key duplication, a smart lock for keyless entry, and a reinforced strike plate with longer screws. Each one helps deter unauthorized entry — we walk you through the options for your specific door before any work starts.
Tenant turnover in NYC never stops, and every move-out is a rekey. We handle turnover rekeys for small buildings and two-families, set up simple master systems so you carry one key per building, and keep labeled records so the next turnover is a five-minute phone call. Volume scheduling is available for portfolio landlords.
Not every residential job is a front door. We replace mailbox cam locks, service intercom door releases, rekey storage-room padlocks, and open the odd jammed window gate. The small hardware matters — a broken mailbox lock in NYC means missed checks and stolen cards, and it is a fifteen-minute fix.

If the existing hardware is in good shape, rekeying is faster and simpler. If the locks are old, worn, or you want to upgrade security, changing the locks makes more sense.
Yes. We install smart locks from August, Schlage Encode, Yale, Level, and Kwikset on NYC apartment doors, including many co-op and condo buildings — we coordinate with building management where board approval is needed.
Most NYC leases allow a lock change but require you to give the landlord or management a copy of the new key. Check your lease first — we can install the lock and cut an extra key for management in the same visit.
Pre-war buildings often have mortise locksets set into a pocket in the door, while newer construction usually has tubular deadbolts and knob sets. Our residential locksmith team services both, plus the Jimmy-proof deadbolts common in older NYC walk-ups.
Yes — mailbox cam locks are a quick residential job. If the mailbox is USPS-owned cluster box, the post office handles it; for building-owned boxes, we replace the lock and hand you the only keys.
