Residential Locksmith BrooklynBrownstones, Apartments & Townhouses

Brooklyn homes have personality, and that personality shows up in their locks. A 1890 Park Slope brownstone needs a totally different approach than a 2024 Williamsburg condo. SwiftLocksmith specializes in Brooklyn residential lock work because we live here, work here, and have installed every common Brooklyn lock from antique mortise to August Wi-Fi smart locks.

Common Brooklyn residential jobs we do every day

• Move-in rekey — your new place; 24-48 hours after closing the previous tenant's keys are useless. $85-$150 for a typical 2-cylinder apartment.
• High-security lock upgrades — Medeco Maxum, Mul-T-Lock MT5+, and Schlage Primus for brownstones, garden-floor units, and street-level apartments.
• Smart lock installation — August Wi-Fi, Yale Assure, Schlage Encode, and Aqara U200 installed and configured. We handle co-op and HOA documentation.
• Brownstone restoration — repair or restore antique mortise locks while adding modern security.
• Emergency lockouts — 24/7 damage-free entry with 20-30 minute response.
• Window and patio-door locks — sash locks, key-operated locks, and reinforced pin locks for ground-floor units.

What it actually costs

Standard apartment rekey of 2 cylinders: $85-$150 all-in. Single deadbolt installation: $125-$250 depending on hardware. Smart lock install with hardware: $200-$450 plus the cost of the lock. High-security cylinder upgrades: $225-$500 per door. We always give a written quote before any work begins — Brooklyn customers hate surprises and so do we.

Co-op, condo & landlord-friendly

We email Certificates of Insurance to building management before arrival, work within building access hours, and can document any modifications for your co-op or condo board. Brooklyn property managers from Bay Ridge to Greenpoint use us as their preferred locksmith vendor.

Smart locks that actually work in Brooklyn buildings

Not every smart lock works in every Brooklyn building. Wi-Fi-only locks struggle in old brownstones with thick plaster walls. Some condo doors are too thick or too thin for off-the-shelf smart locks. We assess your door and your Wi-Fi situation before we recommend a model — and we install the model that actually fits, not whatever the store had on sale.
