Locksmith & Security in Brooklyn Heights
In Brooklyn Heights, Downtown Door Repair & Security repairs and restores the historic entry doors, brownstone vestibules, and apartment doors the neighborhood is known for — along with locksmith and security work for its townhouses and small businesses.
Serving Brooklyn Heights
Brooklyn Heights is dense with landmarked brownstones and pre-war co-ops, so much of the work here is careful repair and hardware matching on older doors and frames rather than wholesale replacement — plus rekeying and buzzer/intercom entry for multi-unit buildings.
Across Brooklyn Heights, the most common calls are door repair and re-alignment on high-use entries, lock rekeying and lock changes after a move or tenant turnover, and storefront and commercial door work — closers, pivots, panic hardware, and glass — for the neighborhood's shops and offices. We also install and service intercom and buzzer entry, access control and electric strikes, and security cameras for Brooklyn Heights's apartment buildings and businesses, and provide 24/7 emergency door repair when a door won't lock, won't close, or has been forced in a break-in.
Whether it's a single sticking apartment door, a fire door that needs to pass inspection, a storefront gate that won't roll, or a full building access-control and camera system, Downtown Door Repair & Security handles it across Brooklyn Heights and the rest of Brooklyn — licensed, insured, and usually the same day.

Working in Brooklyn Heights — FAQ
Can you rekey or replace locks on a landmarked brownstone door without damaging it?
Yes — this is the bulk of our Brooklyn Heights work. On landmarked brownstones we rekey or replace the cylinder and internal hardware while keeping the original escutcheons, rosettes, and mortise casework intact, so nothing changes on the street-facing side. Our main office is at 170 Hicks St, so a tech is minutes away.
Do you service buzzer and intercom entry in pre-war co-op buildings?
We repair and replace intercom and buzzer panels in Brooklyn Heights' pre-war co-ops regularly — from fixing dead door-release strikes on a single unit to replacing a full lobby panel with an audio/video or smartphone-based system, coordinated with the board or managing agent.
Where is your Brooklyn Heights office?
170 Hicks St, Brooklyn, NY 11201 — (347) 514-8770. It's our original location and main office: locksmith-led, with door supply and repair and security-system installation from the same crew, and it still handles most of the brownstone-Brooklyn and Downtown Brooklyn work.
