Locksmith & Door Hardware
Downtown Doors & Security handles locksmith and door hardware work across Brooklyn and Manhattan — lock repair and rekeying, deadbolt and smart-lock installation, master key systems, and hardware like closers, hinges, and panic bars. We make sure your doors lock securely and the right people have access.
This covers the lock and hardware side of a door: repairing or rekeying locks, installing deadbolts and smart locks, setting up master key systems for buildings, and replacing the closers, hinges, panic bars, and strikes that let a door function and lock properly.
We serve homeowners, landlords, and businesses — from rekeying a single apartment after a tenant change to setting up a master key system for a multi-unit or commercial building.

Frequently asked
Can you rekey my locks instead of replacing them?
In most cases, yes. If your existing locks are in good condition, rekeying is a faster, lower-cost way to make sure old keys no longer work — ideal after a move or tenant change.
Do you install smart locks and keypad entry?
Yes. We install smart locks, keypad, and keyless entry for homes and businesses, and can integrate them with access control where appropriate.
