Lock Change Service in Mill Basin & Marine Park, Brooklyn

New locks professionally installed on any door: quality hardware, proper fit and smooth operation.

Whether your locks are worn out, outdated or simply not secure enough, we remove the old hardware and install new locks that fit properly and operate smoothly. We carry common residential sets and can source specialty hardware when you need it.

What’s included

  • Removal of old locks and clean installation of new hardware
  • Knob sets, lever handles, deadbolts and combination sets
  • Door prep: re-boring and repairing worn strike plates
  • Keyed-alike options so one key fits every door
  • Advice on grades and brands that suit your budget

What to expect

A new lock is only as secure as its installation. A loose strike plate, a misaligned latch or short screws can make a strong lock easy to defeat. We check the door, frame and strike area every time and correct problems as part of the install.

If you are not sure what to buy, we walk you through the options in plain language, from standard residential grades to higher-security cylinders. You decide, and we install. If your current locks are in good shape, we will tell you when a rekey is the cheaper fix.

How long does a lock change take?

Most single-door installs take under an hour. Multiple doors or door repairs can take longer.
