Lock Installation Service in NYC

Whether you are replacing a worn lock, fitting out a new door or planning a renovation, start with clear photos of the existing hardware and door edge. Include the lock brand or model when available. Deadbolts, mortise locks, rim locks and cylindrical locks use different fittings. Ask the provider to confirm the required door preparation, compatible hardware and any building requirements before work begins.

Installation requests can include: • Deadbolts suited to the door and its required exit function • Mortise locks, found in many NYC apartment buildings • Rim locks on older brownstone and walk-up doors • Cylindrical knob or lever locks • High-security cylinders and lock systems • Supplemental apartment locks where permitted • Gate and storage locks • Electronic or smart locks after a compatibility check Confirm the exact hardware and required approvals. Do not add a lock that prevents a required exit from opening safely.

The estimate depends on the lock, door material, existing cutouts, required preparation and whether hardware is included. Tell the provider how many locks you need and whether you already bought them. Review the service fee, labor, parts and applicable tax in the app before confirming. If the door needs additional work, review that proposal and its revised price before approving it.

Consider having the hardware assessed if: • A lock is worn, loose or difficult to operate • The door or lock was damaged during a break-in attempt • Keys were lost, stolen or shared with someone who should no longer have access • You are moving and want to review who has keys • You need different access features or security hardware • Your building or insurer has specific requirements A change of keys may be enough when compatible hardware is sound. Ask whether rekeying, repair or replacement fits the actual problem.
