Lock Change NYC

A lock change in NYC means the full swap — new hardware, new keys, every old copy instantly worthless — and Top Notch Locksmith & Security installs new locks 24/7 in all five boroughs, often during the same visit as an emergency call. It's the decisive option on our locksmith services list; if your hardware is fine and key control is the only problem, rekeying costs less and gets you the same fresh start.

Lock Changes After a Break-In

A forced lock doesn't get a second chance. If the cylinder was snapped, drilled, or pried, its internals are compromised even when it still turns, and trusting it overnight is a bet you don't want. Our emergency locksmith line runs 24/7 for exactly this call: the technician removes the damaged lock, installs new hardware from the truck, and reinforces the strike plate if the frame took abuse. Most people upgrade in this moment rather than replacing like-for-like — the lock that just failed has made its argument. You sleep behind a working, stronger door the same night.

Upgrading to Medeco and Mul-T-Lock High-Security Locks

Standard cylinders do an adequate job until someone decides to test them. Medeco and Mul-T-Lock cylinders raise the bar in three ways: they resist picking, they resist drilling, and their keys are cut on restricted blanks — so a roommate, contractor, or ex can't duplicate one at a hardware shop. For street-facing doors, gates, and any apartment where you don't control who has touched the keys over the years, the upgrade pays for itself in not wondering. Our high-security locks page breaks down the differences; we stock both brands and install during the same visit.

Landlord Turnovers and Property Changes

Owners and managers call us for the planned version of this work: lock changes between tenants, standardizing hardware across a building so every unit takes the same parts, setting up keyed-alike groups or master systems that make management sane. Replacing scattered, mismatched locks with one consistent line cuts future maintenance — one spare cylinder in the office covers any door. We quote per-door pricing transparently before work begins, document what's installed where, and leave you a key map instead of a mystery. For partial-building jobs, we'll flag which existing locks are healthy enough to rekey rather than replace.

Common Questions

Should I change my locks or rekey them?

Change them if the hardware is damaged, worn, or you're upgrading security. Rekey if the lock is healthy and you only need old keys to stop working. We quote both before starting.

How quickly can locks be changed after a break-in?

We dispatch 24/7 and stock hardware on the truck, including Medeco and Mul-T-Lock, so most break-in changes finish in a single same-day visit.

Do I pick out locks ahead of time?

You can, but you don't need to — the technician brings standard and high-security choices and walks you through them at the door.

What does a lock change cost?

You get a transparent quote before work begins — no hidden fees, whether it's one door or a whole building.
