What a Post-Burglary Emergency Lock Change Actually Involves
The phrase 'lock change' sounds straightforward, but after a burglary the scope is often broader than a simple cylinder swap. Our technicians begin with a door-and-frame assessment: we check whether the strike plate was ripped from the jamb, whether the door itself is structurally compromised, and whether secondary locks — chains, surface bolts, secondary deadbolts — were also defeated. Only after that walkthrough do we confirm the exact work required. For most New York apartment doors, this means replacing or re-pinning a mortise lock body, installing a new high-security cylinder, and reinforcing the strike plate with a heavy-gauge box strike and three-inch screws that anchor into the wall stud rather than just the thin door casing.
In buildings along Second Avenue or in the Murray Hill corridor where older prewar construction is common, mortise lock hardware is standard — these are the large, rectangular lock bodies set inside the door edge rather than surface-mounted. Our technicians are experienced with the full range of mortise lock configurations used across New York's housing stock, including Marks, Yale, and Corbin Russwin-style bodies, and we stock replacement units on our vehicles. We work to complete every replacement damage-free where the existing door and frame allow, preserving your door's finish and avoiding unnecessary drilling.
