What Forced Entry Actually Does to Your Locks and Doors
Most people picture a kicked-in door and think only the lock needs replacing. In practice, the damage from a forced entry spreads across multiple components simultaneously. A door knob lock that has been forcibly turned or wrenched typically shows internal cam damage, a broken spindle, or a sheared retaining screw — none of which is visible until the knob is removed and inspected. More significantly, the door frame itself absorbs the majority of the force during a kick-in attack. The wood around the strike plate compresses and splits, leaving a gap that no new lock can bridge on its own. If the frame is not rebuilt and reinforced, even a brand-new deadbolt will fail just as quickly the next time.
Mortise lock assemblies — the rectangular lock bodies that sit recessed inside the edge of the door and are standard throughout New York City's older pre-war apartment buildings and commercial storefronts — are especially complex after a forced entry. The pocket machined into the door must remain square and intact for the lock body to seat properly. When the door is torqued during an attack, the pocket can rack out of alignment, and the internal levers or cylinders of the mortise lock can shear. Our technicians are specifically trained in mortise lock diagnosis, repair, and full replacement across a wide range of grades and configurations, including high-security options from brands like Schlage that meet or exceed NYC Multiple Dwelling Law requirements.
