Jimmy Proof Lock Installation
The Jimmy Proof lock — also called a rim lock or vertical deadbolt — is the most common lock on Brooklyn and NYC apartment doors. It mounts on the inside surface of the door frame, making it extremely resistant to forced entry. Unlike a standard deadbolt that goes through the door, the jimmy proof interlocks vertically, making it nearly impossible to pry open.
Why Brooklyn Residents Choose This Service
Nearly every pre-war apartment building in Brooklyn uses jimmy proof locks as the primary security hardware. When you move into a new apartment, change tenants, or upgrade an aging lock, a jimmy proof replacement is almost always the right call. We carry Segal, Marks, and Kaba jimmy proof locks — the three brands most common in Brooklyn buildings.
