Deadbolt Installation & Upgrade: Choosing the Right Lock for Your Door
Not every deadbolt suits every door, and matching the hardware to the door type, frame material, and threat level is where trained expertise matters most. A standard single-cylinder deadbolt works well on most residential doors where the interior turn-piece is accessible, but double-cylinder versions are worth considering on doors with adjacent glass panels. For doors with metal frames — common in older Queens apartment buildings and multi-family homes — a jimmy proof deadbolt installation is often the smarter choice. The jimmy proof design interlocks with a surface-mounted strike rather than projecting a bolt into a frame, making it extremely resistant to the prying and spreading attacks that standard deadbolts can fail against.
Mortise lock installation takes security a significant step further, particularly for commercial properties. A mortise lock is set into a pocket machined into the door edge, creating a much larger and more structurally integrated assembly than a bored cylindrical lock. Because the hardware engages the door slab itself rather than just a surface-mounted strike, mortise lock systems are exceptionally hard to kick in or manipulate. Our commercial locksmith team installs and services mortise locks on office doors, retail storefronts, warehouses, and multi-tenant entry points throughout Queens. If your business is on a high-traffic corridor — think Main Street Flushing or the commercial strips near College Point Boulevard — a mortise lock upgrade is a conversation worth having with our technicians.
