Deadbolt Installation: Choosing the Right Lock for Your Door
Not every deadbolt fits every door, and selecting the wrong hardware can leave gaps in your security even after a professional installation. Single-cylinder deadbolts — operated by a key outside and a thumb-turn inside — are the most common choice for residential entry doors in Bergen County homes. Double-cylinder models, which require a key on both sides, are sometimes chosen for doors with glass panels nearby, though they raise egress considerations that our technicians will walk you through honestly. For metal apartment doors and older Lodi multi-family buildings, a jimmy proof deadbolt installation is often the smarter path: these surface-mounted interlocking bolts are designed so that the bolt and strike plate physically interlock, making pry attacks far less effective than on a standard mortised deadbolt.
For higher-end residential applications or any commercial door, a mortise lock is frequently the superior solution. Unlike a cylindrical deadbolt that bores through the door face, a mortise lock body is recessed into a pocket cut into the door's edge, distributing force across a much larger area of the door frame. Our technicians perform mortise lock installations on steel-frame storefronts, office suites, and solid wood doors throughout Lodi — and because we carry the equipment needed for precision pocket routing on-site, the job can be completed in a single visit.
