What Makes High-Security Lock Installation Different From Standard Door Lock Installation
Not every lock installation is equal. A basic door lock installation — swapping one knob or deadbolt for another — can often be done with a drill and a screwdriver. High-security commercial lock installation is a different discipline entirely. It begins with a site assessment: our technician evaluates door material, frame condition, hinge placement, and the existing prep (the cutout and bore pattern already in the door) before recommending hardware. Commercial-grade mortise lock bodies, for example, require a deep rectangular pocket routed precisely into the door edge. Get the dimensions wrong and the lock binds, the latch doesn't retract cleanly, or the strike plate misaligns — any of which defeats the purpose of upgrading in the first place.
Restricted-key systems add another layer of complexity. Unlike standard keys that can be duplicated at any hardware store, restricted-key cylinders are manufactured with patented keyways and tight tolerances. Duplication requires written authorization and is only available through authorized channels, which means a terminated employee cannot simply walk into a shop and copy a key. Brands like Medeco, Mul-T-Lock, and ASSA ABLOY produce cylinders specifically engineered to resist picking, bumping, and drilling — and installing them correctly requires precise cylinder alignment and torque specs that our trained technicians follow on every job.
