What Smart Lock Installation Actually Involves on a Chicago Door
A keypad or connected lock isn't simply bolted over your existing hardware. Our trained technicians begin every job by evaluating the door itself — thickness, material (hollow-core, solid wood, steel-clad), backset measurement, and the condition of the existing bore holes and strike plate pocket. Chicago's older greystone and vintage brick buildings frequently have non-standard door prep, warped frames from decades of lake-effect weather cycles, or misaligned strikes that need correction before a new lock will function reliably. Skipping that assessment and forcing a smart lock onto a poorly prepared door is the single most common reason homeowners end up with a lock that binds, misreads codes, or fails to latch fully.
Once the door is verified, our technician selects the appropriate mounting format. Most residential doors take a cylindrical smart deadbolt or a smart lock door knob/lever combo that drops into the existing 2-1/8" bore. Older Chicago apartment doors and many commercial entries, however, use a mortise smart lock format — a rectangular pocket cut into the door edge that houses the full latch, deadbolt, and cylinder mechanism in one unit. Mortise lock retrofits require precise measurement, sometimes minor door-edge work, and careful strike realignment; our experienced crew handles this routinely on the courtyard buildings and mixed-use storefronts throughout the Edgewater, Andersonville, and Rogers Park corridor.
