What Makes Commercial Storefront Mortise Lock Service Different
A mortise door lock is not a drop-in replacement the way a residential knob set might be. The mortise pocket — the rectangular cavity routed into the door edge — must match the lock body's dimensions precisely. Chicago storefronts, particularly in older Edgewater and Andersonville buildings constructed in the early 20th century, often have non-standard door thicknesses or legacy hardware from manufacturers whose product lines have since changed. Our technicians carry a broad inventory of mortise lock bodies, trim rings, escutcheon plates, cylinders, and strike plates so we can match or upgrade existing hardware without forcing you to change out the entire door frame. When an exact match isn't available, we can adapt compatible components — reaming the mortise pocket to spec or fitting a conversion plate — always aiming for a damage-free result.
A full commercial storefront mortise lock service call typically covers: diagnosis of the failed component (cylinder, cam, case, lever handle, or thumb-turn), sourcing the correct replacement parts from our vehicle stock, removal of the old assembly, precise installation and alignment of the new hardware, cylinder rekeying if required, adjustment of the latch and deadbolt throw to align flush with the strike, and a final function test under load. We also document the key bitting on file for your records. That end-to-end process is what separates a qualified commercial door locksmith from a general handyman with a screwdriver.
