Smart Lock Installation: Choosing the Right Hardware for Your NYC Door
Not every smart lock fits every door, and in New York that mismatch happens more often than people expect. The city's housing stock spans more than a century of construction — you'll find thin hollow-core doors in newer high-rises, solid hardwood slabs in pre-war coops, and steel-clad commercial doors in ground-floor retail spaces along Broadway and Atlantic Avenue. Each scenario calls for a different approach. A standard cylindrical smart lock door knob or lever retrofit works well on most residential interior and exterior doors with a standard 2-1/8-inch bore, while a mortise smart lock is the right solution for the vast majority of New York apartment entrance doors, which were built around a mortise pocket that houses both the latch and deadbolt in a single unified case.
Getting the hardware selection wrong means gaps in security, voided warranties, and doors that simply won't close correctly. Our technicians evaluate your door thickness, backset measurement, existing strike plate condition, and frame integrity before recommending any product. We work with leading hardware lines including Schlage, Kwikset, Yale, and August, and we stock the most common mortise smart lock cartridges and conversion kits so the job gets done in a single visit. If your building's management has specific requirements — common in co-ops and condos throughout Manhattan and Brooklyn — we can verify compatibility before we ever put a drill to your door.
