Changing locks in Manhattan isn't as straightforward as in other boroughs. The majority of Manhattan apartments — especially those built before 1940 — use mortise locks recessed into the door edge, not the standard cylindrical deadbolts you'd find in newer construction. This means a Manhattan lock change often involves matching the exact mortise body dimensions, backset, and trim style to fit your existing door preparation. Our technicians carry an inventory of mortise lock bodies, cylinders, and trim sets specifically for Manhattan's building stock.
Manhattan co-ops and condos frequently have building-specific lock requirements. Many co-op boards mandate specific lock brands or require that locks meet certain security grades. Some buildings require that the superintendent or management company approve lock changes in advance. We're familiar with these protocols and can advise on compliance before beginning work. For newer luxury buildings, we install and rekey Medeco, Mul-T-Lock, and Abloy high-security cylinders.
Standard cylindrical deadbolt replacement runs $100–$180. Mortise lock replacement in pre-war apartments is $180–$350 due to the specialized hardware and labor involved. We provide exact pricing after inspecting your door.
In most cases, yes. We carry common mortise trim styles and can match the handle, knob, and escutcheon plate to your existing door preparation. For rare or vintage trim, we may need to order parts, but we can install a functional lock immediately and return to swap the trim.
Many do. Some co-op boards require specific lock brands, minimum security grades, or superintendent notification before changes. We're familiar with common building policies and can advise you on compliance before starting work.
