Master Key System in Manhasset Hills, NY

A master key job is priced by door count and hierarchy depth, not a flat rate. A simple setup, one master key opening a handful of similar locks, sits at the low end of $195 to $850+.

A layered system, where a grand master opens everything, sub-masters open specific floors or units, and individual keys open only one door, costs more because each cylinder has to be pinned to match its place in that hierarchy. Before any cylinder is touched, the technician gives you the actual number for your property, not a range.

Manhasset Hills is a small, entirely single-family CDP with no LIRR station, so every visit is a car trip in on Marcus Avenue, New Hyde Park Road, Denton Avenue, or Shelter Rock Road depending where the property sits. Call the dispatch line and a dispatcher who understands locksmith work takes down the job and your number.

The nearest available technician calls you back within a few minutes to talk through the property, how many doors and units are involved, and to quote the job before anything is scheduled. That local routing is how the technician reaches a property near Shelter Rock Road or Lake Success inside the 15 to 30 minute window instead of dispatching from farther out.

Have a door count and a rough idea of the hierarchy you want ready: who needs a master that opens everything, who needs access to only certain units or floors, and how many individual keys you'll need cut. If it's a multi-unit or commercial building, having a way for the technician to get to each door, whether that's you, a super, or a property manager on site, keeps the walkthrough from stalling.

For larger jobs the technician may need to come back with cylinders or blanks matched to your existing hardware, so knowing your current lock brand in advance can save a second trip.
