Master Key System in North Hills, NY

A master key system is priced by two things: how many doors need to be rekeyed or fitted into the hierarchy, and how many tiers of access you need above the individual door keys, for example a grand master for ownership, sub-masters for building staff, and individual keys for tenants. A small multi-unit property with a simple two-tier setup lands toward the lower end of $195 to $850+; a larger commercial building with several access levels and more doors runs higher.

The technician who calls you back will ask for your door count and how you want access split before quoting a firm number, so you know the cost before scheduling anything.

Most North Hills properties sit inside guard-gated communities like The Links, Gracewood, The Fairways, or Stone Hill, so the technician will need guardhouse clearance to get onto the property. When you call, have the gate or guardhouse contact information ready, or let the dispatcher know you'll call ahead to clear the technician's vehicle for entry.

That single step is usually what determines whether the visit starts on time, since Marcus Avenue and the surrounding private roads aren't through streets a technician can just drive up to. Once cleared, arrival typically runs 15 to 30 minutes from the confirmed appointment.

Before the technician arrives, have a rough door count ready, which doors need to be on the master (all units, common areas, mechanical rooms, etc. ), and who needs which level of access.

If you're rekeying existing locks into the new hierarchy rather than installing new hardware, note the lock brands currently on the doors if you know them. RC Locksmith Nassau County has been designing and installing these systems since 2009, dispatching a local technician rather than routing your job through a national call center, so the person quoting your price is the same one doing the work on site.
