Master Key System in Old Bethpage, NY

Cost depends on two things: how many doors are on the system and how many tiers the key hierarchy needs. A simple setup, one master key plus a handful of change keys for a small office or small multifamily building, sits toward the $195 low end.

A property with multiple access tiers, building master, sub-masters for different units or departments, and individual change keys, runs higher, up to $850+. When the technician calls back, they'll ask for the door count and how you want access split (by floor, by tenant, by department) so the quote reflects the actual job, not a guess.

Old Bethpage has no LIRR station and is car-dependent, so technicians drive in from the surrounding area rather than relying on transit-adjacent scheduling. The hamlet sits off Round Swamp Road, Old Country Road, Bethpage-Sweet Hollow Road, and the Long Island Expressway (I-495), which keeps drive times predictable for a dispatcher routing to the nearest available tech.

Typical arrival on a scheduled visit is 15 to 30 minutes out. Have the building address and best on-site contact ready when the technician calls back so they can confirm access before heading over.

Walk the property and count exterior and interior doors that need to be on the system, note which doors should share a key (say, all units on one hallway) and which need to stay isolated. If you have existing keyways, cylinders, or a prior locksmith's key chart, have that on hand, it speeds up the hierarchy design and avoids re-keying doors that don't need it.

RC Locksmith Nassau County has operated in the county since 2009 and dispatches locally, so the technician who calls you back knows the area and can plan the visit around your property's actual layout rather than a generic template.
