Master Key System in Matinecock, NY

A master key system is priced by door count and hierarchy depth, not a flat fee. A simple two-tier setup, owner key plus staff keys, on a main house and garage runs toward the lower end.

A layered system across a main house, guest house, stable, and gatehouse with separate access for groundskeepers, housekeeping, and property managers costs more because each tier needs its own pinning and key cut. The callback quote covers exact door count and how many key levels you want before any cylinders are touched, so you know the number before committing.

Matinecock is 5-acre minimum zoning with gated homes and long private drives off Piping Rock Road, Duck Pond Road, and Chicken Valley Road, and there's no LIRR stop in the village itself, so every visit here is a car trip regardless of where the technician starts from. If your property has a gate code, keypad, or an intercom that needs to be buzzed, give that to the dispatcher up front and it gets passed to the technician with the job, which keeps them from idling at the entrance while a call gets sorted out.

Expect the technician in 15 to 30 minutes of the callback.

Walk the property first and count every door that needs to be on the system: main house exterior doors, guest house, stable or barn, gatehouse, garden shed, garage. Decide who needs access to what, owner, family, live-in staff, groundskeeper, contractors, since that shapes how many key tiers get cut.

If any doors already have mismatched hardware from different eras of the house, mention it on the callback so the technician arrives with the right cylinders rather than needing a second trip.
