Master Key System in Great Neck Plaza, NY

A master key system for a single small co-op entry and a handful of unit doors sits at the low end of the $195 to $850+ range. A larger building with a super's master, separate sub-masters for storage rooms or laundry areas, and dozens of individual unit keys costs more because each level of the hierarchy has to be cut and tracked separately so a lost tenant key never compromises the levels above it.

Tell the technician on the callback how many doors and how many access tiers you need (owner, super, tenant, common areas) so the quote is accurate before anyone schedules a visit.

Call (516) 636-1712 and a dispatcher logs the job and your number, then the nearest available technician calls back within a few minutes to talk through the building's door count and quote the system. For Great Neck Plaza's dense stock of co-ops and apartment buildings off Middle Neck Road, Great Neck Road, Bond Street, and Grace Avenue, that local routing matters because the technician usually already knows the building types near Great Neck LIRR station and can plan the visit around them rather than guessing.

Have a door count and a rough sense of your access tiers ready for the callback: how many entry doors, common-area doors like laundry or storage, and how many individual units need their own key under the master. If you're the property manager or board member, confirm you have authorization to order a new key hierarchy for the building, since master key systems control who can open what across the whole property.

Existing keyway or lock brand information, if you have it, speeds up the technician's plan for the visit.
