Master Key System in Hewlett Harbor, NY

A two-door setup for a guest house and a boat house is a very different job from a full hierarchy across a main residence, garage, and outbuildings, which is why pricing runs $195 to $850+. The technician who calls you back will ask how many doors need to be on the system and how many access tiers you want (owner, family, staff, groundskeeper) before quoting a firm number.

Waterfront properties in Hewlett Harbor often include separate structures near the water, and each additional door or building adds to the hierarchy design time, not just the hardware.

Hewlett Harbor's larger lots mean a technician may need directions to the correct entrance rather than relying on a street-facing front door, especially on properties along Harbor Road or near Hewlett Neck Road where driveways can be long or gated. When you call, the dispatcher passes your number to the nearest available technician, who calls back within a few minutes to go over access details, including gate codes or which entrance to use, so the visit itself moves quickly once they arrive within the 15 to 30 minute window that applies to the area.

Walk the property ahead of time and count every exterior door, shed, and outbuilding that should be on the master system, plus decide who needs which level of access. If you're re-keying existing locks into a new hierarchy rather than installing new hardware, have the current keys on hand so the technician can confirm what's compatible.

Property managers overseeing the job on an owner's behalf should have basic authorization ready, since master key work often involves changing who can get into a home.
