Master Key System in Lattingtown, NY

A Gold Coast estate lot is rarely a single building. Main house, guest quarters, stable or barn, pool house, and a detached garage each might need their own lock, but not their own separate key ring.

A basic hierarchy for a house with two or three outbuildings runs toward the lower end of $195 to $850+, while larger properties with several structures, multiple staff tiers (owner, family, groundskeeper, cleaning service), and higher-security cylinders push toward the top. The technician who calls you back will ask how many doors and how many access levels before quoting, so have that count ready.

Lattingtown has no LIRR station and long private driveways are common, so technicians here rely on gate codes, call boxes, or a phone call as they turn onto Lattingtown Road, Bayville Road, Frost Mill Road, or Feeks Lane rather than guessing at a house number from the road. Tell the dispatcher which of those roads your driveway sits off and whether there's a gate, keypad, or caretaker who needs to let the technician in.

Expect the technician on site in 15 to 30 minutes of the callback confirming the visit.

Walk the property first and count doors, noting which ones need to be on the master (owner access to everything) versus a sub-master (staff access to specific buildings) versus a standalone key. If you already have keyed-alike hardware or a particular lock brand installed, mention it on the callback since it affects whether existing cylinders can be re-keyed into the new hierarchy or need replacing.

Gate access instructions matter as much as the lock count for a property this size.
