Master Key System in Hewlett Bay Park, NY

Cost scales with door count and how many levels the hierarchy needs, a small property with two or three access tiers runs toward the lower end of $195 to $850+, while a larger layout with multiple sub-master levels (say, separate keys for a caretaker, a property manager, and ownership) runs higher. The dispatcher takes down your job details and your number when you call, and the technician who calls back within a few minutes will ask how many doors and how many access levels you're picturing so the quote matches your property before anyone drives out.

Hewlett Bay Park is a small village of large single-family lots, most at least an acre, so a technician working nearby can typically reach you in 15 to 30 minutes. Have someone available who can walk the property with the technician, since master key design depends on seeing the actual doors and existing hardware, not just a count over the phone.

If your property is one of the larger estate lots, mentioning that when the technician calls back helps them bring the right stock of cylinders.

Know roughly how many doors need to be on the system and who falls into which access tier, for example, whether a caretaker or building staff should open only certain doors while an owner or manager key opens all of them. If any doors already have existing locks you want to keep, have those on hand so the technician can confirm compatibility with the new master key hierarchy rather than replacing hardware unnecessarily.
