Master Key System in Glenwood Landing, NY

The $195 to $850+ range comes down to two variables: how many doors need to be rekeyed into the hierarchy, and how many tiers of access you want (a simple building master over a handful of tenant keys costs far less than a layered system with sub-masters for maintenance, cleaning, and management staff). Property managers with multiple units on Glen Cove Road, Glenwood Road, or Shore Road often want tenant-level keys that won't open neighboring units but will open under a building master, which adds design time up front but saves money over rekeying everything again at the next tenant turnover.

The technician quotes the exact number after seeing the door count and current lock hardware, not before.

Call the number and a dispatcher takes down the property address and job details, then routes it to the nearest available technician, who calls you back within a few minutes to talk through the hierarchy you need and quote a price. For Glenwood Landing, that's typically a 15 to 30 minute arrival once the visit is scheduled.

Since the hamlet has no LIRR station of its own, if you're coordinating access for a technician arriving from off Glen Cove Road or Roslyn Shore Road, having someone on site to let them in (or clear instructions for a locked gate or shared entrance) keeps the walkthrough from stalling at the door.

Have a rough door count ready, along with any existing keying documentation if the property was master-keyed before (this tells the technician whether you're starting fresh or expanding an existing hierarchy). Know who needs which level of access: building-wide, floor or wing, or single unit, since that shapes how many key tiers get cut.

If it's a multi-building property near Hempstead Harbor Park or the marina, note whether all buildings should share one master or stay on separate systems. This is a locally dispatched job, so the tech who calls you back is working from Nassau County, not reading your address off a national lead list.
