Master Key System in Westbury, NY

A small strip of four or five storefronts on Post Avenue with a simple two-level hierarchy (master plus individual keys) sits at the low end of the range. A larger apartment building in New Cassel or a multi-tenant commercial block off Old Country Road, where you need a grand master, sub-masters for each floor or wing, and individual keys per unit, runs higher because of the added cylinders and key-cutting complexity.

We quote the exact price by phone after you tell us the door count and how many access tiers you want, before any technician is dispatched.

Commercial master key work means coordinating around tenants and building hours, not just showing up. Tell us whether the property is a Post Avenue storefront row, an apartment complex in New Cassel, or an office building near the Old Country Road retail corridor, since access points and whether we need a super or building manager present will differ.

We schedule around your building's operating hours and can work floor by floor in occupied properties so tenants aren't locked out mid-installation.

Before your callback, have a door count and a rough sketch of who needs access to what: which doors the super or building manager needs, which are tenant-only, and whether you want a grand master over multiple buildings or a single-property system. If you're replacing an existing master key system, note how many of the old keys are still in circulation so we know whether to rekey every cylinder or just add new levels to the existing hierarchy.
