Master Key System in South Hempstead, NY

A master key system isn't one flat fee. It's priced on the number of doors involved and how many tiers the hierarchy needs: a simple building master over a handful of tenant units costs less than a multi-level system where a grand master opens everything, sub-masters open a floor or wing, and individual change keys open single units.

When you call, have your door count and a rough sense of who needs access to what (owner, super, individual tenants, maintenance) ready. That's what the technician uses to quote a real number on the callback, not a guess based on square footage.

South Hempstead sits along Peninsula Boulevard near the Southern State Parkway, in a compact grid with no LIRR station of its own, so a technician driving in works off street address and building entrance, not a station landmark. Dispatch passes your job to the nearest available locksmith, who calls you back within a few minutes to talk through your building's setup and quote the job before anything is scheduled.

Have the building's main entrance and any gate or buzzer code ready so the tech isn't stuck at the curb once they arrive.

Master key jobs move faster when the technician isn't starting from zero. Before your callback, jot down the number of doors that need to be on the system, whether any locks are already keyed alike, and who the different access tiers are for (management, staff, individual units).

If there's an existing master key or a locksmith's prior key code on file, mention it. That single detail can change whether the job is a re-key against existing hardware or a full new hierarchy built from scratch, and it affects the quote you get on the callback.
