A well-designed master key system means a property manager carries one key that opens every door, department heads carry a sub-master that opens their floor or wing, and individual employees carry a change key that only opens their own office or storage room — all without anyone needing a key ring the size of a fist. Designing this correctly takes planning before any cutting happens, because a poorly designed system either over-restricts staff or, worse, accidentally lets a change key open doors it shouldn't.
We map your building's access hierarchy first — who needs access to what, and at which levels — before specifying cylinders and cutting keys. This matters most for multi-tenant buildings, schools, medical offices, and any property where staff turnover means keys need to be reissued or restricted without re-keying the entire building from scratch.

We document every door and who actually needs access to it, building the hierarchy before specifying hardware.
Grand master, sub-masters, and change keys are planned to match your real organizational structure.
Compatible cylinders are installed or retrofitted across all doors in the system.
Keys are cut and issued with a key-control log so you know exactly who holds what.
Master key systems are priced by design complexity and door count — we provide a full proposal before any cutting begins.
