If you manage a building, office, or multi-unit property, you've probably dealt with the frustration of managing dozens of keys. A master key system solves this by creating a structured hierarchy of access.
How Master Key Systems Work
Every lock in a master key system is designed with two sets of working pins — one responding to the individual change key for that specific lock, and a second responding to the master key. The result is an access hierarchy:
- Change key — opens only one specific lock
- Sub-master key — opens all locks in a department or floor
- Master key — opens all locks in a building
- Grand master key — opens all locks across multiple buildings
Who Needs One?
- Office buildings with multiple tenants or departments
- Property management companies
- Schools, churches, and religious institutions
- Medical offices and hospital facilities
- Retail locations with stockrooms and staff areas
