What Is a Master Key System?
A master key system lets different keys open different combinations of locks, while a single master key opens every lock. Essential for offices, apartment complexes, hotels, and any business with multiple access levels.
The Key Hierarchy
- Grand Master Key: Opens every lock — owners and building management only
- Master Key: Opens a department or floor — for managers
- Sub-Master Key: Opens a subset of locks — for team leads
- Change Key: Opens only one lock — standard employee key

Why Not DIY This
A master key system requires precise planning before any rekeying. An error in the hierarchy can let an employee’s key accidentally open a restricted area. A licensed locksmith designs the hierarchy on paper and validates it first.
