One master key. Total control. No surprises.

What Is a Master Key System and How Does It Work?

A Master Key System allows multiple locks to be accessed by designated keys with different levels of access:

• Master Key – Unlocks all doors in the system.
• Sub-Master Key – Unlocks a specific group of doors.
• Individual Keys – Unlock only one specific door.

This system enhances security, organization, and convenience by reducing the number of keys needed and controlling access at various levels.
