A Grand Master Key System is designed to provide various levels of access within a building or facility, allowing for hierarchical control over different areas. In this system, there are typically three levels of keying:

1. **Individual Key Level**: This is the most basic level that allows access to a specific lock or group of locks. Each lock can have its own unique key that opens only that lock.

2. **Master Key Level**: This level allows access to a set of locks that are grouped together, enabling a single key to operate multiple locks.

3. **Grand Master Key Level**: This top level of the system allows access to all locks within the entire system. The Grand Master key can open all the areas that the individual and master keys can access, providing a broader level of control.

This hierarchy creates a structured access control system, making it easier to manage security for different areas while still granting flexibility and access as needed. Understanding this three-tiered keying approach is essential for anyone involved in locksmithing or security management within properties.
