How does a hierarchical system work in a master key setup?

In a hierarchical master key system, keys are organized in levels of access. The top level may have a grand master key that opens all locks in the system, while lower levels (like sub-master keys) have access to specific areas. This structure allows for efficient and secure access control, ensuring that each key holder only accesses areas relevant to their role.

What is the importance of having a proper key plan in a master key system?

A proper key plan is essential in a master key system as it outlines the access each key has within the system. It helps in managing key distribution, ensuring that the right person holds the right key. This plan is crucial for maintaining a high level of security and for the efficient operation of the management systems, as it prevents unauthorized access and ensures that keys work with different types of locks as intended.
