Each lock operates with its own unique key, ensuring that no two locks share the same key.

Multiple locks are operated by the same key, allowing one key to open all locks in the set.

A master key opens multiple locks keyed differently, allowing supervisors to remove locks in emergencies.

To ensure exclusive control, master keys should be securely stored and accessible only to management.
