WHAT IS A SUBMASTER KEY?

A submaster key is a type of key system used in lock management that allows for more controlled access within a larger system. It can open multiple locks, typically within a specific area or department, while still being subordinate to a master key that opens all locks in the system. Submaster keys enhance security by limiting access to certain areas while providing flexibility in key management. They are commonly used in organizational settings, such as hotels or offices, to balance security and convenience.
