A master key system is designed to enhance access control within a given environment by allowing one master key to operate multiple locks, while also enabling individual keys to unlock specific locks. This structure provides a hierarchical access level, where the master key serves as a universal key, granting entry to various areas with different access requirements. For instance, in a commercial building, a manager might have a master key that opens all office doors, while employees possess individual keys that only unlock their respective offices.

This system provides convenience and efficiency in managing access, as it reduces the number of keys that need to be issued and carried by authorized personnel. It is widely used in hotels, office buildings, and other facilities where different levels of access are necessary. The other options refer to different types of security systems, such as password-based or biometric systems, which do not share the same functionality as a master key system.
