Master key systems are a convenient solution for managing access to multiple doors within a building. They provide a hierarchy of keys that allow designated individuals to access specific areas while restricting access to others. These systems are particularly useful for commercial and institutional settings, where multiple individuals require access to different areas. With a master key system, building managers can easily control who has access to which doors, and reduce the need for multiple keys. This can improve security, simplify key management, and provide a more efficient and effective way to manage access to buildings.
