How Master Key Systems Work
In a master key system, each lock is designed with a more complex pin mechanism than a standard lock. Typically, locks use a series of pins inside the cylinder that align with a specific key cut, allowing the key to rotate and unlock the door. In a master key system, additional pins, known as “master pins” or “spacers,” are added. These master pins allow for more than one key to operate the lock.
Common Uses
Residential Properties: Some homes with multiple entry points or rental properties use master key systems to give homeowners or property managers access to all doors, while individual tenants only have access to their specific units.
Commercial Buildings: In offices or businesses, master key systems allow management or security personnel to access all areas, while employees or staff only have access to specific rooms.
Hotels and Hospitality: A master key system allows housekeeping and management to access all rooms, while guests are given a key that only opens their specific room.
