What is the master key system
A master key system is where specific keys can open certain numbers of doors within an organization. It helps increase the convenience, as the management level people within the organization can hold low numbers of keys to open all the room doors quickly. Sometimes it can save lives when an emergency issue happens.
The security and stability of the master key system are essential. Mutual opening cases (one basic level user key can open lock cylinders with adjacent numbers) are not allowed to happen. Therefore a strict quality control before shipping is very critical.
