Who Keeps The Grand Master Key? [Solved]

The Department Heads and Supervisors would have the highest level of access, a master key that could open any lock in their respective buildings. For example, Master Key 1 would be able to unlock all the doors in Building 1, while Master Key 2 could open all the locks in Building 2 and so on.
