Small business owners, commercial property owners, and even apartment building managers all share a common problem: there are many doors that require locks or access control and all key holders are not made equal. A building supervisor needs to be able to access all areas, an apartment renter just one. A cost-effective way of providing limited access to groups of people without high-tech alternatives for business security systems is the use of a master key system.
Any lock that can be opened with a key works in the same basic manner. There are a set of several pins of differing sizes that otherwise prevent the cylinder, or tumbler from rotating. When the key is inserted, it moves these pins to varying heights, creating a gap or shear line that enables the tumbler to rotate. However, one way to add more than one key is to use two pins instead of one. This allows for two different shear lines, or more simply, allows two keys cut in a slightly different fashion to open the same lock.How Master Key Lock Sets Work

As noted above, the primary use of a master key system is to restrict access to various locked areas so that only certain personnel can access them. There can be multiple levels of access possible, but the easiest way to explain it may be to imagine a hotel that offers regular rooms and luxury suites.
In that case, each traveler would receive a key that will only open the door to their room or suite. Cleaning personnel might only be assigned to the floors that offer the standard rooms and be able to access those floors or just one or two. Concierges or others that take care of suite users would only have access to those rooms. Any security staff would have access to all of those rooms, both luxury and regular, but perhaps not access to the back office, creating a sub-master key that enables them to open even more doors than the cleaning staff. Managers and building owners might then have the true master key that unlocks all of the doors in the building. Continue reading
