Master Key Systems

What is Master Key Systems?

Master keys are something that many people seem to be fascinated with. The fascination, I believe, is due to the confusing nature of the device. How is one key, opening two doors, but another key that is opening one of those doors is not opening the other? Is it the key that is special? Is it the internal mechanics of the lock? Well, I must warn you that there is some math involved in these answers. Now before you stop reading (I may have lost some people already) it is nothing too difficult. At the lowest level of comprehension it is addition and subtraction, and at the highest level of understanding (at least what is expressed here) it is exponents. It is nothing scary. After reading this piece, you should be able to understand any master key system, varying from the simplest version to the most complex. With the basic understanding, one should be able to extrapolate potential additions to the system’s security.
