"Master-Key" What does it mean?
We've all heard the term "master-key system", but it's often misunderstood.
Firstly, it doesn't mean that all your locks open with one key. That is simply "keyed alike" (KA).
Sometimes it refers to a specially-designed key/lock access structures that allows each key-holder access to their designated locks. But increasingly so, these access structures do not include an all-mighty "master key" that opens every lock. And the larger the locking system, the more the all-mightly "master key" becomes irrelevant. Does the CEO really need to carry around such a potential liability?
In small business the term becomes more correct. The owner/boss will carry a master-key to open everything; senior staff might carry another key that opens everything except the boss's office; whilst junior staff carry a key that only works the front door. In our ABC product, the 'A' key is a master key because it opens all your locks. The B & C keys only open some of your locks.
Another correct usage of "master-key" is in hotel / motel scenarios, where each room has different keys and the cleaners carry a master key that operates all rooms.
Matrix Key Systems can provide any of the above, with in-built contingency for lost and stolen keys.
