Master key systems when implemented buy the wrong company can be extremely complex, confusing and frustrating. To give you an example we recently worked on a church in Cartersville, and I could kind of see the early signs of what I call the master key system haze. Unlike most she had already figure it out what employees were going to be given access to what areas at the church. This is extremely untypical by the way.
Master key system setup
Master key system setup is the most crucial part of a Master key system. You have to build in a lot of forethought, and anticipate growth. It’s pretty easy to simplify for most Master key systems. It comes down to who is allowed to go where. And then you have to remember but you can only really have so many sheer lines in one lock, and one shearline equals one key. If you add four Shearlines you have added for keys. it’s important to remember that every key that you add the less secure the lock becomes so I don’t typically like to go beyond 4 keys per lock. This is an example of a simplified Master key system.
Are Master key systems less secure?
In short, yes. The more complex you make a master key system the more shearlines you add. The more shearlines there are in a lock the more likely it is to be picked. How much less secure does it make your locks to have the master keyed? With a simple Master key system not very.
