How does it work?

The best way to describe the master key system would be to imagine dividing areas of a property into different sections with different security clearance levels. All occupants of the property will have access to key entrance doors whilst other occupants can can have the same access, with additional restricted areas. The owner of the business will be able to access every door within the property. Good preparation and planning at the initial stages of the project is essential to ensure that they system performs well when it is implemented.
