Which master key system types are there?


A master key system for organisations illustrates the functional organisational chart of a company. With its very high-performance locking systems, EVVA can even replicate extremely complex organisational structures. The objective of a master key system is to boost the convenience and security and cut the administrative efforts.


The special characteristic of a master key system for residential complexes is that all residents have access to the main entrance, basement, letter box as well their own property using only a single key. This boosts convenience and simplifies management. Individual locks for service engineers can also be integrated.
