Master key systems offer a level of security tailor-made to your requirements.
Security and convenience of movement are inevitably in conflict with each other. However, with a little thought and planning a master key system can be designed to suit the client's precise operational requirements within each building. With security tailored to the needs of the people who will use it, the system allows keyholders to move freely, but only through areas they need to enter.
Effective security requires effective control and management of keys.
In an ASSA master key system, each person can be issued with their own key that only opens those doors appropriate to their job function.
Effective management of a key system is essential if it is not to lose its security over time.
