Within large public or commercial structures, managing access control in a flexible and hierarchical manner is a primary requirement. Only those who are authorized will be able to access certain areas. In the residential sector, having a single key that can open various entrances such as doors, gates and garages is synonymous with practicality.

 

CISA master key systems are therefore the most convenient and economical solution for managing accesses, while guaranteeing maximum security and protection of the building.

 

Furthermore, the possibility of designing the system with a patented key avoids unauthorized duplication.

To obtain a copy, you must identify yourself as an owner by presenting the Security Card.
