Master key systems for all needs:
- Large public or commercial premises : flexible, hierarchical access management.
- Residential: one key opens all doors.
With CISA master key systems, one key opens all accesses (doors, gates, garages…). Entrances can also be managed according to a hierarchy: only authorised people have access to certain areas. Master key systems with patented keys prevent the risk of unauthorised duplications: copies can only be obtained upon presentation of the Security Card.
