MAXIMUM CONVENIENCE



The great advantage of master key systems is that they are practical, especially in buildings with several entrances, as they grant access to all communal areas and your own private space with a single key.

All keys have the same combinationof elements in the first part to access communal areas. The final part has a unique, personalised combination for private access.

LOTS OF KEYS?

TOO MANY PROBLEMS
 

Keys are incredible things, they open up possibilities while keeping us safe at the same time.
However, when you have too many keys in a bunch, they can become a problem, especially when they are lost or stolen or you have lots of different keys and their copies to handle.
 
 

 

THE SOLUTION?

CISA MASTER KEY SYSTEMS

Fewer keys, greater convenience and security.
CISA master key systems are the most convenient and value-for-money solution to control all accesses. They ensure maximum security and protection of buildings and grant access only to those with authorisation.
 
 

 

HOW DO THEY WORK?

ONE KEY - MULTIPLE ACCESS POINTS

With a master key system, you can configure keys and cylinders so the same key opens several doors, thanks to multiple personalised combinations.
It offers many benefits and applications
for single-family houses, apartment buildings with several communal entrances or public and private facilities that need a hierarchical system to control access.

and the relationship created between the two, depending on the needs, setting and size of the building.
 

 

 

DOUBLE THE SECURITY



Not only are master key systems practical, they are also secure because both the key and the cylinder protect against unauthorised duplication and forced entry.

They also mean lower costs for duplicating keys and replacing cylinders.

SYSTEM SECURITY

 
 

There are 39,000 to 85 million different cylinder combinations per master key, in other words, the probability of producing an exact copy of the key in the chosen system is non-existent.

PROTECTED KEY DUPLICATION

 
 

CISA guarantees safe key duplication thanks to its patented solutions. Keys for CISA patented systems can only be duplicated at the 240 CISA Solution Partners or 700 CISA authorised centres.
The Security Card supplied with the system contains a personalised code so only the holder can request a duplicate key.

ATTACK RESISTANCE

 
 

  • Certified protection against pulling and tearing, (patented SNAP RESISTANT technology).
  • Certified protection against bumping (patented BKP - Bump Key Power - technology).
  • High resistance to picking, (patented system with new floating drivers).
  • Certified protection against drilling, (bitting system in hardened steel).
  • High resistance to forced entry using the wax impression technique (special configuration of the springs).
 

A SIMPLE SYSTEM FOR COMPLEX APPLICATIONS



Master key systems are essential in complex facilities where, as the number of people, locks and rooms increases, it becomes necessary to control access using keys with different levels of authorisation.

Master key systems reduce the number of keys in circulation and make organisation and control a lot easier.

A SYSTEM WITH BENEFITS FOR ALL APPLICATIONS



Master key systems can be configured to meet the different needs of residential or non-residential buildings.

It is ideal for private homes and large apartment buildings because it is both practical and secure and means no more heavy bunches of keys. A single key, with a personalised combination, opens both private and communal accesses.

It is an advantage for non-residential buildings because there are fewer keys to manage and hierarchy and control of accesses throughout the building is easier.

At the intermediate level, executives and small teams will be enabled to access only certain areas. Finally, employees who only need access to their office or work area.

HIERARCHICAL CONFIGURATION OF ACCESSES

There are three levels in a typical GMK:: 

  • Level 1 - Master Key (GMK) unlocks all cylinders at all sites.
  • Level 2 - Master Key (MK) will unlock all cylinders within a specific building on the site.
  • Level 3 - The sub-master key (SMK) unlocks specific departments or areas within one of the buildings.

This allows a capillary assignment of accesses based on the needs of individual users who frequent the building
