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.
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.
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.
With a master key system, you
can configure keys and cylinders so the same key opens several doors, thanks to multiple
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.
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.
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.
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.
Within large organizations, it is essential to have clear and well-defined structures for access control. At the highest level of the system, the head of departments and managers can have unrestricted access to large areas of the building. 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.
There are three levels in a typical GMK::
This allows a capillary assignment of accesses based on the needs of individual users who frequent the building
The MK (Master Key) and GMK (General Master Key) solutions allow to organize the flow of guests and staff in a secure way to facilitate the service and ensure the privacy and security of guests.
The application of master key systems in a hotel context is perhaps the best known even by those who are not familiar with these solutions: we all know that, generally for cleaning and maintenance of the rooms, the management has passepartout keys. These actually are the Master Keys.
