Designed to allow differing levels of access to a range of people, Master Key systems have been popular in larger business, schools and organisations.
A master key system is a key plan that allows selected keys to open a number of pre-defined doors. It gives different people access to certain doors or locks, and can control who has access to these.
In most cases a manager my have the Grand Master that allows them into every lock, while a junior employee might only have access to the office where they work. A carefully mapped out plan is created that defines the levels of access and ultimately determines how the key system is developed to provide the appropriate access levels.
Add a restricted key protocol and you have the added advantage of managing any copying of keys, greatly reducing risks associated with lost or mislaid keys.
The modern version of the master key system is the smart lock system, or access control which all utilise levels of electronics to control the access. The added advantage of tracking access and the reduction in costs around key cutting and changing locks will see these systems soon replace the traditional Master Key systems.
