Though an increasing number of companies and multi family buildings are upgrading to electronic access control systems, many facilities still rely on traditional keys. ![]() It is important that the design process is started early enough in the project to allow a reasonable time for consultation, manufacture, and installation.Interested In Learning More About A Master Key System? The key system will ultimately determine how the users interact within the building the process does therefore require a high level of participation from the building user group. The design process will result in the creation of a Master Key system for a building. These doors are usually only operable by the Differ Key and the Grand Master Key. These doors are usually issued with a key that operates that door alone (and no other) and the issuing of keys should be limited. Differ Keys should be limited to ‘Special Rooms’ for example, cash rooms and medical records. It is recommended that keys to operate one lock only should be kept to a minimum to allow sophisticated control keying as detailed above. This allows maintenance and cleaning activities to be carried out as easily as possible. Where an X intersects the Key and the door, the Key will operate.Īn exception to the rule is usually made for FM keys which often operate all FM type doors across the entire building. Using a lock chart you can plan which Keys should operate which mechanically controlled doors. For example, several different Tenant Companies occupying a building may have access under their Key to shared Entrance Doors, Kitchen & Meeting Room areas, whilst only being able to open their own Office Doors and not those of other companies under their Key.Įach door within the building is then assessed in relation to which of the Keys require access and the Master Keyed Cylinders are built to suit these requirements. There may be occasions where a number of user groups are allocated access to the same areas under their Key. The users could be organised into groups such as:-Įach of the user groups identified is allocated a Key. The first step is to consider the users that will use each department/building. The keys within the system are linked to groups of users who have identical access requirements rather than through their geographic location within the building. The benefits this can provide include: having an override when an Access Control pass is missing providing security in the event of a power failure and easily meeting fire escape requirements. Combining a Master Key System with an Electronic Access Control Systemĭepending on the requirements of the building, Access Control systems can be integrated with the Master Keying requirements incorporating Electric Strikes, Magnetic Locks and Card Readers. The Grand Master Key can therefore greatly impact the security of the suiting system and we, therefore, recommend that it is not provided with the system. In some systems, Grand Master Keys are often issued more than normal because they are either replacements for a lost key or are provided for convenience to users that need to access multiple areas of the building. This is a convenient feature for the Grand Master Keyholder that does, however, make the system vulnerable because the threat to the security of losing a Grand Master Key is so great. The Grand Master Key is the key in a traditional system that controls every door in the suite/building. ![]() Stocks of keys can also be held for immediate issues as there are typically fewer different key types for the entire system. ![]() Typically, only one key is required per person, and by eliminating unnecessary keys this reduces the initial cost of the system and the ongoing running costs. In a modern Master Keyed System, as it is possible for doors to be operated by more than one key, it is, therefore, possible to eliminate most if not all Differ Keys. A Differ Key is a key that can only open one door within a suite.A Sub Master Key is a key that can open a specific group of doors within the suite e.g.A Grand Master Key is a key that can open all locks in the suite/system.There are three main different types of keys, each type giving different levels of access. Master Keyed SystemĪ Master Keyed System is traditionally a system in which the locks can all be operated with different keys as well as one single key, called the Grand Master Key. Keyed Alike SystemĪ Keyed Alike System is a simple system that involves one key which can open all the locks in the system. Master Keyed suiting systems can be provided including any variations with Sub Master groups to any client requirements.
