Masion Keying DRASTICALLY reduces the level of security in the Masion keyed lock, for that reason if you have 3 or more people who need access to a door we STRONGLY recomend using an electronic lock like the E-Plex 5000 It is often combined with a master-keyed system in which the key is kept by the landlord. Each apartment (for example) has its own individual key which will not open the doors to any other apartments, but will open common entrance doors and communal service areas. ![]() This system is widely used in apartments, office blocks and hotels. We can even set up padlocks to your master-key system. To visualize this, it can be thought of as a hierarchical chart, or a tree. Larger organizations, with more complex systems, may have several levels of master keys, where the top level key works in all of the locks in the system. For example, a standard 6 pin cylinder, which was designed to be operated by only one key, can be operated by up to 2^6=64 keys if there are two shear points in each chamber. The fact that some pin chambers have two shear points allows for more options when picking and it also allows for more keys to operate. ![]() For example, master keyed pin tumbler locks often have two shear points at each pin position, one for the change key and one for the master key. Some people think master keyed locks are more secure than single keyed locks, but that is not the case, in reality master-keying makes the locks less secure. Usually, there is nothing real special about the key itself, The pins inside the locks are configured in a way to operate with two, or more, different keys: one specific to each lock (generally refered to as the change key), which cannot operate any of the others in the system, and the master key, which operates all the locks in the set. It is ideally suited to residential and commercial applications such as front and back doors.Ī master key can operate from 2 to well over 2000 locks. This system allows for a number of cylinders to be operated by the same key. With an individually keyed system, each cylinder can be opened by its unique key. We can help! We understand not only the how and why, but the why not when it comes to master-keying. Individually keyed system
