Master Keying
There are several types of master key systems;
Simple Master Systems. Each lock has its
own individual key which will not operate any other lock in the system, but all locks in
the system can be operate by the master key.
Grand Master Systems. Each lock has its
own individual key as in the simple master key system and the locks are divided into two
or more groups, each group being operated by the Master Key, and all groups, or the entire
system, operated by the Grand Master Key.
Great Grand Master Systems (or
higher levels of keying). Each lock has its own individual key, and the locks are divided
into additional groups as needed including master keys and grand master keys with all
groups, or the entire system operated by the Great Grand Master-Key.
Most .51'' pin tumbler cylinders can be provided with
construction keying for use by architect or contractor personnel during building
construction. A special break-out key is used to permanently void the construction key.
This action eliminates further use of the construction or break-out key. Available
with all cylinder options. To order, suffix ''C'' to list number, i.e. 1801 CGMK.
