Expansion information is essential for accurately planning a key system. Expansion should include the
installed portion of the key system and planned future growth.
The key system expansion should be furnished in clear terms. For example, a three level system may be
described as follows:
Furnish a new grand master key system. Plan for a top control key. Provide for eight master keys
with up to forty changes each. Provide for twelve changes directly under the grand master.
Or,
1 Grand Master x 1 Control x 8 Masters x 40 Changes / Master plus 12 Grand Changes
Questions regarding the design and generation of key systems may be directed to Kaba Key Records
Department.
