Abstract
A key assembly for operating a coded security system is structured with a plurality of information carrier members mounted on a longitudinal member of the key assembly and angularly arranged thereon to define a code for a security system operated by the key. Alteration of the code is effected by changing the relative orientation of the information carrier members by threadedly loosening the longitudinal member upon which the carrier members are held, readjusting the position of the carrier members and tightening the longitudinal member to hold the information carrier members fixed in a desired relative position defining the code.
