PIN-TYPE LOCK WITH AXIAL SPLIT CYLINDER AND/OR PLUG Abstract of the Disclosure: A pin-type lock cylinder telescopes a rotatable lock plug with a multiplicity of generally axially and radially aligned pin holes formed in each and pins in the pin holes controlled by a key inserted axially into the plug for properly radially positioning the pins and permitting unlocking rotation of the plug. At least one of the cylinder and plug, and preferably both, are axially split members formed of generally diametrically opposed parts with the axial split passing through the axially aligned pin holes. One of the split member parts having an axially and radially that surface extending continuously along said pin holes and forming one side of the pin holes with axial spacing therebetween, the other of the split member parts having axially spaced and radially extending grooves, preferably D-shaped cross section grooves, formed therein to complete the pin holes. The assembled cylinder pin hole grooves may face diametrically oppositely from the plug pin hole grooves, and the cylinder pin holes may be of slightly larger cross sectional dimension than the plug pin holes.
