  • PLUG FOR LOCK SYSTEM AND ASSOCIATED METHOD OF ASSEMBLY
    Publication number: 20260152971
    Abstract: The lock plug can have a plug body rotatably mountable within a lock housing for rotation around an axis, the plug body having a solid of revolution shape, the plug body having an insert component assembled to a primary component, a keyway defined in the plug body, the keyway having a length parallel to the rotation axis, the keyway adapted to receive a key blade matching a cross-sectional shape of the keyway, and a blocking mechanism protruding into the keyway, the blocking mechanism configured to prevent the plug from rotating unless actuated by the key blade and unless the key blade is of a matching type, the blocking mechanism integrated to the plug insert. The method of assembling the lock plug can include assembling components of the blocking mechanism to the insert component prior to assembling the insert component to the primary component.
