Ignition lock steering column lock assembly

A lock device for a vehicle having a steering member for controlling the direction of travel of the vehicle, the lock device comprising:

• a steering member receiving aperture configured to receive the steering member and position the lock device in relation to the steering member;
• a locking unit including a lockbolt selectively extendable from the lock device for engagement with the steering member to prevent its rotation;
• a driver operable to rotate about an axis in response to rotation of a key cylinder;
• and
• a solenoid assembly operable to selectively prevent rotation of the driver, the solenoid assembly including a bobbin, coiled wire surrounding the bobbin, a core extending through the bobbin, and an armature movable toward the core when electric current is conducted through the coiled wire,
• wherein the armature has a shape generally defining a plane and includes an axial end face configured to selectively interfere with an abutment of the driver such that force on the armature from the abutment in response to attempted rotation of the driver is directed generally along the plane.
