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 and an ignition switch, the lock device comprising:

• a locking unit including a lockbolt selectively engageable with the steering member to prevent its rotation, a carrier movable with the lockbolt, and a carrier pin supported by the carrier and movable from an extended position to a retracted position against a biasing member;
• a driver operable to rotate about an axis in response to rotation of a key cylinder via a matched key;
• and
• a post coupled to the driver for rotation therewith, the post being axially slidable relative to the driver in response to movement of the key within the key cylinder, the post having a first configuration holding the carrier pin in the retracted position against a force of the biasing member while allowing unobstructed movement of the carrier and the lockbolt relative to the steering member, the post having a second configuration overlapping the extended carrier pin in a radial direction perpendicular to the axis, thereby obstructing the lockbolt from engaging with the steering member, and the post having a third configuration which does not overlap the extended carrier pin,
• wherein the carrier pin is positioned on a side of the driver that is proximate the steering member, and
• wherein the driver is formed with detents engageable with a resilient member to positively define three separate operational positions of the lock device.
