The carrier pin is positioned on a steering column side of the driver. The operational positions of the lock are provided by detents formed on the driver. ## Claims ### Claim 1 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. ### Claim 2 (depends on 1) The lock of claim 1, further comprising an ignition switch operable by the driver between an off position, an accessory position, and a run position, wherein the off, accessory, and run positions are defined solely by the detents of the driver. ### Claim 3 (depends on 2) The lock of claim 2, wherein the detents of the driver are formed at an outer peripheral portion of the driver remote from an ignition switch engaging portion. ### Claim 4 (depends on 1) The lock of claim 1, further comprising a housing at least partially receiving the driver and the locking unit, and a cover secured to the housing and at least partially receiving the steering member and defining a steering axis thereof, the lockbolt being movable through the cover to selectively engage the steering member. ### Claim 5 (depends on 4) The lock of claim 4, wherein the carrier pin is positioned between the driver and the cover. ### Claim 6 (depends on 4) The lock of claim 4, further comprising a solenoid assembly positioned within the housing and operable to selectively prevent rotation of the driver. ### Claim 7 (depends on 6) The lock of claim 6, wherein the solenoid assembly includes 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, and wherein each of the bobbin, the coiled wire, the core, and the armature are held directly by the housing in a common interior space with the driver, without a separate solenoid casing or housing. ### Claim 8 (depends on 7) The lock of claim 7, wherein the housing includes a pair of guides slidably receiving and retaining corresponding projections of the core. ### Claim 9 (depends on 8) The lock of claim 8, wherein the housing includes a pair of recesses receiving corresponding projections of the armature to define a pivot axis of the armature. ### Claim 10 (depends on 7) The lock of claim 7, 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.
