Ignition Switch: Description and Operation

The key in ignition switch is integral to the ignition switch, which is mounted on the left side of the steering column, opposite the ignition lock cylinder. It closes a path to ground for the instrument cluster chime warning circuitry when the ignition key is inserted in the ignition lock cylinder and the driver door jamb switch is closed (driver door is open). The key in ignition switch opens the ground path when the key is removed from the ignition lock cylinder.

The key in ignition switch cannot be repaired and, if faulty or damaged, the entire ignition switch must be replaced. Refer to Ignition Systems for the service procedures.
