Abstract
A motor vehicle ignition lock includes a housing, a lock barrel rotatable on the housing having a key slot, and a side bar on the lock barrel. The ignition lock further includes a solenoid on the housing and a slide on housing connected to a plunger of the solenoid. The slide has a notch which captures the side bar in an extended position of the side bar and an extended position of the slide. The ignition lock is unlocked in a mechanical unlocking mode by a key inserted in the key slot in the lock barrel to withdraw the side bar from the notch in the slide. The ignition lock is unlocked in an electronic unlocking mode by the solenoid when the plunger of the solenoid shifts the slide from its extended position to a retracted position to remove the notch from the side bar.
