Abstract: An ignition lock for a motor vehicle includes a carrier element for holding an ignition key that is inserted in the ignition lock. The carrier element is movable along a longitudinal axis of the ignition lock. The carrier element pushes a slide bar from a blocking position to an unblocking position when the carrier element moves along the longitudinal axis. A latch bar, when in its latching position, restricts a movement of the carrier element along the longitudinal axis and, when in its unlatching position, allows the carrier element to move along the longitudinal axis. When the latch bar is in its unlatching position and the slide bar is in its blocking position, the slide bar prevents the latch bar from moving from the unlatching position to the latching position.
