Lock cylinder having a resetting block

Method for operation of a lock cylinder or a wheel lock a with at least one ignition starter switch at a vehicle with

• a cylinder core which is at least pivotably accepted in a cylinder housing wherein in the cylinder core at least one blocking element is intended which in a blocking position prevents a rotation of the cylinder core in the cylinder housing and in a releasing position releases a rotation in the cylinder housing and
• wherein a key channel extents through the cylinder core in which a key is insertable and with which the blocking element is movable between the blocking position and the releasing position and
• wherein by the cylinder core at least two rotation positions can be occupied, namely an off-position and a starting position wherein in the off-position a key is insertable and detractable in the key channel and in the starting-position at least one appliance, particularly a starter, of the vehicle can be switched on,
• characterized in that
• the following steps are intended for the operation of the lock cylinder
• a) a switching-on rotation of the cylinder core occurs by the appropriate key from the off-position via at least an ACC-position or a driving position into the starting position
• b) a simple backward rotation of the cylinder core by the key in the off-position is blocked by a resetting block, particularly in the previous ACC-position,
• c) a manual actuation of the resetting block, particularly by an actuation of an actuation element of the resetting block enables a released backward rotation of the cylinder core by the key in the off-position, particularly in the previous ACC-position.
