Abstract
During manual activation of an activation switch, authorization data are transmitted from a key to a lock. A steering lock unlocks the steering if the authorization data correspond to reference data. The ignition is then switched on and the steering lock is deenergzied as long as the ignition remains switched on. Consequently, the steering lock cannot be activated inadvertently during operation.
