Abstract

A method and device for the electrical control of a central locking system and of a mechanical securing device (that provides additional lock protection) for motor vehicles by a lock cylinder that interacts with at least two control switches. This method and device ensures a better utilization of the electrical control switches, in that, an unlocking control switch assigned to the unlocking of the central locking system and the deactivation of the mechanical securing device is switched in addition to a locking control switch assigned to the locking of the central locking system. If the lock cylinder is pivoted in the locking direction beyond its regular locking position, the resultant joint switching state of the two switching control devices is evaluated to activate the mechanical securing device.
