Abstract

A process and device for controlling a motor vehicle central locking system that has multiple station operation from the driver's door and from the trunk lid. A central locking of the door locks of the motor vehicle is avoided when mechanically securing the lock of the trunk lid against opening from the outside without a key in the unlocked state. This is done by switch-controlled suppression of the effect of the locking control signal normally generated when locking.
