ABSTRACT:
An automotive vehicle has a body provided with a passenger compartment and a luggage compartment. Doors, which close the passenger compartment, carry latches which engage the body to secure those doors. While the doors have exterior handles which are connected to the latches to release the latches, at least when the latches are set to an unlocked condition, each latch may be shifted to a locked condition in which the exterior handle for its door will not release it. Each door also carries an electrical actuator which is coupled to the latch of the door to shift that latch between its locked and unlocked conditions. Two of the doors carry switches which are accessible from the passenger compartment and when operated will cause electrical actuator to shift the latches in unison to their locked or unlocked conditions, depending on the manner in which the switch is manipulated. In addition, the luggage compartment contains a remote switch which is connected to all of the actuators and when operated causes the actuators to shift all latches to their unlocked condition.
