The invention relates to an electromotive actuator with a housing for a central door locking system of a motor vehicle having a first slide adjustable by a first electric motor between two end positions. The first slide can be connected with a door lock of the motor vehicle independently of the end position and is preferably decoupled from the electric motor in the end positions, so that the first slide is manually adjustable between its end positions. Such an electromotive actuator is provided with a theft protection capability in the sense that, after a windshield of a motor vehicle is smashed in, an unlocking of the door by the inside locking handle is no more possible because the parts of the actuator are not actuated by operating the inside locking handle. Finally, an unlocking operation initiated from the outside is possible when the theft protection is put into operation. The theft protection capability is achieved by providing a second slide which can be coupled with the first slide by a latch adjustably guided at one of the two slides transversely to the moving direction of the slides and engaging the other slide under the effect of a spring element. The latch can be pulled back from engaging the other slide against the effect of the spring element from one coupling position into a theft protection position by a second electric motor and a control device so that the latch, together with the slide at which the latch is guided, can be moved away from the control device in the theft protection position.
