1. A safety system for a locking device of a motor vehicle comprising:
a unit control device comprising at least one power switch for actuating an electromechanical unit into a blocking state;
a central control device comprising signal links to the unit control device and further unit control devices of the motor vehicle, the electromechanical unit being controllable through the central control device via the signal links; and
an electrical lead connection being independent of the signal links;
wherein the unit control device is connected to the central control device through the independent electrical lead connection, and wherein the power switch of the unit control device is controllable by the central control device via the independent electrical lead connection, the central control device thus enabling, via the independent electrical lead connection, the unit control device to actuate the electromechanical unit into the blocking state, the actuating not being possible without the enabling by the central control device.
