An anti-theft device for a motor vehicle includes a key having a transponder. A lock has a keyhole for receiving the key. An antenna is in the vicinity of the lock. A control unit for controlling the antenna sends starting signals to the transponder and receives answer signals from the transponder. An assembly is turned on or off if the answer signals correspond to set-point signals. The antenna has a lighting device being controlled by the control unit for illuminating a region around the keyhole, at least before the key is inserted.
