Abstract
A method of keyless locking of a motor vehicle is described. A transponder exchanges a code with a transceiver. A control unit compares this code with the expected code and, if a match is found, activates a closing system of the vehicle in the sense of locking it. This control unit activates at least one display means. A locking command is generated on actuation of at least one operating element. In a first step, a search signal is delivered by the transceiver when the operating element is actuated in order to determine the position of the transponder on the basis of the response signal sent back by the transponder. In a second step, the display means is activated when the transponder is in the interior of the vehicle and/or on the side of the vehicle opposite the actuated operating element. In a third step, the closing system is activated in the sense of locking it if the operating element has been actuated again.
