Abstract: The invention relates to a device (1) for receiving signals for controlling a function in a vehicle, particularly for actuating the central locking of the vehicle, comprising an antenna (2), which receives the signals, and comprising an evaluation unit (5), which is connected down therefrom and which evaluates the received signals, and a control of the function ensues based on the evaluation of these signals. The invention provides that a matching unit (3) is connected between the antenna (2) and the evaluation unit (5) and matches the actual impedance of the antenna (2) to the input impedance of the evaluation unit (5).
