The invention relates to a transponder system (4) for a vehicle (2), comprising a transponder (6) that sends an access signal in response to an interrogation signal and a signal processing device (8, 40) to send the interrogation signal and receive the access signal that is sent by the transponder (6) in response to an interrogation signal. The system is characterized in that the signal processing device (8, 40) sends the interrogation signal as a transponder check signal when the vehicle (2) is deactivated. A warning signal is generated when the access signal is received in response to the transponder check signal. |
