An access system comprises a control unit in a vehicle, and a portable electronic device comprising a battery and a switch or a button. The portable electronic device comprises a transponder unit wirelessly supplied with power by the control unit. The control unit transmits a request signal to the portable electronic device. The portable electronic device checks, upon receipt of the request signal, whether supplying power by the battery is possible, provides wireless power supply by the control unit to the transponder unit, transmits a response signal to the control unit when supplying power by the battery is not possible, and when supplying power by the battery is possible and the switch or button was actuated within a specific time period around the receipt of the request signal. The vehicle is unlocked if the portable electronic device is recognized as belonging to the vehicle based on the response signal.
