The mobile device performs a second communication with a key module when the key module is overlapped on the mobile device. The mobile device performs a first communication with the authentication unit. The mobile device transmits a challenge code, which is transmitted from the authentication unit, to the key module via the second communication. Upon receiving the challenge code from the mobile device, the key module generates a response code using the vehicle key code stored in a local storage, transmits the generated response code to the mobile device. The authentication unit performs user authentication using the response code.
