ABSTRACT:
An electronic key system for a vehicle that prevents private information from being available to a third person. The electronic key system includes a terminal, electronic keys, and a device having comparing and control components. Each electronic key stores a distinct identification code and transmits the identification code to the vehicle. At least one of the identification codes is a restriction code for restricting the usage of the terminal. The comparing component is arranged in the vehicle and stores verification codes associated with the identification codes. The comparing component retrieves the identification code of one of the electronic keys and compares the retrieved identification code with an associated one of the verification codes. The control component restricts activation of the terminal when the retrieved identification code is the restriction code.
