    d) receiving, via a keypad at the vehicle, an additional code;

    e) passing said additional code to said comparator;

    f) comparing said additional code with said reference code;

    g) disabling said vehicle if agreement between said additional code and said reference code is not detected prior to said payment due deadline;
