    • This key is not registered in the immobilizer unit Try to register keys by using "KEYS".
    • The communication was not good between the antenna and the immobilizer key by influence of metal such as key chains.
    • The communication was not good between the antenna and the immobilizer key by battery voltage low.
    A-2 Immobilizer system is not normal
    • Intermittent interruption between transponder and immobilizer unit.
    • The immobilizer key type is different It is not for this vehicle but for another one or for other company's one.
    • Key failure (transponder failure)
    • The communication was not good between the antenna and the immobilizer key by influence of metal such as key chains.
    • The communication was not good between the antenna and the immobilizer key by battery voltage low.
    A-3 Immobilizer system is not normal
    • The ignition switch was turned on with a non-immobilizer key.
    • The immobilizer key type is different. It is not for this vehicle but for another one or for other company's one.
