摘要
A method for preventing disarming of an immobilizer system is provided to enhance authentication efficiency through additional time insurance till normal operation even if the immobilizer system is replaced. An immobilizer system is disarmed under a variety of external conditions. The immobilizer system induces the replacement of parts having ciphers after recognizing abnormal vehicle access. Authorization is rejected with respect to replaced parts when the authentication is requested from an EMS to a BCM with respect to the replaced parts. An RKE LOCK signal input is induced through the rejected authentication procedure. A central door lock is performed if the RKE LOCK signal is input. The immobilizer system is normally authorized if predetermined time elapses in an ARM state, and the RKE LOCK signal input is induced.
