The Immobilizer and Smart Key Reset is a feature that allows the registration of new keys when all master keys are lost. Once the system is reset, all previously registered keys will be erased and can never be reused  . Another feature, Add/Remove Key, is also available. Once a key is removed, it can never be reused. 

Follow the procedures in this bulletin to reset a vehicle Immobilizer or Smart Key system and to add and/or remove a key.
