  - Smart Key PCM Learning
    
    Before learning procedure for FOB Key, Smart Key ECM should be registered PIN code first.
    
    In case of replacing Smart Key PCM, All of the keys should be newly registered again.
    
    In case that Smart Key PCM receives 3 times with wrong PIN, It is not allowed for neutralization and Key Teaching for 1 hour.
