Immobilizer Generation 4 (Adaptation)
Key Matching (New)
Key Matching (Used)
Keys are locked during their initial/first learning process and cannot be learned/matched to a different immobilizer system via factory procedures. Therefor, existing keys from a specific vehicle and immobilizer identity can be re-learned/matched to that same vehicle/identity at any time, while used keys from different vehicles or old identities cannot be learned/matched!
