Um yes but no the pcm I was using works in the magnum no problems without a matching vin being programmed in with a drb3 or a starscan as a matter of fact there was still a charger srt8 vin in the pcm I was using so there is no way the SKIM assumed it was a matching vin.
As long as the skim has been programmed to the key it will recognize the key and send a good/no good signal on the can bus. I have been through the FSM several times on this subject and there is no mention that the SKIM needs a vin programmed or a PIN assignment just that the rfid needs to be recognized by the module and it is very simply a go/no go switch signal.
