Your Chrysler FOB ,has a chip that directly acts, with the antenna(black ring around ignition). It then tells the SKREEM, that the correct key with the right chip, is inserted and it's permitted to start the car. I'm surprised Viper was able to get their FOB , to interact with the CLP/SSM to lock/ unlock doors.
Send CL770 a PM, then maybe call him to talk directly to someone that , can help an better understand, one on one..
