No more listening to hardware store guys and Saturn salesmen. The generic keys runs the car just fine. The shop manual is not particularly clear, but I am certain Robert is correct. The keys don't include resistors or chips or whatever in the case of vehicles with Passlock II security. Seems like a half ass system to me. I guess it guarantees the lock cylinder must be turned to start the car, but it doesn't seem to be nearly as good as systems that depend on keys with RFID devices or even keys with unique resistor codes.
