With RF keys there is a reciever loop around the ignition barrel. This picks up the transmission code from the key and turns off the immobiliser
Aren't Transponder keys steel rods with a cluster on the end. The one I took for a swim certainly was. I don't think there is any ring around the ingition switch for my car , but of course the pattern of the key has to be right to get the ignition to start, which in the case of the AA key was only 95 per cent accurate - end tip being essential I would have thought.
