I tried searching but couldn't find the exact information I was looking for. I'm helping my friend convert his 99 GSR from OBD2 to OBD1 by swapping in a 95 GSR ECU but one question he asked me about the swap which I was not able to answer was, if whether or not his chip in his key will still be functional? I'm pretty sure the information for a chipped key is in the ECU therefore by swapping the ECU's wouldn't that override the whole chipped key anti theft?
