Yes Neo. That is correct. He has to have an already programmed Master Key in order to add additional keys. Once you get down to the valet key you can no longer add in additional keys using a diagnostic tool or through On Board Programming, (OBP)

Crap, I got my hope up on that one... Thanks for all of the info guys. Now I need to see if it's better to have my dealer take care of me or to yank out my ECM (no idea how to do it) and go without my car for nearly a week...
