Thanks guys problem solved. It appears that the installers had inadvertently left the spare key behind the console when they fitted the unit. So it appears that everything was working correctly.

Thanks again.

I've just had an idroid 8000 2din GPS unit put in my 2010 Kizashi. My problem is that now I can not lock the doors using the door button. I can lock it using the key FOB and I can unlock using either. Any suggestions?
