If it's a stock un-upgraded 06 model, my guess is it's the wire came loose under, (inside) the ignition switch. And yes, it is a major pain to get to. I used a dremel tool with a cutoff wheel to cut the no tamper bolts, and after I re soldered the wire on the switch, I mounted it in an easy to get to location. Also I did my own version of a headlight bypass, with a relay.
