. . . . the same thing happened to me last night! :yikes:
Was out riding. Stopped at the store on the way home to pick up some milk.
When I came out of the store, popped the frunk, put the milk in and then turned the key to start up and . . . . . NOTHING. No lights, no clicks, no nothing.
Turned the key again and . . . . .NOTHING. The worse thing about this was that your avatar popped into my head - very scary.
After a couple more times - suddenly it turned on.
What had happened ( I am pretty sure ) is that the ignition was stuck in the "down" or "in" position - where you push it in or down to open the frunk or seat to gas up. I don't know if some dust/dirt/grime had gotten in there, but whatever pushes the key slot back up was jammed somehow and the ignition would not return to the engine turn-on/off mode.
So, if it is not an electrical problem (which you have seemed to verified) check the mechanical operation of the ignition switch. Maybe you picked up some dirt on the trip to AZ that is now interfering with it.
You might also try using your spare key - maybe your regular key electronics got fried during the trip down - the problem may be with the key. (just another shot in the dark guess)
