Just got in my '09 Touring without the fob and pressed start. Got a big "NO KEY" warning on the multi-display. I'm guessing it would do the same for a bad antenna. But I'm just guessing. ;)

Well there's your problem. Anal key fobs don't work well.

Here's all of them

Thank you!

and today's consensus led to the car starting and working for them.

I just asked them to install a new clutch pedal sensor, just in case.

cost me $118.50.

That should fix it if my experience was the same as yours... see here:

Clutch pedal sensor solved my issue!

Too bad they raped you for $118 though... I fixed mine in 20 minutes with some sand paper basically. There is no magic in the switch, just sliding pole contacts on metal. The hardest part is removing the switch, after that it take minutes to clean and put back together. The new switch will probably do the same thing in the future too, keep that in mind!

$118 was totally worth being able to start my car the first time, every time. I certainly will, thanks for the information!
