Well, it happened again today. Same scenario. Except this time it still wouldn't start after lock/unlock try # 1. She tried two more times and called me. I told her to wait a few minutes and try again. She did and it started.

No CEL. I asked her to get the codes read at Autozone after the first episode. She never did.

So now she is on her way directly to our favorite indy mechanic.

Update: Phone rang while I was typing. Mechanic says 90% sure it's crank position sensor. $226.87. I told him to go for it.
