Car shut down while in toll booth. would not recognize key everything went black on dash. could not get out of car due to toll barriers. then about 30 sec later message came on dash that needed to move key fob closer - i do not remember exact wording. i took key out of my right front pocket and wave it over start button. was able to then start car. while driving home passenger air bag warning sensor came on and remained on the remainder of the time until i got home (about 40 minute drive. there was an adult in the passenger seat.
