I think I am having the same problem. I left the Volt for about a month and now it is locked. I called AAA and we put their charger on the 12 V battery in the trunk. Things started working again and we decided to leave it overnight on the two amp charge. I suspect things will look better in the morning. Not entirely sure why the 12 V ran down except that I was carrying the key fob around in my pocket and it was on from time to time. Probably operator error!
