Hi
I'm renting a chevrolet cobalt. Last night, I accidentially left the keys in the ignition. After getting my car opened and retrieving my keys, I was unable to turn the car over. Assuming that I had let the battery run down, I got a friend to come over and jump the car. This did nothing. In the warning display panel in the car's dashboard, a icon keeps popping up that shows a car with a lock. I believe this relates to the cars automatic battery saver. I am at a loss. I do not know how to turn the battery saver off and restart this car. Since the car is due in to the rental place today, I would like to figure out this problem as soon as possible. (oh yeah, I called the rental place and they don't know what to do either) thank you for your help

Call a local Chevrolet dealer--they should be able to solve the problem immediately.
