Are you using the original key that came with the car? The chip in that key may have gone bad. Try using the spare key that should have come with the purchase of the car. You may also be having battery issues. If all else fails....call the people who really know how to rape you...DUM Dum dummmmm....the dealer

There are only 2 things you can try to fix this yourself: turn off the engine and open the driver side door (to turn the radio off). Wait 5 minutes, start your car.
If that does not solve it, turn off your engine, disconnect the car battery, wait about 5 minutes. Reconnect the battery (negative pole first - black connector) and try your radio again.

If neither one of these two fix your problem, I am afraid only a GM service center or dealership can fix the problem. The Cobalt is notorious for all kinds of electrical issues.

Thanks for using the fixya forums!

Start with the basics. Check the fuses (all of them) with a test light and be sure you have power to each and that they are good. Then be sure that the power lock relay is good by swapping it with another relay in the fuse block. If the fuses are good and the relay is swapped and the locks still aren't functioning, you may have an issue with the BCM. The BCM can be programmed to change the behavior, but if the car has had water damage, or other stress to the BCM (voltage, heat, etc.), it can sometimes damage the BCM and you will need to replace it and reprogram it at a GM dealership.

sounds like your steering column lock is binding you need to slightly turn the steering one way or the other while turning the key at the same time. this happens if the steering wheel is turned after removing the key. or when parked against a curb.
