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!

does it happen at miscellaneous times, or is it at specific times, i.e., when you hit a certain speed, etc? If it's intermittent, then you may need to replace or clean the switch for the door locks. If it's at a certain speed, then most Chevrolet cars and trucks past about 1998 or so will have an automatic locking device that keeps kids from escaping while the car's in motion. They can be programmed to actuate at different times, so you may want to look at your owner's manual to see how to set yours, if you feel that it could be this.

Mine does this frequently, however it usually unlocks after turning off the car and starting it again. Sometimes I also have to keep messing with the dial, turning the radio on and off. If there is a cd, I keep trying to eject it. It varies. If there is an exact way, I don't know.
