Your car has a OBD2 hook up under the dash somewhere on the drivers side, You have to have a computer to hook up to that ODB plug and reset it, If you live near a Autozone they will clear the code for you for free, One other thing you try is disconnecting your battery for about 30 mins, that works on alot cars to reset the check light.

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!

• A module which communicates on the class 2 serial data circuit which supplies VIN information to the radio is replaced and not properly setup with the correct VIN information for that vehicle. The only way to unlock the radio is by using a scan tool.
