Question about 2007 Chevrolet Cobalt Coupe
My 07 chevy cobalt radio quit working for about 1 week. Nothing would be read on display or power button would not work. We checked all fuses and everything. Now the radio say 'No Vin'. Is this the same thing as LOCKED? Will I have to take to Chevy dealership or can a mechanic do it with the right tools?
Dealership has to reset radio code.some times owners manual will help.

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!

you will need to do a security relearn.
1.turn key to on position and leave on
2.after 10 minutes the light will flash and go out turn the key on to off 3x then leave on again.
3. do this 3 times for 30 minutes then after 30 minutes your 3rd time and after turning the key 3 times the 4th time start the car. it should start right up.

if you hold the 1 and 4 presets and you get 3 lines like this - - - then that meens there is no code stored so the problem is not in your theftlock but the radio or power to it.
