My 2005 chevy cobalt factory radio says it is locked. how do i unlock it?
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 can't. I had to take it back to the dealer and they replaced the entire stereo... THEN it happened again and they seemed to have fixed it - but said it's most likely the car itself (the computer). Still have the problem randomly with the second new stereo from GM. Good luck with yours!
I have given up. I just figure I have to budget a trip to the dealer a couple times a year to "unlock" the radio.
I'll never buy GM vehicles again. The government is giving the US automakers a bailout for making troubled cars. Brilliant.
This happens to me often...right after I start the car and begin to drive. I have to turn off the ignition and restart the car for it to go away.
I asked the dealership to look at the problem, but they said there was nothing wrong.
