Vehcile stereo codes are different for every radio to deter theft. The codes are usually around 4 numbers. There are a couple ways to find out what your code is. First, check your owners manual, someone at some point may have written it down in there. Also, there may be a card somewhere in you paperwork that has the code. If you don't find the code, the easiest way to find out what it is, go to you local GM dealerships service department, if you give them you VIN number they will be able to give you the code (most of the time free of charge). My last suggestion, pull the radio out, sometimes it will be written on the unit.

SOURCE: my 2005 chevy cobalt factory radio is locked

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!

My radio is lock how can i un lock it


Go to your local GM dealership. They have to retrieve a radio code with the factory scan-tool. They will then have to call tech-support and give them the radio code, so that they can get your unlock code.

It would be a good idea to have them write it down for you, and maybe even keep it on your owners manual in case this happens again. They will probably charge you 1hr labor for this which will be somewhere between $80 and $120.

How to unlock radio


The unlock code for your radio is specific to your radio in your car, the code should be in your Owner's Manual Packet, if not you will need to go to the Chevrolet Dealer to get the code.

The radio in a 2005 chevy cobalt in lock need it unlock


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.

I have a 2006 cobalt all fuses are good new battery no codes show up when the ignition is turned over lights blink motor doesent turn over there is a light on the dash that has a car with a lock through it


This sounds like the anti-theft system - Are you using the original factory key? Have you tried locking the car with your remote and then unlocking it with the remote (if you have one)?
