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!

SOURCE: 2006 chevy cobalt - door won't open

Start with the basics. Check the fuses (all of them) with a test light and be sure you have power to each and that they are good. Then be sure that the power lock relay is good by swapping it with another relay in the fuse block. If the fuses are good and the relay is swapped and the locks still aren't functioning, you may have an issue with the BCM. The BCM can be programmed to change the behavior, but if the car has had water damage, or other stress to the BCM (voltage, heat, etc.), it can sometimes damage the BCM and you will need to replace it and reprogram it at a GM dealership.

Could be a problem in the shiftier. Your car doors lock automatically when you put the car in drive. They unlock when you put the car in park. The switch located in the shiftier can go bad causing the locks to randomly lock and unlock. Also, this can cause the key to get stuck in the ignition.

When i open the dr of my 2006 chevy cobalt the alarm goes off i have never used the clicker or has it ever done this before


On some models you set the theft system when you lock the doors and when you manually use the key to open the door the alarms will go off. To solve this use the key fob and see if you still have the problem. I don't think you will see the problem when you use the key fob to open the doors.

Chevy Cobalt TPMS issue


Most GM cars can be done by holding both lock and unlock buttons on the key fob. The horn will then sound and the you let the air out of the tire. The hot will sound once detected. Start at the left front and then the right front, right rear and left rear. The horn will sound again indicating the procedure has been completed.

Unlock a 2008 Chevy Silverado


This year model truck WILL allow the truck to be locked if the key fob is left inside, but not while fully engaged in the ignition. If you do not have Onstar service you will have to use a long piece of thin metal, possibly a straightened clothes hanger and work it into the upper part of the driver or passenger side door at the top rear corner. Be careful not to tear the door seal. If it's long enough to reach the power door lock button press it to open the door. If not then fashion a small hook on the end and hook the manual door lock release. There is just enough of a lip to hook on to. Hope this helps.

For about the last week or two, my car door locks just continually unlock, as if someone is pushing the unlock button on the key fob. It does this even when the keys are not it in, and while it's


Sounds like you have button to one of your door locks that is stuck, you remove door lock switches and disconnect 1 at a time to see which one it is. Over time a stuck switch will drain the battery it's sending voltage to all locks constantly, there's a switch tied to ignition switch on some models that locks door when you start the engine and unlocks doors when you shut the engine off, Chev. Suburbans have that
