Question about Chevrolet Cobalt

Low Beams Stay On

Low Beams on 2007 Chevy Cobalt remain on constantly even with key removed from ignition. I must disconnect battery when I get to work. There are fuses but no relays for high or low beams. It appears BCM controls the headlights. Anybody had this problem?

Also, the daytime driving lights are controlled by relay. It's possible the relay may have melted down inside and is shorted, remaining on even when primary ignition power is off. The relay runs about $15.00 to $20.00 USD and might be worth a shot to replace. Likely you can get one at a recycling yard for a dollar or two.

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

The key in my 2007 Chevy Cobalt broke off in the ignition. I need to replace the ignition but was told the key had a chip in it and the car would have to be reprogrammed to replace the ignition is this...


yes. I would use the dealer or a shop that knows your GM car and has the tools to do the job. A locksmith may be able to remove the key, that way you may not need to replace everything.

Keys stuck in ignition tires not locked it is in


Is the battery dead or disconnected? I've had that problem in another Chevy. With battery disconnected it would not return to the off position and allow me to remove the key.

Good luck!

Can't remove key


I have not had this issue on my Cobalt, but I did encounter it on my 1997 Chevy Blazer.

There is a shift lock interchange that doesn't allow the car to shift unless the brake pedal is pressed in, and won't allow the ignition to be turned fully off if the car is not in park.

To remove my key I used to shift from Park to Drive repeatedly attempting to get the switch to lock in place. While it was very annoying, it eventually worked and the key was able to come out.
