Help!...07 Cobalt under 60k...electrical/door locks /anti-theft problems
I have started to have very annoying problems with my 07 cobalt. For no reason whatsoever the power locks will start to go crazy and lock themselves over and over again which cause the car to let out an audible beep(like if you hit the lock button on the keyless entry twice). It will do this randomly and for no reason...I will be in my house and all of a sudden I will hear my car beeping over and over again and I will go outside and see that it is locking over itself a million time and then it will stop for a minute and then start up again it is very random...the only way to stop the beeping is to turn the power on and if I want to go a 1/2 without running outside then I have to disconnect the battery...this is a very frustrating problem and I hope someone might be able to help

may also want to check the condition of the ground... I know on the 09's the battery is in the trunk, if yours is there also check the ground cables to/from battery and to/from the engine....

I'm sorry you are experiencing this issue with your vehicle. The other posters offer a good suggestion regarding the battery and/or ground issue.
Another possibility is an issue with the door lock switch; it may be sticking or need to be replaced. This is just a suggestion and is not meant as a diagnosis.
I recommend consulting with a certified technician for an official diagnosis. They will be able to assist you further after inspecting the vehicle.

just finished fixing this very same problem. Gm has a tsb for it. The door lock switches are corroding and sticking. Remove the switches and you will find green corrosion on the contacts. Clean or replace the switches.

I am having this same issue at the moment minus the beeping, and it continues while driving only stopping for a couple seconds before continually locking once again. I have an 05' and I'm just curious what some thoughts are on the passlock system shorting, or possibly something in the gear shift. I have a fairly new battery and the lock switches don't have any corrosion on them...any thoughts are greatly appreciated. This as been going on for about 4 hours now, but I'd like to fix the issue asap of course.
