I bought a 06 Cobalt off my mother-in-law, and she never used the locks, just used the key-less entery. now i got the car and one of the remotes has died a few times, and has been fixed, and the other can only unlock and not lock. All the locks in the car are completed seized up and the key can not even start to go in. i am looking for a replacement part online and having no luck, anyone know the part number?

 

Good morning,

I checked gmpartsdirect.com and there were locks available there when I checked. Might be worth checking out.

Hope this helps,

Decide the manufacturer brand you prefer then go to its official site and search for the door lock. You will also find the part number over there.
