Just recently purchased a 2005 chevy cobalt.Everytime I open the door the alarm system activates even if I used the key.The key fob I have is not working even after I changed the batteries. The car battery did go completey dead and I put a new one in. Does anyone no what wrongs.
everything looks connected. The power locks also wont work by button on door, but it locks and unlocks when you change gear park to drive. The battery was dead for a little while. Does anything need to be reset.
