Programming Instructions:
You can’t program the 2005 Chevy Cobalt yourself – you will have to take the car to a Chevy Dealer or an automotive locksmith in order to have it programmed. I recommend trying an automotive locksmith first as they can be faster and less expensive.
NOTE: you will need to take the CAR and ALL THE REMOTES with you as the locksmith will have to hook up a computer right to your car and then reprogram all the remotes at once.
There is no onboard program for this, it requires special equipment at the dealers. What. A big waste of TIME,
Hi Nancy, you are correct, I did some more research and this car needs to be take to a dealer or an auto locksmith to be programmed. Unfortunately, some instructions are common between vehicles and others are not. I have updated the instructions accordingly. Thanks again and sorry it didn’t work out for you.
