Programming Instructions:
You can’t program this particular make/model/year 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.

Doesn’t work.

Hi Dave, I just double checked and you are correct, the instructions have been updated accordingly – unfortunately, you will have to take your vehicle to an auto locksmith or a dealer to have it programmed. Try the auto locksmith, it may be faster and less expensive.

This worked for me 2010 hhr. Key in and turn on but do not start. Hold down unlock button. And turn key on then off then on then off. Then release button. This will work to unlock only. You still have to lock manually from door.
