Programming Instructions:
You can’t program the 2003 Oldsmobile Alero yourself – you will have to take the car to an Oldsmobile 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.

Hi Donny, I did some checking after your note and unfortunately, you are correct, it turns out that with your make/model/year, you can’t program the remotes yourself and 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.
