2003 Oldsmobile Alero Remote Programming
Programming Instructions
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.
💡 Tip: If it doesn't work, try again — timing can be tricky!
