I wonder if I can add a used key fob from another vehicle to my own vehicle. I have only one key and I wanted to buy a used one from eBay and add it to my keys. Is this possible? Another question: do I need to learn my already functional key while learning keys?
Thank you for watching, you can’t reprogram used keys and when you program a new key you have to reprogram the key you are using in the car too, I show you this in the video!
