 You can't unless you replace every module in the car, basically, and the key with something used. This is a sob story. Literally. But this goes for Audi, Mercedes, some of the Volkswagens. Some of the GM cars are that way, too, the Cadillacs and stuff. So if you've got one remote, get another one. Or if you've got one key, just get another key for your car. They're just not that much.
