Hello, I bought a 9000 CS Bj. 97. Unfortunately there is only one radio remote control (radio) and it is defective. In the meantime I was able to get 2 relatively new remote controls at ebay. My problem is now the reprogramming of these remote controls on the control unit in the car. Depends on whether the car starts at all, because with the remote control also the electronic immobilizer is activated or deactivated. Has someone experience with it and can give me a relevant Thank you.
