Hi mab01uk !
without your help for the control unit I would have to go to BMW...
Thank you very much
I've tried this method:
"1. Have all the keys on you when you get into the car.
2. Get in and shut the doors (dont open them untill your finished programing)
3. Put a key in the ignition and turn to the first click, then back and take the key out all within 5 seconds
4. Now hold down the unlock button, while holding it down press the lock button 3 times, then release the unlock button, the doors should lock and unlock. DONT touch the doors or door locks yet.
5. Repeat action 4 for any other keys"
But it didn't work, just that I've only got one key with remote control so I only did it once.
Tomorrow i'll try the "secret code"
