I want to help anyway I can. I really like the idea. One more thing to consider is our key gets recharged when inserted in the ignition. That is why there are no batteries. Or does it just have to be in the vicinity of the ignition to get recharged?
I know this from my first z4 that had no power in the extra key when I first bought it but after inserting key in ignition for awhile it was powered up to operate the door locks etc.
So it seems it must be a transmitter for the locks and a receiver for the immoblizer? I don't know if that makes any difference.
