Hey! 1st time poster on this forum. Not much experience. Owned a 2002 Z3 and now have a 2006 750LI. They have really been my wife's cars. That being said, I was wondering if someone had figured out a way to charge up the key fob without having to drive the car for several hours? Seeing as my key rarely gets used, has someone built a mockup charger for doing ths?
