I am stationed in Italy and have found that BMW service isn't good over here so need some help. My key fobs don't lock or unlock the doors anymore. I tried putting the key in the ignition switch and then removing it and pressing the lock button 3 times while holding the unlock button. In fact, I tried every combination of this with no luck. My key still reads at the dealer but won't link up with the vehicle. Is there something I can check or do I need to go to the stealer? Appreciate the help.
