Hold FOB under chin and open your mouth.... (you look stupid, but it does work)
Haha one of my fobs will unlock my car from basically as far away as I want to press the button and the other is about 5-7 feet. I've always been told to do the chin thing but I'm not going to.
QUICK, Someone make a kit and sell it for the entire e9x platform and make millions.Then yes, it would seem apparent that there is something wrong with it. Usually, range is a power issue, let us know how it goes considering I don't think those batteries are user replaceable. My x5 key(my only key) stopped working, so I have to manually twist the key in the cylinder. Sometimes the alarm goes off when I unlock it and I have to lock and unlock it a couple times for it to stop. So I might dive into a key project myself.
