Remote Battery?
The cars great, no regrets at all, but one thing bugs/puzzles me. The key seems to activate by proximity.
How does the key battery charge? Is there a key hole im not aware of? Thanks |

I believe holding the back of the fob to the key icon on the steering column charges the battery, and the car will alert you to do this if necessary.

I know on the e90, there was a key fob slot that would charge it, however, I was not aware of one on the f30, that would be news to me but excellent if true. |

I don't see anywhere on the page you posted where it discusses charging. New key uses a Lithium coin cell, you simply replace it when depleted. If the remote battery is depleted, you hold the key next to designated location on steering column and it will wake the key electronics (even with a dead battery) enough to allow you to start the car. Does not charge the key, but allows the car to validate you have the correct key (even with a dead battery).
As far as the proximity is concerned, the electronics in the key sleep until they are woken by a special signal coming from your car. This is how they can preserve the battery to last for a couple years+. Last edited by claykin; 12-06-2012 at 08:05 AM.. |

try with both keys (spare and original), try changing the battery and see if that helps, if not the dealer would probably be able to help |
