When I picked up my '07 M35 a couple of weeks ago, the dealer told me that when you "plug" the key fob into that little pocket to the right of the steering wheel, it charges the fob. Is this true? From looking at the fob, there doesn't seem to be any connectors or contacts for the fob to connect to this "mystery charger."

Thanks.

Unfortunately that isn't true. It only sends data to the vehicle when the battery is discharged, but does not actually charge the battery. Not the first time I've heard this before though. Someone's been informing the dealership sales people with some bad information..

Whoa! What else did this "dealer" tell you..?

Nope, not true but the dealer told me the same thing ... if the battery dies or its power is low you will know.. and its a simple change... I just replaced mine two weeks ago .. btw. the battery is CR2025

naw it doesnt, i remember the dealer argued with me when i said it didnt cause my friend has it and so i know , he said nope it does, he didnt change his mind until we went to service and i asked them the tech said no! he still said they should charge it somehow in there! ha ha ha

How about this: Your key fob end inserted into the skin under your chin charges your head into an antenna which amplifies the output of the fob signal for farther range for your fob.

As everyone else has already pointed out, that doesn't charge it. However, for the record, it could be charged without contacts as many batteries are these days. The problem with that is that even rechargable batteries eventually need replaced, so it makes more sense to use a watch battery in a fob.

Now this is true!

From the manual.....

NOTE:

The Intelligent Key port does not charge
the Intelligent Key battery. If you see the
low battery indicator, replace the battery
as soon as possible. See "Intelligent Key
battery replacement" in the "8. Maintenance
and do-it-yourself" section.
