Comfort Access*
If the car is equipped with Comfort Access, only
insert the remote control into the ignition lock
under special circumstances, refer to page 33.

but on page 33 I doesn't seem to say why not. Below loops back to above

Starting the engine
You can start the engine or switch on the igni-
tion when a remote control is inside the vehicle.
It is not necessary to insert a remote control into
the ignition lock, refer to page 55.

The only time I do is when I go through the car wash.

You bring your M3 to a car wash?

My battery finally started giving up after 3 years of ownership, 14K miles, driven almost daily. For some reason I didn't think to search the forums or even RTFM, I just assumed it was some proprietary battery that my dealer would have to replace under warranty, especially since it lasted 3 full years. I felt pretty foolish when all my SA did was pop off the cover and slide a fresh CR2032 in. Probably cost me more in gas to drive over there than the battery would have by itself.

So have no fear, just replace it yourself! Cheers.
