you can't change it... you have to bring it to the dealer to get recharged.
The above is wrong.
One of two systems exist in current M3s. If the car has the Comfort Access option, the battery needs changing when it dies. In cars w/o CA, the "key" fob needs to be inserted into the ignition and trickle charges a different style battery. If if no longer holds a charge, change it out as well.
