    Call your BMW parts department at the BMW dealer and ask them how much to remove and replace the remote battery.

    I have the same problem and I had someone check my key remote and was told the battery was still good but for some reason it will lock my doors but won't unlock them. May replace battery just to see what happens and you don't have to go to the dealership to get a replacement battery. Can be purchased at any store counter that sell watch batteries.
