hello to all
when i bought my x5 a year 1/2 ago the remote on key wasn't working i got a brand new key and remote always work now today it won't work been it is less than a year 1/2 old the batt should go bad right.?? is there a fuse to check or relay as i think the part in the ignition is not charging the batt as it suppose to.??
any suggestions or things to check thanks
