2005 bmw 645ci (E63) key fob battery replacement. Anbody knows which battery to buy?
I was wondering if anybody can help me... My lock and and unlock button is not working on my diamond shape key fob remote. I have seen the how to replace the remote battery your self videos but i do not see what model of replacement battery that i need to replace it with.
Does anybody know the name and model number of the replacement battery and where it can be found? This would be a aftermarket purchase of course.
