The keyfob low battery warning appeared on the dash recently so I purchased a new battery but when fitted it showed the same warning, I then swapped the battery for the one in the spare key and that shows the same. As I am writing this I have just realized I should have just tested the spare key and not just swapped the battery so will do that tonight...any ideas?, is there a reset procedure I should be following ? The keyfob still works and I can't see it being 3 batteries that are run down especially the new Duracell one, also moving the keyfob around near the sensors makes no difference...Couldn't see anything on the search or wiki specific to this issue so thought I would post it...Thanks I need more help than most...sorry !!

Mine is doing this also, there is info on this topic. I've just replaced the battery using instructions from this video. Now it seems fine. 2017 4.4 SDV8 Autobiography in black
