Hi all, my 2014 Leon key fob has popped up saying i need to change my battery, instead of getting batteries straight away i thought id just use my second key for the time being, only a week of use and now the battery needs replacing on this one.. I know how to swap the batteries over, i just wanted to know do i need to re-program the keys afterwards? I have seen you can do this via putting the fresh key in the door with the programmed key in the ignition.
Thanks in advance
