Problem: My keyfob stops working intermittendly. It is quite annoying to stand outside my locked van, deperately pressing the unlock key and nothing happens. Fortunately, after a few minutes, it seems to work again. So I thought it was time for a battery change and followed your procedure. Very strangely, the keyfob does not work with a new battery at all, only with the old one. Any suggestions? (My fob looks exacly like the one in the video.)

Did you ever get this sorted? I have exactly the same issue with a new battery nothing worked put the old one back in and it worked!
