Key fob buttons stopped working when battery was disconnected

[BO55 FZC]

Hi my battery was disconnected to fix something and connected again the key fob buttons stopped working. So now I have to put it in manually to lock the door and put the mirrors in. I looked at some forums how to resync it but nothing works does anyone know the proper way to do it. My spare key doesn’t have buttons on it either so can’t use that. Can I do this myself or need Vagcom any help would be appreciated cheers.

solved: it needed to be coded using vagcom although I have one keyfob and one manual key it needed to be coded that I have 2 keys and it works perfectly. I didn’t need vagcom either so works perfectly now.
