Skoda Fabia keys

I have used the search function on here and I have tried to resync the key following the manual and using vag-com.

However the 1 key still won't work, when I tried to reprogram it with vag-com when I changed it to two keys it saved it but then went back to 1 key. But both keys made the horn bleep so I'm not sure what's going on.

Is this going to involve taking it to a stealer and getting them to sort it? :/
