Audi A4 2009 how to sync fob after battery change

Hi,
I have an Audi A4 2009, I change the battery in my key and now I can’t lock or unlock my doors. How do I sync the FOB so that I can lock And unlock my doors again remotely. I’d really appreciate if someone could help me with this as I’ve tried everything. Thanks so much.

Help PLEASE

Any help on this topic would be greatly appreciated. I'm VERY new to audi and recently experienced the same problem. Although in my case my fob was outside the area of oporation for a period of about 2 weeks while undergoing repairs if that makes a difference. I've also searched and searched other sites,Google,Bing and what have you and can't seem to find a straight answer for the B8. Everything pertains to B6/7. The car also didn't come with an emergency key or a second fob.
