Hi guys, I hope you can help me save a few quid. My keyfob battery was running low so I changed it (as I have done several times before) but this time it hasn’t worked since changing the battery. I wondered if there’s a way to recode it without paying Audi £75. The worrying thing is the battery in the other key is getting to the end of it’s life and I don’t want to end up with none working.
