hello sorry for the delay, I hope I'm not wrong and a 13 key, as regards the recording of the battery it would be correct to record it in audi, but if you don't record it, nothing changes. My audi q5 year 2009, I didn't register it and it works great
Hello, sorry for the delay, no I have not reprogrammed anything even if I have a software to program. My audi q5 and from 2009 a bit old car. Everything works fine
