hi all had my a6 c8 for few weeks now but was unable to unlock car few days ago, key not lighting up pressed few times then starting working, put new battery in fine for few days did the same, so thought maybe a dud Bayern so changed again and last night was locked out for 30 minutes took key apart to get in but still wouldn’t recognise key, so had to get spare key again wouldn’t work so just about to call Audi Assistances and surprise all working again both keys fine!! Any one had this issue
