Hi all I have an Audi 2013 s6 Quattro I have recently changed my battery in the key and now I can't start the car (no ignition just immobiliser and push start/stop) the dash keeps displaying key not recognised when I put the key against the imobiliser and press engine start I've tried to get it towed but the car is stuck in park since I can not start it I can lock it with the key Manuely so the car is safe but I'm not sure how long it will last sitting on the street before some kids try to mess around with it as I live in a quiet coltersack I was wondering if any of you lovely people could help me try and get it started or have any tips or advice that could come in handy is there anyway I could switch off the immobiliser or get it started so I can take it to the dealer ship or atleast get it on the back of a tow truck it's really stressful! Kind regards my fellow Audi fanatics 😁
