The Audi A6 is an executive car made by the German automaker Audi AG, now in its fourth generation. As the successor to the Audi 100, the A6 is manufactured in Neckarsulm, Germany – and is available in saloon and wagon configurations, the latter marketed by Audi as the Avant. Onboard manual programming for keyless entry remote fob smart keys is not available on the A6, meaning that special equipment will be needed to program a keyless entry remote fob smart key.
