The Comprehensive Guide to Audi Car Keys: Evolution, Technology, and Maintenance
For decades, Audi has positioned itself at the leading edge of vehicle innovation under the slogan "Vorsprung durch Technik" (Progress through Technology).

Modern Audi vehicles generally use the "Advanced Key" system. This is a proximity-based innovation where the chauffeur does not require to place a key into a slot. As long as the fob remains in a pocket or handbag, the doors unlock via touch sensors, and the engine starts with the press of a button.
