A Chronology of Audi Key TypesMechanical Metal Keys (Pre-1995): These utilized traditional lock-and-key cylinders with no electronic parts.Transponder Keys (1995-- Early 2000s): These keys consisted of a small passive chip that the car's immobilizer system would scan before enabling the engine to start.The "Switchblade" Remote (Late 1990s-- 2010s): Perhaps the most renowned Audi key, the flip-out blade combined remote main locking with a physical key.audi Car keys (https://aabaas.com/) Advanced Key (2005-- Present): This presented proximity-based entry and push-button start, allowing the driver to keep the type in their pocket.Audi Connect Digital Key (2019-- Present): The newest iteration uses Near Field Communication (NFC) via a mobile phone to unlock and begin the vehicle.Understanding the Audi Immobilizer System
Audi's security is centered around the Immobilizer System (generations IV, V, and V+).
