Kinds Of Audi Keys

Flip Keys (Switchblade Style): Found on older models (approx. 1997-- 2010), these function a retractable metal blade and buttons for remote locking/unlocking.Smart Fobs (Plastic Fob): Used in the mid-2000s to mid-2010s, these keys are placed into a dash slot to start the engine.Audi Advanced Key: This is the present standard for many designs. It permits keyless entry and push-to-start ignition. The car finds the key's distance and opens when the handle is touched.Audi Connect Key (Digital Key): The latest frontier, enabling select mobile phones to function as the primary key through the myAudi app and NFC technology.Comparison Table: Audi Key GenerationsKey TypeApproximate EraPrimary FeatureStarting MethodMechanical/Flip1996-- 2008Remote Central LockingMechanical Turn in IgnitionAudi Smart Key2009-- 2016Integrated ImmobilizerPlace Fob into Dash SlotAdvanced Key2017-- PresentDistance SensorsPush-Button StartDigital Key2020-- FutureSmart device IntegrationNFC Reader/ Phone AppHow the Audi Immobilizer System Works
