• The Dash-Insert Plastic Fob (B8 Generation, 2009-- 2016): These keys are pushed into a slot on the dashboard to begin the engine. They consist of an intricate internal transponder.
• The Smart Key/ Keyless Go (B9 Generation, 2017-- Present): These utilize "Advanced Key" technology, allowing the chauffeur to keep the type in their pocket while starting the car with a button.

Can I utilize a key from a different Audi A4 (utilized key)?
