2. The Switchblade (Flip) Key
Presented in the late 1990s and utilized heavily through the mid-2010s (on designs like the A4 and A6), these keys consist of a folding metal blade and a remote fob. These contain a transponder chip that should be synchronized with the car’s immobilizer system.
3. The Smart Key (Advanced Key)
