The renowned Audi "switchblade" key combined a laser-cut blade with a remote fob. These secrets introduced an immobilizer chip (transponder) buried inside the plastic head. Even if the blade is cut completely, the car will not begin unless the automobile's ECU recognizes the particular chip.
3. Audi Advanced Key (Smart Keys)
Most contemporary Audi automobiles make use of the "Audi Advanced Key." This system permits keyless entry and push-to-start ignition. These fobs interact with the car by means of distance sensors and high-frequency radio waves, needing advanced software application to program.
