What Is a Transponder Key?
A transponder key contains a small electronic chip in the head of the key that communicates with your vehicle’s immobilizer system. Without the correct chip, the car will not start — even if the key blade is cut correctly. Our transponder keys come with the correct chip pre-installed for your specific vehicle.
