What is a Transponder Key?

A transponder key is a type of car key that uses a small microchip to communicate with your car’s immobilizer system.

If the signal is recognized by the immobilizer system, the car will start.

Before you begin programming your transponder key, you’ll need to gather a few tools and materials. Here’s what you’ll need:

✔ A blank transponder key
