Understanding the Transponder Key System
Before you begin the programming process, it’s important to understand the basics of the transponder key system. A transponder key is equipped with a small electronic chip that communicates with the vehicle’s immobilizer system. This system ensures that only keys programmed to the specific vehicle can start the ignition. Without proper programming, the key will not function, providing an extra layer of security for your Toyota.
