Transponder Keys

What Is a Transponder Key?

Modern vehicle security starts with transponder key technology. Unlike traditional keys, a transponder key contains a small electronic chip that communicates with your vehicle's computer. When you insert the key:

1. The chip sends a unique security code to your car
2. Your vehicle's computer verifies this digital signature
3. Only after verification will the engine start
