Transponder Keys Transponder keys are the most popular type of car keys. They use a microchip to connect to the car's computer system and transmit a unique security code. These keys are designed to ward off unauthorized access, which is the reason they're so difficult to duplicate. They also cost more than regular keys. Here's a quick overview of how they function. Transponder keys usually have a plastic component that houses the microchip. The chip is similar to the normal key, but it's slightly larger than a conventional key due to the fact that it needs to accommodate the microchip. The plastic piece is affixed to the key's base and is evident when you look at it closely. The chip sends an immobilizer code to the computer onboard of the vehicle.
