Understanding Transponder Keys

Here at We’ve Got The Key, we back ourselves on all thing’s keys, but we understand that whilst many people own a pair, they might still need to learn the inner working of keys. In this article, we tell you what a transponder chip is, how it’s vitally important for all keys and how our locksmiths can use them to cut and code your spare or new keys.

What is a car transponder chip, and how does it work?

A car transponder chip is a small electronic device fitted on the inside of a car key or fob. The chip is designed to communicate with the car’s immobiliser system, allowing the vehicle to be started only with the correct key.

When the key is inserted into the ignition, the car’s immobiliser system sends a radio signal to the transponder chip in the key. The chip responds with a unique code to the car’s immobiliser system. If the code is correct, the immobiliser system will allow the car to be started. If the code is incorrect or missing, the immobiliser system will prevent the car from starting.

The transponder chip works by using a small radio transmitter and receiver. The chip contains a small microchip that is programmed with a unique code. When the chip receives the radio signal from the car’s immobiliser system, it uses an internal antenna to transmit the code back to the car. The car’s immobiliser system then checks the code to ensure it is correct before starting the car.

Overall, car transponder chips provide additional security for modern vehicles, making it much more difficult for thieves to steal cars.
