Fault Diagnosis

The key fob contains an electronic chip that communicates with Fiat's immobiliser system to ensure that only authorized vehicles can start the engine. If the transponder chip on the key fob is damaged, it won't be able to connect to the immobiliser unit, and as a result, your car won't start.
