One of the main problems that can compromise the ignition of the car is the malfunction of the key code. All keys indeed have a unique code that allows the ECU and the starter motor to recognize the key and therefore open the vehicle, all in a matter of seconds.

However, if the code is not recognized, the car will not only not unlock but will not be able to start the engine. The main causes of malfunction are related to the key itself, which may require reprogramming or replacing the battery.

Sometimes the problem is related to a malfunction of the ECU that releases electromagnetic waves that do not allow the key to function, in these cases it is necessary to reprogram the ECU.
