Faulty ignition switch: If the ignition switch is faulty, it may not be able to send the correct signal to the starter to crank the engine. This could cause the key to go all the way in but then lock, preventing you from starting the car.
Faulty starter: The starter motor is responsible for cranking the engine. If the starter is faulty, it will not be able to engage the flywheel and turn the engine over. This could cause the engine to not start, even though the key goes all the way in.
Weak battery: A weak battery may not have enough power to crank the engine. This could cause the key to go all the way in but then lock, preventing you from starting the car.
Faulty fuel pump: If the fuel pump is faulty, it will not be able to deliver fuel to the engine. This could cause the engine to not start, even though the key goes all the way in.
Faulty glow plugs: The glow plugs are responsible for pre-heating the combustion chambers in the engine. If the glow plugs are faulty, they will not be able to heat the combustion chambers, which could make it difficult for the engine to start.
_If you are not comfortable diagnosing and fixing the issue yourself, it is best to take your car to a qualified mechanic for further inspection and repair._
