Will the key switch ignition module keep a truck from starting bc it's messed up

Hey, my name is Dusty, and I'm one of the auto experts with RepairPal's Car Genius team. I'm here to help! A faulty ignition switch module can prevent it from starting, even after changing the key. If the ignition switch doesn't work, it could stop power from reaching the starter motor, fuel pump, or ignition system, keeping the engine from starting. Some vehicles have a security system linked to the ignition switch, which could prevent the system from recognizing the new key and disabling the ignition. If you suspect the ignition switch, replacing it might solve the problem. If the issue persists, having a professional diagnosis is a good idea.
