What Are the Reasons for No Power or Response When Inserting the Car Key?

[Chad]

The reasons for no response when inserting and starting the car key include a depleted car battery or issues with the ignition system. First, you need to check the car battery. The specific method is to use an external power source to jump-start the car. If the car can start through jump-starting, it indicates that the battery is depleted, and you will need to charge the battery or replace it. You should also inspect the car's ignition system to see if there is power in the live wire entering the ignition switch. If there is power, it means the ignition switch is functioning normally; if there is no power, it indicates a faulty ignition switch. Additionally, a locked steering wheel can also prevent the car from starting. In this case, place one hand on the steering wheel and use the other hand to turn the car key back and forth. The car should start quickly, and this situation is not a fault and does not require repair. Electrical circuit issues can also cause the car to fail to start. Common faults include blown fuses, open circuits in the high-voltage coil, open circuits in the low-voltage circuit, detached central ignition wire, leaking distributor rotor, or damaged spark plugs.
