What are the reasons for the car key not responding when starting the ignition?

[DeColeman]

The reasons why the car key does not respond when starting the ignition: 1. The car battery is low on power: First, check the car battery. If the car battery is completely drained, you need to find an external power source to jump-start the car; 2. The car's ignition system has a problem: Check the car's ignition system to see if there is power in the wire entering the ignition switch; 3. The car's steering wheel is locked: Place one hand on the steering wheel and use the other hand to turn the car key back and forth. This will quickly start the car; 4. Circuit issues: Faults that cause the car not to start or respond include blown fuses, open high-voltage coils, open low-voltage circuits, detached central ignition wires, leaking distributor heads, and damaged spark plugs.
