What are the reasons for no response when turning the key to start the car?

[CharlotteMarie]

There are several reasons why the car does not respond when turning the key to start: 1. The ignition switch is not properly engaged or is damaged. 2. The wire from the ignition switch to the starter relay is disconnected. 3. The starter's fuse box is burned out. 4. The starter relay is damaged. 5. The starter is damaged. 6. The remote control is locked. 7. For automatic transmission, check if it is in the correct gear, and inspect the starter relay and motor issues. For manual transmission, check the clutch and ignition switch problems. Solutions are as follows: 1. First, check if the car battery has power by turning on the headlights to see if they light up. 2. Listen for sounds when starting. If there is no sound at all but a clicking noise, it indicates the starter solenoid is faulty. Replace the starter or the solenoid. 3. If there is no sound at all, it might be due to worn-out carbon brushes. You can replace the carbon brushes or the starter, but also check the fuse, starter relay, ignition switch, and starter, as these could also be the cause of the problem.
