This sounds like a problem with the electrical system of the car. It could be a problem with the battery, alternator, or a blown fuse. It's also possible that there is an issue with the ignition switch.

As an owner you can do some basic diagnostic steps before taking the car to a mechanic:

Check if the battery terminals are clean and tight. If they are corroded, clean them with baking soda and water.

Check the alternator belt to ensure it is tight and not broken.

Check the fuses, If a fuse has blown it will need to be replaced.

You can also try jump-starting the car to see if the battery is the issue.

You can also check your car's owner manual to see if there is a way to reset the ignition switch.

For basic diagnostic steps on your car, you will need the following tools:

A voltmeter or multimeter to test the battery and alternator.

A wrench or pliers to check the tightness of the alternator belt.

A fuse puller or needle nose pliers to check and replace fuses.

Jump leads or a portable jump starter to jump start the car if the battery is dead.

Additionally, it's helpful to have a car owner's manual so you can refer to it while doing the diagnostic steps, as it may have information on how to reset the ignition switch.

Keep in mind that these are just basic diagnostic steps, and more complex issues may require more specialized tools or equipment for repair

If none of the above steps resolve the issue, it is best to have a professional mechanic take a look. Some electrical problems can be dangerous, and a knowledgeable mechanic will be able to diagnose and repair the problem safely.
