Why does my Audi A4 not start when I turn the key?

I have had my Audi A4 for a few years now and have never had any major issues with it. However, recently when I try to start the car by turning the key, nothing happens. No sound, no lights, nothing. What could be causing this issue and how can I fix it?

Have you checked your battery? It is common for car batteries to wear out over time. Try jump-starting your car or get your battery tested to see if it needs to be replaced.

It could also be an issue with your starter motor. If your battery is in good condition, but the car still won't start, it may be time to have your starter motor replaced.
