Why won't my BMW M3 start?

I own a BMW M3 and it has been running perfectly fine until this morning. When I went to start the car, it wouldn't start at all. The lights and radio are working, but the engine won't even turn over. What could be the issue?

First, check your battery and make sure it is fully charged. If the battery is dead, the car won't start. If your battery is fine, then the issue may lie with the starter or alternator. It's best to take your car to a mechanic for a proper diagnosis.

Another possibility is a faulty ignition switch. If the switch is not sending power to the starter, then the car won't start. You can try wiggling the key and see if that helps, but it's best to have a professional look at it.
