Car won't start - is it a battery issue?

My BMW 6 Series won't start, could it be due to a dead battery? How can I troubleshoot this issue?

It is possible that the battery is the issue. You can start by checking the battery connections and ensuring they are tight. If that doesn't work, try jump starting the car.

Another possibility could be a faulty starter. You can try tapping on the starter with a wrench or hammer to see if that will make it work temporarily. If it does, you may need to replace the starter.

Have you recently had any work done on the car's electrical system? If so, it could be related to that. Check all the connections and make sure they are secure.
