Why is my Ford S-Max not starting when I turn the key?

I have a Ford S-Max and I'm having trouble starting it. When I turn the key, nothing happens - no sounds, no lights. I've tried jump starting it and it still won't start. I've checked the battery and it seems to be fine. What could be causing this issue?

It's possible that you have a faulty starter motor or a problem with your ignition switch. I would recommend having a mechanic check these components to see if they need to be replaced.

Another possibility is that you have a dead battery. Even if it seems fine, sometimes a battery can have enough power for lights but not enough to start the car. Try replacing the battery or using a battery charger to see if that solves your problem.
