Help! Car won't start

kntrider

So got up for work and the car wouldn't start.
Hadn't driven it 3 days and it showed no signs of a weak battery or any issues.

The lights, radio, horn everything seem fine.

I hit the engine start button to AC and then On, it try's to start but one click and suddenly everything is dead. It keeps doing that.

Tried to jump and trickle charge but nothing.

Any thoughts of starter or alternator or clean MAFs?

It's a 2009 6M with 55k miles.

Thanks for your help!
