Question about 2009 Ford Focus
AFTER turning the ignition key, all led's go dead and I can hear a buzzing/humming sound.

Do you have the tow package on your vehicle? If you do it sounds like your trailer electric brake controller is shorted out (normally mounted under the dash on drivers side). There should be a fuse that controls your tow package either in the fuse panel or as an in-line fuse.
If that isn't it, then I would suggest a clamp on amp meter to help you narrow down what is draining your battery. BUT have you had your battery tested to make sure it is good?

Is your engine cranking when start, if not, the battery need to be replace.
