This has happened twice to me already in a week.

I would parked waiting for someone so I roll down the Window and turn the car off. Then when i try to start the car, Nothing happens, No Crank Noise. There is Battery life cause the radio and all the dash lights come on.

I get the car to start after about 10-20 mins of putting the key in and out, trying to start it.

Could it be the Anti-Theft System kicking in?

Different subject, also noticed a humming noise coming from the front of the car, what could it be?

I have a 2007 Hyundai Santa Fe GLS

Sounds to me like your starter is out. This happened on my old maxima and had the same exact symptoms as you. The humming noise you hear is the starter trying to push out, but it is no longer able to properly. Pretty easy fix, and relatively cheap (Around $65 OEM)
