When the brake pedal is depressed in Park, you'll here a subtle click under the shift knob. That's the latch solenoid activating, allowing the shifter. Being electrically-powered, obviously, nothing is going to happen with a dead battery. So, the shifter knob needs to be removed by sliding the chrome trim ring down and the T-15 set screw that secures the knob to the stalk has to be loosened to allow the knob to be removed.
After that, it's easy to pry up the center trim cover (from back to front) with a plastic trim tool and lift it just enough (or remove it completely after one internal connecter is de-mated) to raise the white plastic latch pawl with a finger to allow the shifter stalk to be placed in Neutral. This sounds harder than it is. The whole process takes less than two minutes.
