There are two prongs in the back, one at 3 and one a 9. I used a thin flathead to get underneath and pop off the front one on mine.
You may feel more comfortable using a plastic knife or rubber putty knife to not scratch the surface underneath, but if you're careful it's not a problem.
Or you could dissasemble to inside of the hood and trunk and get at it from there. :wink
