Don't know if you have to remove the front facia, but if you do and it's anything like the back one it's easy. There are screws in the wheel wells that have to come out, then there might be some in the engine bay and then you pull it out of the snaps. I'm assuming you are trying to change the fog lights to something different/better? I'm assuming there is a way to get the lights out, but maybe it's just bulb access for burnouts.
