You need to get under the clips and free up the trim. My shop "metal guy" had a neat tool, a hacksaw blade with about a 3/32" lip turned up 90 degrees on a cut end. Hooked in under the clips quite well to allow you to pry the clip of to free the trim.
This is the "official" tool.

Take your time, be careful, they can be stubborn but you don't want to bend the trims, which is not too hard to do.
Getting them back on is pretty easy, I am not sure of the factory order, but I do the top first, connect the two and align, then pop them in. I find the heel of your hand gets most in, maybe a soft cloth wrapped on a small piece of wood and a few light taps with a dead blow. Biggest mistake I've seen is people hamming on them and denting them badly.
I then test fit the sides to get the proper height to match the lower, and put them on, then lower last. it is a bit tricky to get the pieces all clipped together and in, but that is what worked for me...
