The front is held on by a screw. I had to remove my front grill by removing several little "ship anchor looking" like clips. Someone on yotatech has a few pics of how to do it. Before I unclipped the grill I went and bought some from the dealership incase I broke some. They are really cheap so.... With regards to the back mine didn't have anything holding it other than glue so the floss took care of it.
