This is kind of a PITA, especially of the grille is still on the car. When the star is installed, you turn them metal piece on the outside of the spring and it snaps in. So you'll have to get a good sized pair of pliers and pull down on that metal piece and turn it. The wide ends should point towards the front and back of the car. There are little grooves that that metal piece fits in...make sure you get it in there or else you won't be able to get it out. It's kind of hard to explain...but good luck!
