To install, simple push them into place with a firm shove. If your set came with bolt covers they're the same, just sliding over the existing bolts.
Should you need to remove them, never use a screwdriver, as it'll damage your wheels. For the bolt covers, keep the removal tool handy in your glove box, and just pluck them out.
To remove the center caps, you can use a plastic pry bar or spudger to get behind them and pop them out, but be sure to not let them hit the ground.
You can also use a plastic pry bar, or even some gaffer tape to pull them out. Do not use duct tape, as that tends to leave a residue.
