Print off any picture you want, then spray paint a piece of wood black, cut the picture to match the size of the wood. Using mod podge coat the wood then lay the picture on top. Once it has dried thoroughly, use sandpaper to rough up the edges, then put a layer of mod podge over the picture.
step 1 was to apply good ole Elmers Glue to the key. Step 2 Shake glitter onto key. Let dry for a hour. Repeat steps 1 &2 for the back side of the key One might ask, how do you keep the glitter from coming off the key? SEAL it with nail polish top coat sealer!
