That one is about as small as you can get because of the length of the key. It has to hide down the side of the fob. I got the key cut at the store and used a Dremel to shape the end part that goes into the switchblade key fob. It wasn't very hard. I traced the key blank that came with the fob. You need a steady hand and just cut a bit and see if it will fit. Then shave a bit more and a bit more until it slides in nice and then put the tiny screw into the side to secure it and you're good to go.
