I just bought one of those switchblade style 4 button fobs and I got it cut at a locksmith and programmed it myself in under 5 minutes. It's pretty sweet, I have been playing with the switchblade trigger thing all day.
Only problem I had with it was the blank blade is really long and it took the locksmith guy a bit to figure out that you can cut the key while the fob is bent. That helped it out some.
