I'll second Deansbimmer's recommendation although I didn't end up using them. I got a smokin deal from my local dealer on a master key, about $130 + tax.

UAS was around $200 including shipping for 2, I ended up with the dealer just for convenience but I wouldn't hesitate to use them. And btw, if you want, they also sell a very nice high quality flip key option (very convenient for in pocket storage) for about $30 more I think.
