Yeah... Probably doesn't matter where. You could always call a local place up and ask. Dealership would probably charge more than it's worth anyway. Especially mine!
My dealership charges like... $3000 for the TXS Stage 1!
I would go to a locksmith not just a place where they put the keys into one of those duplicator machines. I can not tell you how many times it took Wal-mart home depot and the like to get a house key right for me. It would really suck to have them mess up a 25 dollar key.
Home Depot does it. That's where i got mine done. There's two kind of cutting method. One is manual (they use a machine still to cut but the cutter has to move the cutter by hands) and there's the automated one. The only way they can do it is by manual method. It still only takes about 30 seconds. They guy who did it for me charged me $1.30.
