I've used Bill's on numerous occasions for key duplications, and changing locks; fairly straightforward stuff. On my last visit they blew my mind. I needed a key for my 1990 Saab 900. Bill's had the Saab specific key blanks, which were no longer made. Then they manually cut a key based on a code that I got from the dealer (who couldn't get me a key). The keys worked perfectly, which is more than I can say for the rest of the car.
Will definitely use them again!
