I went through a storm, on replacing my original keys. You might have better luck.
Bought a set online. Once in my hand, took 'em to a few locksmiths, and they would NOT cut them. They would only cut 'their' blanks. At one, I even had to special order from their supplier. Trunk key still didn't work, after it was cut.
New outfit, around here, named 'Lock Doc', so I dropped in. They had the blanks in stock, 5 minutes later, I had a good trunk key!
