I sure tried to install the lock myself. But there was no way in the world that I was going to figure the damn thing out. So I looked up locksmiths and stumbled across these people. I gave them a call, expecting a horror story, but instead they provided excellent service and were done rather quickly! They didn't charge me too much for the mess that I created either, which was the best part of the whole experience. Overall, they did a very good job and I would be happy to use them again.
