After buying a new home, I needed the locks changed. I've changed deadbolts myself before, but encountered one that had no screws visible and after a half our of aggravation, I called a professional.
The gentleman who came out was prompt, greeted me with a handshake and a smile, and went straight to work. A little bit of small talk and he let me know he is a second generation locksmith, learned from his father. He was very proficient, very speedy, and reasonably priced. It was cheaper to have him rekey my deadbolts than purchase new sets.
Highly recommended!!
