I called the service about 10am and told him what I wanted. He was there in one hour and finished within an hour and a half. I live in an older, established neighborhood with a lot of covenants and restrictions as to what you can do or change as far as the looks and character of your home. I had tried several times to find a replacement lock to fix my door but couldn't find one. Home Depot didn't even know what I was talking about. John from Global Locksmith Service showed up, said "Yeah, I got that." and had it fixed, matching current keys, in about 90 minutes. I know I'll be using Global Locksmith Service service again if needed.
