I have been studying deadbolts and door knobs and have a fair understanding of how it goes and now I was wondering about the type of locks on commerical doors, the business world would use here in the US. Where do I start? Are these called mortis and rim locks? In my travles at work I have found old locks on houses that are seperate from handle and unscrew, on the back they hace 2 small screws that hold a KEY I will call it because I dont know the right word. The things I learned so far is the top pins must be loaded from the inside and the follower is a differant size than I use, but best of all I see where the old locksmith scribed the code on the back. I tried to find these lock manufactures but can't . they are Welch, Sargent, Reading. I have heard of Sargent but these are to old for their web site. So where do I start my studies of commercial locks. I know there are a couple screws on the edge that hold it to the frame and that it has a Schlaeg key.
