Abstract
A cylinder lock manufacturing method wherein a plurality of cylinder locks differing in place of use but using a common key for their unlocking are taken as a group having a specific key code assigned thereto. The inner members and outer members of cylinder locks are assembled into respective cylinder locks continuously for one group after another with change of the key code. A key for each group of the locks is notched synchronously with the cylinder assembly process. The cylinder locks and the key so produced through the above processes are combined as a set.
