Abstract: A lock assembly has a housing, a cylinder, a main adjusting pin assembly, a sub-adjusting pin assembly and multiple locking pin assemblies. The housing has multiple sets of pin holes, two main adjusting holes and two sub-adjusting holes. The three holes of the sets of pin holes are respectively referred to as a changing position, an open position and a lock position of the lock assembly. The cylinder is rotatably received in housing and has a main adjusting hole, a main adjusting cavity, a sub-adjusting hole, a sub-adjusting cavity and multiple pin holes. The adjusting pin assemblies are mounted respectively in the main adjusting holes and the sub-adjusting holes in the housing and the cylinder to selectively block the rotation interface of the lock assembly. The locking pin assemblies are mounted respectively in the pin holes. Accordingly, the lock assembly is changeable to fit with different keys.
