The lock assembly has a lock housing assembly, a driven assembly and a lock core. The driven assembly and the lock core are mounted in the lock housing assembly. The driven assembly has a connector and is selectively engaged to the lock core to allow the connector to be rotated to lock or unlock an object. The connector is able to lock two objects together or can connect an object to a stationary fixture with an optional cable, and the connector can be changed so a lock manufacturer can use this lock assembly to make many different kinds of locks.
