System including audit enhancement assembly with enhanced sensing capability

A system may include a lock assembly having a shell and a plug rotatable with respect to the shell and a lock operating object for operating the lock assembly including a key. The system may further include an audit enhancement assembly configured to facilitate creation of an audit trail of operation of the lock assembly by the lock operating object, and may include a motion sensor configured to sense rotational motion of the lock operating object and/or the plug of the lock assembly. The audit enhancement assembly may include processing circuitry in communication with the motion sensor, and memory circuitry in communication with the processing circuitry to receive and record a value derived from a motion signal from the motion sensor and a temporal value associated with a motion signal event.
