Abstract
A system may include a lock assembly having secured and unsecured conditions and having an opening for receiving a lock actuating object. An access restriction element may be positionable with respect to the lock assembly to affect access to the opening of the lock assembly. The access restriction element may have at least two conditions, a blocking condition in which the access restriction element at least partially obstructs access to the opening of the lock assembly and an access condition in which the access restriction element is configured to permit access to the opening of the lock assembly. The system may also include an access detection assembly configured to detect attempted access to the opening of the lock assembly by sensing changing of the access restriction element from the blocking condition to the access condition.
