A deadbolt lock and a deadbolt which will extend automatically whenever a container is locked by virtue of a rigid portion of the container engaging a trigger element extending from the end face of the bolt and causing the release of an outer bolt portion is shown and described herein. The release of the outer bolt of the bolt assembly allows the outer bolt to project outwardly and to lock the container notwithstanding the fact that the bolt has not been reset by the operator of the lock. The bolt is self-contained and can be substituted into many existing lock mechanisms of the mechanical type and into some of the existing electronic dial combination locks, to provide the auto-locking enhancement.

A combination lock and particularly an electronic combination lock used on a container that is typically housed within an enclosure having a door which further has a lock and a security switch indicating that the enclosure door has been opened may, be provided with a device to shunt a security signal around the switch associated with the enclosure door to shut off, override, or cancel the security switch signal. The lock may be provided with a shunt relay which effectively connects a signal from a voltage source to a monitor or alarm when the combination lock is opened, thereby signaling the monitor that the enclosure door was opened by an individual having the authorized combination for the combination lock. This indicates that the person opening the enclosure lock has a legitimate authorization to access the locked container within the enclosure and that the opening of the enclosure door may be reasonably ignored. Upon the locking of the combination lock and the closing of the enclosure door a brief alarm signal indicates that the combination lock has been locked and the enclosure closed.
