Alternative electronic and keyless mechanical single lock control

Abstract

A lock for an access door having an electrically powered electronic smart lock control and a keyless mechanical lock control, and a single locking bolt element. The single locking bolt element is made movably operable, to permit opening of the access door, with either of an electronic code entry via the electrically powered electronic smart lock control or a mechanical code entry via the keyless mechanical lock control. The mechanical lock control, with mechanical code entry, thereby provides a fail-safe back up for keyless entry through the access door in the event of electrical failure on the electronic smart lock.
