<p>A key unit includes a transmitter for remote actuation of a lock and, in a common housing, a mechanical key for mechanical operation of the lock. The mechanical key is held within a key compartment in the housing and, when a trigger button is depressed, pivots to an outwardly extending working position on a circular bearing portion. The cover of the housing is held to the lower portion at one location by a bayonet connection which enables the cover to be pivoted to a position for access to the battery compartment in which batteries are contained for the transmitter. A lock connection spaced from the bayonet connection couples the cover to the lower housing portion when closed, and a removable locking screw is provided to hold the cover in the closed position.</p> |
