For a gate in a fence, where a person on the street-side cannot access the latch on the yard-side. A lock-assembly is fixed to the gatepost on the street-side, and a latch-assembly is fixed to the yard-side. A cable passes through the gatepost, and connects the assemblies. The latch-assembly is a more-or-less traditional gate latch. The street-side lock-assembly includes a lock-base and a lock-cover, which are relatively openable/closable in a clamshell mode. A combination-lock locks the cover to the base, unlocking the lock-assembly enables a street-side person to open the cover. The opening-movement of the lock-cover is cabled to the latch-lever, unlatching the gate and enabling the gate to open.
