A motor with a shaft and a shaft axis is disposed within a housing. A lead screw has an axis and is rotatably mounted in the housing. A deadbolt linearly extends from the housing based on rotation of the lead screw. A gear set with a plurality of gears, each having an axis, is disposed in the housing and operably connects the motor and the lead screw. A circuit board is disposed within the housing and has a plurality of portions communicatively connected by a ribbon. Each portion is disposed substantially orthogonal to the motor shaft axis, the lead screw axis, and the plurality of gear axes.
