Abstract
A lock device is achieved, which can prevent a battery, for supplying power to a microcomputer of an electronic control unit, from going flat by reducing the consumption power of the microcomputer, said lock device provided with a lock mechanism which holds an opening-and-closing body, for an opening in a vehicle body, an electronic control unit which operates in a microcomputer normal power mode or a microcomputer power-saving mode; and an open-state detector which detects the state of the lock mechanism. The electronic control unit transfers from the microcomputer normal power mode to the microcomputer power-saving mode when the open-state detector detects that the lock mechanism continuously remains at one of the opening state, the half-latched state and the fully-latched state for a predetermined period of time when operating during the microcomputer normal power mode.
