Abstract: A lock control device controls a lid lock that locks a lid of a vehicle, the lid being opened when energy is replenished in the vehicle. The lock control device includes a time measurement part that measures elapsed time from a point when a door lock of the vehicle is switched from an unlocked state to a locked state when the vehicle is stopped, and a lid control part, which maintains the lid lock in an unlocked state until the elapsed time reaches determination time, and switches the lid lock to a locked state once the elapsed time reaches the determination time, when the door lock is switched from the unlocked state to the locked state when the vehicle is stopped.
