A dual lock device by using a slide mechanism includes an upper key housing(180) and a lower key housing(100). The dual lock device further includes an upper key device(190), a lower key device(110) and a sliding module. The upper key device(190) is attached to the upper key housing(180) to open the upper key housing(180). The lower key device(110) is attached to the lower key housing(100) to release the lock of the door. The sliding module opens the upper key housing(180) by authenticating the key input value inputted to the upper key device(190). And, the sliding module closes the upper key housing(180) after the key input of the lower key device(110) is completed.
