A dual padlock includes a shell, a bolt, a button, a combination lock core, a key lock core, and a linking element supported on the shell. The key lock core is inserted in the button, rotatable relative to the button, and moveable linearly along the button. The linking element is moveable by the key lock core when the key lock core is rotated relative to the button and when the key lock core moves linearly with the button. The bolt is moved by the linking element when the linking element is moved. The bolt shuts the first opening of the shell when the bolt is in a closing position. The bolt opens the first opening of the shell when the bolt is in an opening position.
