A two-way remote control unit includes at least one two-way remote controller provided with remotely calling and locating functions, so that a user can save the money that is otherwise needed for purchasing an additional calling device or a finder for calling or locating the remote controller, and needs not to troublesomely carry the calling device and finder around. Users can use two-way remote controllers of the same type to call or locate one another, and the two-way remote controller can be conveniently used as a finder, too.
