An unexposed shackle combination padlock having a padlock body and a U-shaped laterally swingable shackle wherein the padlock body includes relatively reciprocatively movable outer shell and core portions with one of the shackle legs journaled in the core portion and the other leg swingable to open position only when said shell and core positions are shifted from a relatively alined to a relatively displaced position. Two separate locking systems are provided, including a combination dial system having wheel assemblies and a fence member for selectively locking the shell and core portions against relative movement, and a key locking system is provided which is disabled from key operation whenever the dial wheels are not set on the proper combination. Either one of the combination locking system or the key locking system may be used separately, or they may be used in combination providing effectively a third locking system.
