The present invention is directed to exemplary embodiments of a combination disc padlock that may include a housing, a shackle positioned within a portion of the housing, the shackle having a curved shape with a first end that is never released from the housing and a second end that may be exposed from the housing when the padlock is in an unlocked configuration. The padlock may include a mechanism or other structure formed on or connected to the shackle that facilitates movement of the shackle between a closed position and an open position. The padlock may include a reset mechanism that prevents a user from accidentally changing a combination code of the padlock when the padlock is in the unlocked configuration, thereby requiring that the padlock be put into a reset mode in order to change the combination code.
