The dual function lock also includes a first locking mechanism within the body wherein when the first locking mechanism is locked, the shackle is in a first position where the toe of the shackle is located within the frangible element so that the shackle cannot be rotated and wherein when the first locking mechanism is unlocked, the shackle can be lifted from the first position so that the toe of the shackle is not within the frangible element so that the shackle can be rotated. Methods of using the lock and a refillable insert of frangible elements are also disclosed.
