Abstract
A dual locking padlock having a code locking mechanism and an overriding mechanism is disclosed. The housing has a spacer as its top portion, a stack of clutches forming a middle portion and a bottom portion having holes to receive screws from the spacer for securing the housing. Dials are rotatably mounted on the clutches for changing the combination code. The housing has a spindle having a channel to store the heel of a shackle. The spindle'"'"'s upward movement allows the shackle to be pulled upward to unlock the padlock. The spindle is allowed to move upward either when a correct combination code is used or when a key activates the overriding mechanism. With the overriding mechanism, the user can open the padlock with a backup key if the user forgets the combination code, and then reset the dials to a new combination code.
