A crowbar, bolt cutters, and some good old fashioned ingenuity, or if you don't care about what is inside, then just blow the thing to bits.

If you know the code to it, just use the code given in the up, down, left, right format. If you mess up, just simply push down the shackle twice. If you still can't do it, try finding a narrow but somewhat stiff object, like a paperclip, pushing it below the shackle, and pushing it up. If that doesn't work, maybe try using an object like a screwdriver to lift up the middle slider and move the inside pieces until they all match with each other. If that doesn't work, try breaking the lock with some objects around you. Bolt cutters would be ideal, but you use other objects around you like a hammer. Note that if your using a hammer, you have to use the back part of it.
