Hard to Duplicate

The padlock comes with 3 keys which is important as the keys are too unique to duplicate easily.

Hard to be Cut Off

The lock is built to resists being picked by a shim (along the sides of the shackle), and also has a unique internal mechanism that is more difficult to pick. And, because there is a metal barrier that blocks the shackle, it is also more difficult to clip with bolt cutters.
