They only have a single key for a reason...
These are "LockOut" padlocks. They are for workers to lock dangerous things while they are being worked on to keep people safe. If they had more then one key someone else could open the lock and someone could die. They have very good 6 pin cores and also have security pins of different types and are very hard to pick. That makes them great for locksport.

For its intended purpose - safety lockout - it's pretty good. It's not coming off the machine it's locking without a key or destroying it. For hobby lockpickers like me it's great because it's got the best core Master makes. Ok, that's not saying much, but seriously the 6-pin core on this thing is actually pretty good despite having been made by Master. This lock is harder to pick than an American 1100. Which, really, begs the question why their best core can only be found in a plastic lock when they've got locks that are invulnerable to any destructive attack short of power tools that can be picked by a 10 year old. But still, I think this lock is an essential addition to any intermediate hobby lockpicker's collection.
