Are you positive it's only a 4 pin? Not trying to be smart or anything, but it looks like it may be five. Being that there's a plate like that, it should be removable.
I'm also guessing again but it appears that the padlock is already unlocked. You may want to have a look around the edges of the keyway and see if you can view the retaining device.
I would bet that there is a way to remove that plate, but without more information (which I couldn't dig up either) my only suggestion would be to drill a couple of small explorator holes (and I'd spend more time digging for info if I were you.)
If you've seen the bottom of an American 1100 series padlock, or even the rekeyable Master padlocks, you'll get an idea of where to drill. Use the smallest bits you have just in case though, if you decide to go that route.
