Try yelling at the lock really loud - it looks like that might work on this lock
If it is a wafer lock, then you can't "pick" it. There are no pins or wafers to manipulate.
To pick this lock you just need to file a piece of metal so that the tip matches the shape of the tip of the keys and the rest of the metal is no thicker than the thinnest part of the key. That should open every lock of that type.
