It most certainly is pickable, but it's a question of your level of skill, and the amount of commitment you're willing to put into learning to pick it. IF this is a one shot deal, you'd be better served calling a locksmith. If you already have some knowledge of lockpicking, you may want to browse through the Euro locks section of the site for some info on picking lever locks.

Edit: On second thought, it just dawned on me how dumb it was to recommend calling a locksmith if you've already go the key.

So that poses the question, why do you want to pick it? Is it because you enjoy lockpicking and want this to be your next conquest? Or what?
