Ok let me confirm, because I was messing with it again today. The Abus (Uhaul stamped on it) 85/40 is a bit hard because it has mushroom pins in it according to the Abus website on this particular lock.

I don't have the key to it, not sure if I ever did, cause I believe it was my brothers from years ago.
Why did I still have it? Good question, lol, and the answer is, I have no idea! Guess it was waiting for this moment.
