yep I have also figured it out. The buttons slip into position if they are to be pushed, or grind if they are not to be pushed. The "opening" must be held down while you try each button. I had not tried to pick one when i posted the message, was just curious. Since then I bought one, and picked it in 30 seconds.

I would have to add that wheel and button locks are the crapest locks on the market. They can be picked with no tool (or just a feeler guage for the master 175 padlocks). The wheel locks (black body, gold coloured wheels and shackle (sorry no pic, couldnt find on masterlock.com I wonder why not?) i picked first go in about 10 sec. It would be more safe to strap the thing up with Ductape!

It would take longer to cut the tape of than to pick the lock!
