I have a laminated Chinese padlock I bought at wally world. The shackle on this lock is longish at 2 1/8" the lock body is about 1 5/8" wide. The only markings on the lock are "Hardened" on the shackle and "40mm Made in China" on the bottom. The problem I'm having is I can't get any of the pins to bind. Not a single pin. I've tried putting my tension wrench in various places, top of key way, bottom of key way, tried applying tension up and down. I've tried varying the tension from just laying my finger on the tension wrench up to putting a large bend in the wrench. Nothing works. I'm not upset that I can't open the lock, but I would hope to get at least one pin to bind.
