I release the tension and I have hear the pins dropping. The problem I think I'm having is their are 2 pins inside which just do not bind. So you have to lift them and some how keep them both at the sheer line at the same time which is impossible.
Some of the binds bind and I hear the click, but the lock just doesn't turn and I think it's because 2 of the pins just refuse to bind no matter how much tension I apply.
The lock you have is a Squire Stronghold 35, 37 or 39 depending on the size. I can't tell from your pic, but it doesn't matter. The money spend on this padlock is for a durable outside lock that can stand some corrosion.
There are no security pins in them. Squire put them in their 6 pins, but not in their 4 pins. This lock is pickable, but as ARF-GEF has well said perhaps this one has just got you on a bad day, or your technique needs refining. I also throw a lock in the naughty box if it's twisting my melon. I'll get the sucka in the end. Move to a different lock for awhile.
As well as all the completely valid advice the guys above me have given, there's 2 things not mentioned, and the main one is over-lifting. I thought this could be a possibility since you mention that you can hear the pins re-setting when you take the tension off. When I get frustrated with a lock, this is common to me. Try not to be so heavy with your pushing the pins, but rather let off a little on the tension to help you move them.
In addition, the pin you set before you have 2 remaining that won't set is your problem. It's either not set correctly or over-set.
Be gentle with it. Take your tension wrench out, and feel how strong the springs are as you push down with your pick. Then with a little tension on, feel them out individually and see which one puts up more resistance to your push. Note him, and push gently until it moves, keep going until you feel movement/click in the pick and/or tension wrench. I think you're fully up to speed on this, but I find it useful to remind myself sometimes.
By the way, this won't shim as it's ball locking.
Keep trying, dude. Gentle practice practice, practice. Locks are hard as nail, but they don't require a huge force to pick them. They require gentle, firm awareness from the side of the picker.
Hope this helps. Good luck.
