Master Lock Magnum series - M5

[subver]

So I got this lock at Home Depot while picking up some pick making tools. Anyway, I'm just wondering about the tension. It seems like the keyhole has a spring which makes it hard to turn, but you can turn it with force, past the spring, where it stops again. How should I go about using my tension wrench? Should I still just use very light touch, or should I turn it enough to get past the spring where it stops again?
Oh, also, I know there are 4 pins, but are any of them security?
Thanks!

Fight the spring till it binds, then nip a bit of the tension off and have a feel around.

Cool, thanks. I'm stupid and accidentally bought the lock without a key (it was ripped off) - I guess it's not completely important, but it woulda been nice to see how the key rotated, and see the pin heights
I'll probably return it for one with a key, but in the meantime I'm still going to try and pick it
Thanks for the tip, I will try that. Is the spring there as an anti-tension wrench type of device? I mean it just seems like if you're applying enough tension to fight the spring, it would be too much once you get to the binding point, but I guess I'll just have to be even more sensitive in this lock.
Thanks

Shouldn't think the spring is anything security related. Most padlocks are sprung to return the key back to the position where it can be extracted with the shackle still open. Then you have key retaining padlocks which won't return the key to the extraction position until the shackle is closed.

Most locks (especially padlocks) open to the right, clockwise.

If you got this lock at Home Depot while picking up some pick making tools
i never seen home depot selling locks with no keys
if anything the keys are always attach to the lock by a plastic strip or in the plastic case
anyways this Master Lock Magnum series - M5 you should not have any problem picking this lock
just try light tension sometimes you just need to pick the first two pins and it will pop open
i got one Master Lock Magnum series - M5
and one Master Lock Magnum series-M15 boths of them open the same way hope this helps.
