Help with Master No. 570

[FFVison]

So, I got a Master 570 perhaps a week ago. Sorry, I don't have any pics of it up right now. I am having difficulty picking this lock. It seems like a pretty strange lock, actually. The plug seems to turn with the slightest tension. I know that I have seen some people compare this lock to a Master No. 532, though I don't see too many similarities. The key seems to turn VERY easily compared to other locks. It doesn't have a spring behind the plug, like many other Master locks. I pick this lock from back to front and it seems to make sense all the way through except when I hit the front most pin at which point, the plug turns and I get a false set somewhere. Now, I let off the tension a little and try to push the pins up to find out which one(s) are false sets, but nothing seems to work. I do have one suspicion though. I look at the key and it looks like pins 3 and 4 are very deep cuts and the 5th is a shallow cut. I tried getting a long hook in there, but I can't get it in there without it hitting the other pins. Any suggestions?

If you've gotten it to false set, don't let off tension. Go in and find the pin that pushes back against you on the tension wrench. Then, and ONLY then (while it's pushing back) should you let up on the tension and only as much as it is pushing back. It may seem counter-intuitive but, you actually have to let the plug rotate back (or be pushed back) as you're setting that pin.

You're probably up against one or more spool pins. If you lose some other pin sets while setting this one, don't worry about it. I've got a 5-pin lock with 5 spools and it's like 15 steps to pick it and one pin gets picked 4 different times it seems. You just have to do what the lock tells you. Your lock is telling "You're almost there."

I personally love spool pins for this very reason. Except for my Brinks shrouded. That S-0-B. I still like it but, it is a bear to get open in less than a minute. Everything else I own I can pop in less than 30secs, including my other Brinks "Max" security locks. That shrouded S-0-B likes to be a pain in my butt.

If you want to see an example of what I'm talking about with letting the spool pin push back against your tension wrench, take a look at my #911 video. http://www.youtube.com/user/JohnOPSEC Pay careful attention to when I'm picking the 4th and 5th spool pins. You can really see then push back against me and rotate the plug the opposite way you would think.

yeah, I have tried that too. I think I just got a difficult lock. I have picked spool pins before with a little bit of problems, but I think the problem here is that the frigging inner-most pin, the fifth pin, needs to be lifted higher and my fourth pin just isn't letting me. Any suggestions? any pick types you would recommend? I have picked some of those brinks max security locks too. They are fun. I have one that's laminated that looks to be about the same size and look as a Master No. 5, but it's a lot more difficult. Anyway, I used to be able to pick that one VERY easily, but now, it just doesn't want to pop for me. The key still works though, so that's a good thing. I also have a Brinks R70 which is just fun as hell to pick. Once you realize that you have to apply a crapload of tension on the wrench to pick it, that lock is as good as picked. I actually had more difficulty picking my Master 40 (looks like similar casing) than I had with it because I have to actually be quite a bit more conservative with my tension on that one. But yeah, I think after trying all kinds of stuff to this lock, I think it's just that fifth pin stack. Only reason I suspect that is because of looking at the key's cuts. So, I guess I need help with that.

Also, to any moderators, would this question be best suited for this forum or for the Questions forum? If the Questions forum, could it be moved to there? Sorry to sound like a newbie, but this is the first actual thread I started on here.
