Help with Master 930

[x8xViperx6x]

Ok, im getting alot better/consistant on picking all the locks I have, so I decided to step it up. My friend gave me this lock he found it in a parking lot about a year ago, and i been working on it for a few days and ive had no luck.. Anyone have any tips to pick the #930

It is a five pin lock with security pins. For mine, i use a tension wrench for top keyway tension. The end has to be a little bit longer than usual to reach down into the first pin. Then a SO medium short hook work fine. The regular pins set very easy with light tension, but there are spool pins. For mine, after the second spool pin it is open, but theres one thing to know. You may have picked the lock open and you don't even know it because once its picked using light tension, it takes heavy tension to turn the plug because it has a fairly strong spring. So if you think you have set all the pins, give the wrench a more than average amount of tension and see if the plug turn. The shackle is not spring loaded and it will drop open once the plug is turned all the way. It also uses ball bearings to resist shimming. Hope it helps.

The 930 is a 5 pin lock with 4 spools, I usually get two or three false sets before popping it open. The biggest trouble I had with this lock, as apb touched on, was figuring out the best way to apply tension. If you have a tool that'll fit then top tension is probably the best bet, but I've also had a lot of luck with using a wider/thicker tension tool than normal in the bottom of the keyway. This keeps it from slipping under the ward and lets it apply the correct tension. If you're not getting a false set pretty quickly, or it feels the pins are all moving pretty freely without setting, it probably means the right tension isn't getting applied. That's the part I had the most trouble with anyway. Good luck!

Success! Thank you guys for the info, you helped alot. What I ended up doing was using two tention wrenches on the bottom (one facing another) and it worked out for me. I had no idea the shackle had no spring so i turned the plug and nothing, so I was confused for a sec, then pulled. Any going to attempt again. Thanks for the help guys!

Good thing that using two tesion wrenches work for you.i just got one of those 930 master lock and use one tension wreched and shork hook used light tension The regular pins set very easy with light tension, but there are spool pins.did not take that long to open the lock.but is true what (apb)said You may have picked the lock open and you don't even know it because once its picked using light tension, it takes heavy tension to turn the plug. other than that you should not have any problem picking this lock Hope this helps.
