I just Picked a master lock no.140

[pick kidd 101]

i have a fairly new master140 with a long shackle and i use a needle pick(straight pick similar to peterson knife) to slide the levers at the back of the lock(past the pins in the plug). heres how i do it
i apply outward tension on the shackle
insert the pick in the key hole, no tension wrench needed here
and rock or slide the first lever away from the center of the lock, the shackle will pull out slightly and you will feel the lever lock into place much like a pin catches the sheer line. then i simply feel for the second lever on the opposite side and slide it in the opposite direction, the shackle simply pulls out. no "picking necessary"...although i have picked this lock many MANY times before i discovered it bypass weakness, hope this helps.

I've got about a dozen of these 140's (they are all over the place at work) and what I found was that the first pin was giving me a false set every time I slide the pick in because all of my tension wrenchs did not allow sufficient room (primarily because the bottom pin is so long). I eventually got creative and made a 2 prong tension wrench which would allow adequate clearance for any of my picks. It works like a charm and I can pick any of these 140's in seconds with just about every pick I own although the half diamond seems to work the best.[/img]

I'm not completly new to this hobby, however I am a noob!
A friend gave me a 140 last week. I got on here a decided to see if I could find any info on it, and sure enough this little lock is pretty common.
I was having the hardest time trying to get this thing open. So within a few min. I just put it aside, and continued on with my Kwickset deadbolt.
Well just today, I decided to give the 140 another shot...this time with a half diamond that I made last night. BINGO!!! She opened up like a virgin:)
I've since opened her up 5x today. I only have two picks to use, and both seem to work on anything that I try. Standard 4-5 pin tumblers anyway.

Here are the pins out of a Master 140. As you can see 3 spools and 1 serrated driver, normal key pins.

PS. Look at the wear on the bottom pins from years of picking!!!!!

What do spools do?

Hello, Im new to lockpicking. I was able to open a 140 a few times, but now it seems to be stuck: I hear 4 clicks, but it doesn't open. What am I doing wrong?

To answer my own question: instead of just poking around, I really concentrated on each pin. Applying just a little pressure (thanks to tips earlier in this thread), I was able to pick the lock within 2 minutes! What a great feeling!
In my case, pin number 2 is the key. After that, a piece of cake.

I have a master 140 and am able to open it pretty much 100% of the time after i get it to false set. Getting it to false set is a different story. SPP i can get it to false set probly 1 in 20 tries and i know where the security pin is and know the relative heights of the pins. I find it to be one of my hardest locks despite the single security pin.

I have a similar looking 5 pin brinks 40 mm lock that has 4 security pins and can pretty much SPP every try. Go figure.

Cheers.
