Can a Masterlock 3UP be picked?

[eurolock fan]

Hello I have a Masterlock 3up padlock and cannot pick it for some reason. Also the core is loose and partially sticks out the bottom of the lock. I don't even know if the lock even works as it came without a key. Does anyone on here have experience with this type of lock.

every lock can be picked, unless of course it cant!?!

i would use graphite powder (spray it in the lock to lube it up)
i dont have experience with this lock, but it seemed to work with my friends, which is similar to what you described.

is this a new lock, or a lock thats been sitting around since WWII?

I've tried graphite powder. The lock is brand new but I think it might be defective because the core sticks out of the bottom of the lock and its loose.

the 3UP is a " user keyable" lock.. you put the key you want in the lock and hammer it in with a special tool .... it breaks the pins off at the correct legnth and the key will now work .. Great for keying alike many padlocks... when it is "set " the core is flat like any other master padlock, when it is in the new unused state the core sticks out of the bottom ..



You have a lock that is not keyed up so it will not pick.

I checked the master web site .. sorry not much info on the " UP" series so I guess you will just have to take my word for it

Not sure if you're doing this or not but when you lubricate the lock go ahead and rake it 15-20 times, without tension, and to really get the lubricant spread out and worked in.

like keysman said, if it hasn't been "pinned" it won't pick. If it has been "pinned" it will still be more difficult than a regular master padlock because the way the pins are designed with break points leaves you with heavily serrated/spooled tops and bottoms.

Well that explains it. Thanks. Just out of curiousity does anyone know where I can get the special tool at?

Didn't sound like you need a special tool. Just a key with the appropriate warding and a hammer. Probably want to make sure that when you hit it, you keep your fingers clear of the key . If you can, hold it in a vice while striking it. Sounds like an interesting lock. I also imagine that it would be somewhat difficult since the plug sounds like it would not only shear left or right like you would expect, but it sounds like the plug would also slide in and out at least to some degree. So, it would also shear in and out as you apply pressure. Do you have a means of posting pics? Sounds like a pretty interesting lock. Is it like a user keyable master number 3? I would think so from the name.

you do need a special tool for "pinning" it. You have to hammer fairly hard and you wouldn't want to do it on the key. The tool is available through locksmith distributors. It's nothing special, just a large punch with a slot in the middle so you are punching on both sides of the key.

These locks are neat and interesting but they suck. They generally never work smoothly and it's just an idea that should have stayed on the drawing board.

once these are pinned, they are more difficult to pick than regulare, non-serrated #3s, but they are definitely doable once you get a feel for them.
