Kryptonite padlock

[Cman22]

Today i was at home depot looking for some padlocks that i could learn to pick. I found the master lock no. 40 and of course a kryptonite padlock. (The one i purchased is in this link) http://www.kryptonitelock.com/inetisscr ... em&pgrp=20
Being that i don't have one of those expensive tools for this type of lock i was wondering if one of you guys knows how to pick it without losing 70 buck. ANy tips would be appreciated.

Thanks,
Cman

there has been a big news story recently because someone found a way to pick them with a bic pen here's a movie of it http://thirdrate.com/misc/krypto.mov

yeah mate, I think the bic pen is your best bet

[TOWCH]

Bic pen trick does work on that lock if you can get it to fit. I own that lock and have done it myself.

It's not the bike lokc, its the padlock like in the link. I tried a bic pen but it was too small. Can you cut slits in it to make it fit and work? I guess ill work with it and display what i find out here.

i actually just finished a prototype tubular pick, made of a bic pen and 7 bobby pins for the feelers, my next pick is lathed, but i havn't drilled the end of it.

my friend has a similar lock, which i managed to open with my bic pen tubular pickworked just like a tubular pick would, may post pics of it later

If the pen barrel is too small, use the pen cap. It will probably fit just right. (Obviously you need to use a craft knife to cut off and trim down the shirt clip first.)

Hi. I've got a similar problem. An older ev disc lock where the barrel was a bit bigger. I tried the bic pen and cap thing and no luck.

I spoke to one lock smith who was too busy.. said go to home depot and buy a drill. Where exactly would you drill it? in the little slot on the key hole?

or are there any other suggestions?

Thanks

Hi JC (and the picking part applies to Cman too),

I'm just wondering why you'd want to drill a disk lock? I presume we're talking about a tubular motorcycle brake disk lock and if we are, I presume you realise that if you do drill the thing it's then rendered completely useless to you? So if the lock is on your bike and you need it removed, call a locksmith who wants to make some money (too busy? the guy was obviously a clown - as for suggesting you drill it, I'd hate to try drilling a tubular without an appropriate drill bit. Perhaps he just didn't own one and didn't want to look like an amateur). If the lock isn't on your bike and you just want to learn about it, drilling it will break it. You can pick the lock (with some practice) using a customised tension wrench and yes, something as simple as a paperclip. This is how;

- Create a tension wrench which you can insert into the little slot in the inside portion of the lock and which will enable you to rotate the plug without disturbing or reducing access to the pins. A ground down allen key can work quite nicely.

- Insert your newly created wrench and apply a slight force in the direction the lock opens (almost certainly clockwise).

- Using your paperclip (or anything that will enable you to push the pins down) push the pins down one at a time and you'll find one pin that seems to be a little harder to push than the others.

- When you've found that pin, push it until you feel the pin set. You might feel a slight click and at this point the plug should rotate (very very minimally) and you can proceed to find the next pin that is the hardest to push down. Be careful though that you don't overset the pin which will happen if you're pushing too hard and applying too much force on your tension wrench - a light touch is the key (pun intended).

- Eventually you'll have set every pin at the shearline and the plug will rotate until the top pins make it to the next set of bottom pins. (ie if you have a 7 pin lock the plug will rotate approx 1/7 of 360 degrees). At this point, each of the pins will unset and you'll have to repeat the whole process over again.

- Wash, rinse and repeat until the lock opens. With most tubular locks you won't need to rotate the full 360 degrees (so you won't need to pick the thing seven times) but perhaps 90 degrees before it unlocks. This means you'll need to pick every pin probably 4 times.

Either that or get yourself a tubular lockpick. They really aren't very satisfying for the hobbyist but if you need to get a lock off and a locksmith wants to charge more than $70 it's not a bad investment. For even the least talented lockpicker it makes picking simple tubular locks (which most of those disk brake locks are) about as simple as opening them with a key. I bought one thinking it might be fun to play with but it's really very boring (insert, jiggle and remove slowly to unlock) I honestly prefer the pin by pin method but obviously it's a lot more challenging.

can anyone explain why the "pen trick" actually works? is it true that vending machines and telephones are vulnerable to it?

id be interested in seeing your tubular lock pick

[UWSDWF]

yes, no and look at the pictures on a lockpick selling site.... remember stealing from vending machines will get you jail time

[mercurial]

Alias described the process of picking a tubular lock with a simple tension tool and a probe(in this case a paper clip) very clearly above.

For those who have not tried this technique before, it is worth noting that with some tubular locks, the notch which allows insertion and removal of the key at the correct point can be large enough for the pins to pass through.

When turning the plug, take care to avoid this, lest you may find pins and springs flying towards you.

This phenomenon is somewhat analogous to the driver pins dropping into the bottom of the keyway in a conventional pin tumbler lock, when the plug is turned 180degrees without the key - but with a conventional pin tumbler lock the driver pins cannot escape, they merely have to be lifted out of the way to free the plug.

About the 'yes' - it's a mixture of self-impressioning and jiggling. Look around here, I believe it has been described before.
