For what it's worth, I tried this at home with two different U-locks
(neither one Kryptonite brands), and couldn't get it to work with either
one. Both of these locks take different diameter keys, neither of which
fit any of my pens very well, so this may have made a difference. I *have*
managed to pick cheap padlocks before, using a screwdriver and paper clip.

That's not to say a different diameter plastic tube won't work.
I too found it hard to believe, however with a bit of persistence, I
managed to open the NYC U-Lock sold by MEC.
Jamming the pen barrel in hard enough causes it to flare and fit.
After that it's just twist and jiggle.
It took less than fifteen seconds the third time. Sad.
I've not yet gotten it to work on the Bikeguard5 sold by Norco though
I predict that I will before day's end. I don't have a key for it
anyway.
I was thinking of the havoc one could cause at a bike rack by just
switching around peoples' locks.

What do you think the 'mechanism' is that is allowing it to work. You think
it's fitting over the post part and covering the indents, thus letting it
slide off?

That's one of the locks I tried. So either I wasn't persistent enough, my
pen wasn't suitable, or I'm just no dang good at it.

I think it's the same principle as picking a regular lock: torque is
applied to the barrel, and if the pins are jiggled back and forth,
whichever one is bearing most of the force will snap into place, allowing
the barrel to turn slightly more. If you continue in this manner,
eventually all the pins will fall into the correct positions and the lock
will open. This approach can be defeated by devices such as
mushroom-shaped pins (in a regular lock), which will fall into the wrong
positions.

There is a post (#332), in the bikeforums.com thread that Jym linked,
explaining how it works.
"The lock works by having a series of pins arranged in a circle
parallel to one another. Each pin has a spring behind it, and a notch
cut at some height into it. The key works by depressing each pin
exactly the right amount so that the notches line up with the collar
that is preventing the lock core from turning.
Now, why the pen works: it's the plastic and the springs. The plastic
is obviously hard enough to push against the springs, but soft enough
to deform under their pressure. Either the pins bottom out in the open
position (in which case it's just a matter of mashing the pen in hard
enough to bottom the deepest pin, and it gets mangled as the others
bottom out), or that's why the wigglin' and shakin' (you're vibrating
the pins into position, and the pen then holds them there). So, in
addition to different diameters not working, something made of a hard
plastic (like the hex-crosssection Papermate pens) probably won't
work. And something really soft (like silly putty) shouldn't work,
either."
There are also numerous posts and videos confirming the findings on
various different locks having cylindrical keys. Apparently his hack
has been known since at least 1992.

This pen was one of those no-name freebies.
It's got a thinner wall diameter than the brand name Bic.
I used it because it flared more easily.
I still haven't defeated the cheaper Norco lock.

It may not have helped that I was turning in the wrong direction... I'll
give it a try again later.

There's another post on the topic (#334) referring to two different
types of that cylinder used by Kryptonite. Perhaps these off-brand
locks which don't open have similar characteristics - either through
design or co incidently by having wider tolerances in quality control.
"A locksmith acquaintance told me that there are two different types
of lock cylinders in Krypto Barrel locks:
ACE standard--all seven pins have the same tension; and
ACE II better--different spring tensions on all 7 pins.
He thought the ACE II locks couldn't be picked this way. I put it out
to the list to try both and report back. Brian is also going to try
the Bic pen technique on the locks in his shop (I'll report his
findings back to this list). The ACE is stamped on the center part of
the lock face."

I just successfully picked a MEC NYC lock, and then a PlanetBike "extra
guard" lock. It was easy once I got an appropriate pen, and turned it in
the proper direction.

I'm sure that at worst, this would make it more difficult. I'd like to try
one, though.

Is this the lock you just picked (I did not see the a "NYC lock" in MEC)
I just bought this lock yesterday from MEC in Vancouver.....I may return
it if this is the case
Quoted message said:Is this the lock you just picked (I did not see the a "NYC lock" in MEC)
No, that's not one of the ones that I picked, although I would be somewhat
surprised if it didn't work on this one as well. MEC no longer appears to
carry the NYC lock that I have.
That's a fairly pricey lock, so I'd definitely consider returning it just
in case, or at least trying the pen trick yourself.

Thanks for the reply, I will try to pick this lock tonight.
One last question on the NYC lock. Now that I think of it, when I was
shopping at MEC Vancouver, I seen a very heavy chain link lock encased
in black sheathing. Is the NYC lock that you are referring to? I did
notice that this particular lock it is not on the MEC website
Regards,
Mark

No, this is a heavy-duty U-lock. They haven't had them in the Vancouver
MEC for a while now.

The website I looked at warned that it might possibly make the lock

Those of you who tried this - do your keys still work?

But you can't unlock it with a pen and then re lock it with the key.

.... unless you file the little metal nub off one of your keys. The key
will then still work, it will just become possible to insert it the wrong
way.
