whats the deal with kryptonite bike locks?

[Tempature]

im sure everyones heard about the "bic pen opening kryptonite bike locks"

but is it true?

ive seen videos, how is it done?

[linty]

apparently they've changed their design (diameter, most likely) so it doesn't work anymore, but basically the pen works the same way as a tubular lock pick, which is more like impressioning than standard picking really. the turning motion when you wiggle the pen binds the pins, they dig into the pen, and eventually when they have dug in enough that the shear line is clear, the lock will open.

in general undersized tubular locks are almost always terribly made.

I think they have Rotatating disk mechanisms, Abus granit, or abloy style.

The Bic pen wont work on everyone jsut pretty evenly combinated locks, what i want to know is, what arm chair genious descided to shove a bic pen into there bike lock to start this?

[Tempature]

lol good question!

[Eyes_Only]

LockNewbie is right, I think they switched it over to the disk lock style. I think they're all like that now since I cant seem to find anymore tubular locks for sale from them, or maybe I'm not looking hard enough.

They had a trade-in program where they would replace the bogus locks with new "better" ones. The program ran about a year and then they ended it. That's really standing behind your product. I missed it by a couple of months and they wouldn't hear anything about extending the program.

I find that blue pens work best.

Actually it IS TRUE! lol A while back a buddy of mine in NY was complaining about someone locking one of those Krypto NYC Fuggetaboutit lock and chains on his gate, which had been there for months and never taken off... so after coming back from the bars, I spied and we all placed bets on if I could do it... grabbed a bic, and a leather glove... push-twist-push-twist-POP! It opened and it was like winning the super bowl we were all jumping around laughing and in shock! I took out the bic pen and it had indeed impressioned the pins in the lock perfectly! I still have the chain, tossed the POS lock. I tried it again with an older krypo-U-lock I have before I switched and it worked again.... It's just basic impressioning... I still see these types of locks around today, it's pretty scary to see $1000's bikes on a lock with a HUGE overlooked exploit...

The newer locks use an M-cylinder based off abloy's disc system. I have not see anyone do a profile on such a lock, but I would be interested to see a break down of how they work... anyhow good day.

bicking was big news in sept 04, but it has died down to where its seldom mentioned, it does work in warm climate best. plastic loses some of its impressioning qualites as the temp lowers, Once, this was bigger than bumpin on the lp101, but relatively quickly, it calmed down. pushin with a little bit of binding twist to hold the pin while it makes the impression then repeat repeat, pete pete
