      I fear that as long as there are things not everybody has (money/power/fame/etc.), some portion of the population will turn to illegal, immoral, or socially unacceptable means to achieve their goals. Unless we really want to live in a society where equality is enforced and nobody is allowed to have anymore than anyone else, the presence of thieves and other criminals is something we will always need to deal with.

      Kryptonite today announced it will provide free product upgrades

      From what I have read, the upgrade will replace the lock core with one of a smaller diameter. This isn't really a long term fix - someone will probably discover a different brand of pen that will open the new locks as well.

      I have tried the Bic pen on my own Krypto lock - and it's really easy. The strange thing is, this isn't some design flaw with the lock. Everyone (hopefully) knows that all locks can be picked. But, it should be hard, requiring specialized tools and some skill. The Bic pen seems to have just the right magical combination of size, and balance of hard/soft plastic, that it makes an astonishingly effective lock pick. After opening my lock, the pen barrel had divots in it from the pins that looked just like my key. The plastic seems hard enough to push the pins down until they set, but then soft enough to hold the pin in that position.

      Also, this isn't exactly breaking news. [security.org]

        The pins in the lock are vunlerable to being raked because they're all set in roughly the same position. If they were disparate, you couldn't successfully rake them (except if you were very lucky and could bite chunks out of your bic pen to match the right key :)

    Interestingly enough, the problem was first reported in Britain in 1992. But it didn't go anywhere. Hurray for the age of fast information dissemination. And fast technology transfer to the bad guys.

    This is a flaw in the barrel style key system. I'm hardly a locksmith, but I've tried this on several of my locks and others just to prove the point, and the majority are not kryptonite locks. All of them have opened without more than 30 seconds of effort.

    The sick part is the problem has been well known to manufacturers since 1992, and nothing has been done about it.

    • The Kryptonite locks use the Ace or Ace II barrel, according to the forums I've been following. The former mechanism is somewhat easier to open using the pen exploit than the latter, but there are multiple reports of both types of mechanisms being opened. Same goes for the Kryptonite EV Disc lock.

      Further, even Kryptonite's (and other lock companys') New York models have been reported vulnerable to this attack.

      This is a flaw in the barrel style key system.

      No it isn't. It's a flaw in any cheap locks. You can open filling cabinets with a popsicle stick as well, and they aren't barrel locks.

      This is a problem with any lock.

      There are 2 things that a lock needs to prevent picking.

      1) A system that will prevent it from unlocking if any tumbler is pushed even slightly further than it should have been. If this isn't in-place, even a blank-key that fits the lock will open it.

      2) A system that prevents the tumblers from contacting with the locking mechanism. Otherwise, it's trivially easy to pick.

      And that's only to impliment basic security. I don't have any format training, but I can open 90+% of locks I see...

      Amazing as it may seem, quite a few safes don't follow rule #2. That means you can find the combination as fast as you could open it if you knew the combination. Also, it doesn't require any suspicious activity, as you just have a hand on the dial and a hand on the handle like you're someone that should be there...
      • Ya but it's more expensive to design a secure lock. I mean when I went sniffing about for house locks I could get most major brands like Kwikset at home depot for less than $50. This generally included a deadbolt and handle, sometimes more than one of each. Problem is they are quite easy to pick, as you note. You can literally use a paperclip and screwdriver, never mind if you have good tools, and you can get the keys copied anywhere.

    Tubular locks are usually designed so you have to turn it at least a quarter turn to open it, which would involve picking the lock several times. The Kryptonite they show releases the shackle in an intermediate position -- bad design there. A real tubular lock pick should open those locks; a simple plastic cylinder of the right diameter should not.
    • I've read this same exact post multiple times, and I still don't understand how having to turn it a quarter turn requires multiple picking. Any way to expand on this?
      • Here's an oversimlification: To turn the lock, the tumblers must be pushed just far enough to slide around a groove. Tumblers actually have a top and a bottom half, and turning the lock generates new pairs, each of which must be repicked. Thus these locks have the advantage of being very tedious to pick using conventional methods.

        They also have the advantage of being invulnerable to another popular method of defeating conventional locks: hammering in a flat-blade screwdriver and twisting like hell.

    While this is certainly something that lock manufacturers need to deal with, everyone needs to also keep one simple idea in mind.

    The purpose of a lock is to keep honest and semi-honest people from taking your stuff. If someone is damned and determined to take your bike, he's going to get it, regardless of what lock you use.

    I also have to nod in agreement with an earlier poster who pointed out that for the price of a fancy lock, you can get a bike that no one wants to steal. This is a perfect example of why my everyday driver car is an old beater that no one in their right mind would want to steal.

    European Union: The French and the Brits start bitching at eachother about which country has superior Bic pens. Germany and Spain wonder since when the damn Brits are part of Europe. The rest of Europe tried to talk tough before getting bitchslapped into submission by Germany and France.

    RIAA: Claim that people who open locks use it to fund terrorism. Randomly sue locksmiths.
    Microsoft: Vehemently deny existence of faulty locks. Release hotfix for existing locks, which consists of pouring glue in keyhole.
    SCO: Sue Bic, 3M, Canada, a random seagull and the tooth fairy for copyright infringement on their proprietary way of opening locks with ballpoints.

    Richard Stallman: Proudly proclaim the bike simply wanted to be free.
    Eric S Raymond: Something irrelevant that contains a plug for "The Cathedral and the Bazaar".
    Larry Wall: Make all locks so confusing that thieves don't know how to open them. Nor do the owners. Or manufacturers, for that matter.
    George Lucas: Make a movie about bikes being stolen with Bic pens. Milk this movie out until 2050.
    Bruce Willis: Get a bunch of oil drillers to find the thief and shove a nuke up his ass. And for the love of Eris, someone PLEASE screw Liv Tyler!

    It is easy to design locks, even tumbler-mechanism mechanical locks, that are unpickable by the standard manipulation techniques.

    It is even possible to build these 'unpickable' locks for a small multiple what a standard lock of the same mechanical quality would cost.

    You can make it difficult enough that burning or drilling the core, or taking a fire-ax to the door, is much more feasible than any manipulation technique. When the locking mechanism is no longer the weakest link, then it no longer makes sense to spend more on an improved lock.

Your contract is with the shop not the end manufacturer, so you are entitled to walk into wherever you purchased it and demand a replacement or your money back.

    I just leave a big hungry Rottweiler with an attitude problem tied to my bike. It's great because nobody will steal the bike, and when I need that extra boost going up the hills, I yell "Chopper, sic balls!" and point at someone up the street.

    When stationed at Kunsan AB korea, circa 1993, the only transportation option open to enlisted people was a bicycle. You could buy one at the base BX for about $100 bucks. For an additional $4.oo dollars, you could buy a chain with a built in combination lock. The biggest problem with the entire system was this.......EVERYONE had the same model bike, and the same chain/lock. You could literally spend a half hour trying to find the bike and chain that belonged to you. This was quite a problem for some of us, untill we learned that with a bit of tension on the lock, and a bit of manual dexterity, you could open any of the locks in about 45 seconds. After that, we all adopted the idea that those of us that had purchased a bike, but couldnt find it anymore, could just go ahead and ride what ever bike was handy. After all, EVERYONE had the same bike and lock, so really...........all bikes were secretly the one you bought. Therefore, if you were able to pick the lock, you were entitled to ride the bike. This Utopia breaks down when you consider that in most cities, not everyone buys the same bike and lock. Therefore, it is incumbent on the government to provide everyone with a bike, thus insuring that there is no need for anyone to steal a bike. I will be putting this idea to my senator soon.....hopefully everyone will have a new bicycle in time for the novemeber elections
