    Kryptonite U-Lock Woes

    I purchased a beefy black and yellow NYC Kryptonite U-Lock--- whatever it was before they renamed it. I have had it just over one year, and the spring mechanism is broken inside making it very difficult to unlock. Anyone else ever have a similar problem? Any suggestions for taking it apart to fix it? I was hoping this would be the last lock I would ever purchase...

    You could lube the lock. There is a whole debate about unfreezing locks in cars, but I'd just try WD40. If it frees it up, you could follow it with some triflow.

    Call Kryptonite and see if they will replace it.

    I've had three OnGuard locks that have frozen up on me. It's no fun when you're standing on the sidewalk trying to open your broken lock.

    Filtersweep - We're sorry you are having a problem with your Kryptonite lock! That lock has a lifetime warranty so if you think something is broken with it, please contact us directly. Since you are in Norway, please do email our customer service and they will help you out. Customer service is at letters@irco.com

    If you think it is just a little 'sticky' you may want to try either spraying or dripping a lubricant found in any bike shop into the locking mechanism. It is important that the ingredients of the lube include either silicone, graphite, teflon or parafin.

    Hope that helps and again, sorry for the trouble!

    Just so you know, it probably won't be the last lock you'll every own. I have had numerous bike stores and mechanics in Europe tell me that Kryptonite is the easiest U lock to break open. There was a test done in Sweden on numerous U locks, and Kryp. was the easiest to get into. This was up to 8 years ago so I don't get why people still think they're so great. Not to mention the fact that they (and other makers of U locks) can't seem to come up with a decent attachment system when it's not in use. I have to always use velcro to keep it in the holder.

    Do you have a URL on the tests you talk about? I recently found out about the Kryptonite Ulock and the bic-pen issue. I own 2 U-locks by Kryptonite. Loved my first K-lock so much back then I bought another when I got a new bike and got another for a backup. Yah you counted 3 K-locks there but I lent one to a friend of mine and he was goofing off on a ferry ride and dropped my K-lock into the water.

    Anyways, how does one do this K-lock replacement thing I've heard of? Can Donna of Kryponite explain more of what I need to do? My local LBS just said I need to talk with Kryptonite. My locks are the (off the top of my head) around 10-14yrs old. I own the Evolution 2000 and I think a 4.0 (I'll have to check on that). Both bought at my local LBS tho I can only find one of my reciepts and that's for the Evolution 2000 lock when I ordered my new bike. My LBS can't call up reciepts that far back.

    Any modern heavy-duty U-lock of one of the big manufacturers (Abus, Kryptonite, OnGuard) will provide about as much safety as possible - for a U-lock. But if the thief has time, tools and determination, your bike is his no matter which lock you choose. All locks can be broken or bypassed.

    We have several threads here about how you also have to think where you lock your bike and how you use your lock(s) - some even call it "locking strategy". Search that and you will have lots of info.

    Well perhaps I should have mentioned I'm looking for a U-lock (I'm still stuck on Kryptonite locks somewhat) that takes the longest to defeat.

    I tried to do that bic pen thing to my 8 year old Kryp and absolutely could not get it to unlock. Has anyone here been able to do that?

    just because you can't doesn't mean a thief can't either. I'd say it's safe to assume if you really knew how to do it, it could be popped in seconds (don't mean to be rude there). I replaced $50 in locks when I heard about the bic pen thing.

    here's a good listing of lock ratings http://www.soldsecure.com/Leisure.htm

    anything gold should be adequate. I just grabbed the Onguard Brute STD 5001 for $40 on amazon, cheapest gold rated lock I could find. It seems like anything rated gold typially sells for $80+. This thing is beefy as hell, I'd definetely recommend it.

    The owner of one of my LBS told me the bic pen thing only worked on 1 in 10 U-Locks in a test. Plus I've personally never heard of it happening, just heard the stories about the possibility from everyone. Nice thing about the new U-Locks is the straight keys, so no bic pen worries anymore.

    That's kind of what I thought- the bic pen thing only works on the cylinder-shaped key locks?
    ...and don't forget to stretch!

    Yep. Some locks were much easier to open than others, but I managed to open my New York Lock, 2 Magnum (aka on guard) U locks, and 2 magnum Disc locks, and a plethora of no name u locks.

    The New York lock was by far the hardest to open. The On Guard/Magnums opened as easily as if I was using the key.

    Out of all the lock companies that made these locks, Kryptonite was the only one to front up with a replacement program. My New York lock was 10 years old, and was replaced by a current model free of charge. Magnum didn't even reply to questions and took the opportunity to re brand their company so they could then proclaim that no On Guard locks use tubular keys. People who had purchased Master Locks also got silence. Even a turn in your old lock for a discount program would have gone some way towards restoring my trust in their brands. I would have been overjoyed to have such a deal on my old lock, but Kryptonite replaced it outright.

    The lock industry relies on security through obscurity, and will happily take a lot of your money to give you the feeling of security while knowing full well the flaws in their product. Look up 'bump keying' if you want to have your faith in the lock industry shaken.

    The current Kryptonite New York u-locks are as tough as anything on the market. I will never buy another brand. Kryptonite stand behind their products.

    the owner of that LBS lied...of all the ulocks in question, once you figure how-to with a Bic-pen, they all become easy...someone had a video posted on BF sometime back (2 years???) that showed a guy open multiple ulocks in a row...so it's not 1-in-10 unless the person didn't practice.
    You know you're getting old when you look at a beautiful 19-year-old girl and you find yourself thinking, "Gee, I wonder what her mother looks like?"

    I have bic'ed two U-locks, which is as many as I ever tried to... That lock is easy prey.

    I had the same problem, about every three months you need to take it apart and lube it. DW-40 works well, or T9.

    That's a company that cares about customer satisfaction. Of course we already knew that.

    I've had my Kryptonite Evolution replaced under the return scheme & I'll be buying a NY u-lock to protect my new bike. I also recommend them to my friends, family and anyone who asks.
