 Fort Knox with a big flaw Sep 04, 2011
By bdgilfry@wildchildpublishing.com

This thing is a tank, weighing in at around two pound ten ounces including the mount, and is big enough to secure my bike to trees -- which are only slightly more prevalent in Los Angeles than well-constructed bike racks. I like the way the mount attached to my bike (although, because of the size of this lock, I found mounting locations limited) and how easily it operates (when it operates properly).
In my experience, most of the problems that reviewers here have described about the key sticking probably stem from not inserting the key to the bottom of the shaft before trying to turn it (at least, that is the official word from Kryptolok).
HOWEVER, last week, I had ridden to the store to do a little shopping and found that this behemoth was locked... as in, I was locked OUT. As I had begun to rely heavily on this lock, I had left my cable lock at home. So, the choice was, one, don't shop, but return home for the other lock, or two, shop without securing my bike. Since this was a Trader Joe's in West LA, I did the latter, and thankfully, with no ill repercussions.
When I got home after shopping, I found that this lock was still "locked out". The key would not turn past halfway (and yes, I was being very careful to insert the key fully before attempting to twist it). Finally, in frustration -- and knowing how well this technique has worked in other instances throughout history -- I dropped the lock onto the ground from about three feet up.
Voila! The key turned. I shot in a little WD-40, and the lock has worked well since.
Now, after having read and considered the similar problems reported here by other reviewers, and having experienced a similar situation myself, I have to decide if returning this lock would be the best option... or, do I keep it, hoping that the one incident of failure was a fluke?
What would you do?
*Edit*
I decided to return it.

 Great Lock! Sep 10, 2010
By JeffM
I purchased this lock for my daughter to take to college. Her school's campus is notorious as a magnet for bike thieves with lots of bikes stolen each year. She has a cruiser/hybrid style bike with large rims/tires and the frame is a bit larger than typical road bikes. The extra
width and length of this lock easily allows it to go around the rear tire/rim/frame AND the bike rack which completely locks the frame and rear wheel to the rack and in her case doesn't leave a lot of extra room where a jack or pry-bar could fit in and try and break it,,a standard size U-lock may better suit your needs as you don't want a lot of space left over after locking the bike to a rack. She uses just this setup when she's at her classes during the day but at night back at the dorm she adds a second STD U-lock to lock the front tire to the frame(since she has quick release rims) and the next day she just leaves that U-Lock locked to the bike rack until she returns. School's only been in session for 3 weeks now and she said her dorm is posting notices already about missing bikes and to use "Good" U-Locks instead of just cables as they've already had quite a few bikes stolen that were locked with only cables or inferior U-Locks that are easily cut or pried open. Kryptonite U-locks are becoming the lock to have at her campus, they've got a great following. Final note about bike security...we also used a small cable to lock her seat to the frame, i'm sure it'll be easy to cut but may help keep the opportunist thief from quick releasing the seat and taking it.
I know it may be overkill but a couple extra dollars spent now on good security makes us feel better and hopefully makes her bike a less attractive theft next to the dozens of others on the racks that are not as secure.

 Just another happy pedestrian. Nov 04, 2010
By Grrreat
This lock is great if you don't want your bike to go anywhere, with a rock solid and durable exterior. However, if like me, you like to ride your bike, this may not be a good choice. The locking mechanism started sticking after about 6 uses and is now frozen completely. My keys are bent and my bike is stuck on campus until I can figure out how to break the lock or borrow a grinder. All in all, I'd say it's doing a great job at keeping a thief with keys like me out.

Lock broken, but protection guarantee seems to work Oct 01, 2010
By G. Russell
The lock was broken and my $900 bike was stolen 2 days after securing it with this lock. The protection guarantee seems to work, though - I'm filing the paperwork and they haven't given me any trouble thus far, so I should get $900 from Kryptonite for the stolen bike.
Lesson? Get a stronger lock if you have a flashy or expensive bike. I hear good things about their New York series.

I worked great until it got defeated Oct 13, 2011
By Tekon
I had the grey Kryptonite for a while. And it worked great, until one night. I came to get my bicycle off from the parking meter and all I found was a twisted "U" part of the U-lock, and the key cylinder laying on the ground... it was so surreal. I just left them there. Later on after getting my composure, I found out that the locking mechanism was broken as well.
This theft was carried away no more than 30ft away from me between 7-10pm.
In conclusion... I think they must've used some sort of leveraging tool. I've seen a guy with a long steel pipe up his sleeve. maybe 4foot long. It seemed as if it was done effortlessly.
Hence I would advise anyone that care about security to not bother with this lock. Since it only locks on one side, if enough force is applied, one side can slip out.
After this incidence, I've done some research and found that: OnGuard has cheaper locks that locks on both sides of the "U" part, and Kryptonite offer that for their Evo(Orange), and NewYork (Yellow) locks. But if you want maximum security and don't mind the weight and hassle (it takes more time to lock & unlock) then go with a chain lock. *Cables are useless.
