Krptonite Abloy-Style Lock Extracted

[dougfarre]

Well after many hours of dremmeling, hammering, cutting, drilling and crying (what?) I have extracted the little baby disc lock hidden away in the depths of a kryptonite U-Lock. I used this lock because I had a lockout call and was forced to cut through the U, but the lock is still functional so therefore in perfect condition for manipulation on my own time.

I wanted to isolate the the actual lock, so i could make a cutaway eventually. But here is what i had to go through to get this little lock out.













Sorry about the image quality.

props for te effort. but was there any reason you coudlnt just pick it (or try to) while it was in the rest of the lock?

[dougfarre]

Good question.. I guess by isolating it down into a smaller little lock its not so scary anymore? Also, i mentioned above that i wanted to make a cutaway because I am having trouble understanding how these locks work. This is the closest thing to an abloy i can find without buying a new lock.

I was thinking of buying this lock too and practice on it incase I ever get called out on a lockout job for it. Don't really want to bring out my grinder and expect the customer to pay me for something his backyard mechanic neighbor could have done for him for next to nothing.

I wouldn't mind seeing the discs in them. see if theres any false cuts.

I'd doubt the company went that far to improve their product. Even if there are false grooves, cuts or whatever it'll probably offer only marginal security against a experienced and skilled picker.

What shape the keyway has?

[copeman]

master also makes a u lock like the one shown and is much easier to extract the cylinder if anybody plans on following in his foot steps

Actually, I was trying to bring this up in the KWICKSET SAFEKEY thread (viewtopic.php?t=25767) by Hinting about extreme Macs on the kryptonite ulocks (page 3). And jaako you shot me down cause you misunderstood me. Really, I was trying to explain a bypass method without giving away to much information.

I'm not going to give away to method, but I am going to tell you that it works, and why it worked, and why it doesn't work anymore because kryptonite made improvements to their Locks!

When kryptonite first came out with their abloy style ulocks, I am assuming they specified their own Maximum Adjacent Cut Specification on their locks to not be able to deviate from cut to cut more than a difference of 2. For example, a lock with be coded like:
024531-> see how the adjacent cuts never deviate more than 2 cuts?

This allowed for a very special type of bypass method that was extremely simple!!!! (Im not going to say how)


Now. More recently, kryptonite realized this, and respecified their MACs to be more extreme and this solved this problem altogether.

[JackNco]

there are no macs on abloy style locks. or any other lock where you turn in to the mechanism, so lever locks and safe disc locks (Cant remember the name of them) that use a key. Im sure kryptonite were aware of this when they first produced the lock.

Dude this sucks! I just came back from Lowes, Home Depot and Sears and they were all out of the Abloy style bicycle cable locks. Where else can you find this thing?

Should have bought one when I first saw it months ago.

As if you need another reason to move to Sweden?

[dougfarre]

Dude, its not on the cable locks, its on the U-LOCKS

[Eyes_Only]

Ok its even worse then cos I saw no U-locks anywhere either.

You have to goto a bike shop.
