Lock with a keyhole from hell?

[talbuz]

I've just come across a type of padlock in the hardware store that is new to me. The blade of the key, if seen in a silhouette, would appear as just a strip i.e. there are no protrusions in its profile as with a normal pin tumbler key. The working parts are not notches, but squarish bevels at different at different angles on one edge of the blade. As I said, this is bevelling is only within the thickness of the blade.

What intrigued me was the keyhole, a perfectly circular opening concave opening. I dont yet have one of these locks in my hands but clearly a tension wrench cannot be used as with the locks Im familiar with.

Maybe this is a well known mechanism, but I've been away from lock-picking for a while so Im updating myself now on the latest technology! Can anyone tell me what this lock is called so I can read up on how it works and how its picked etc. Thanks.

Sounds like a disc detainer lock. There's a recent thread here about Kryptonite locks that has a key pics in it for comparison.

Thanks Steve I'll check it out.

Meantime, sorry I seem to have somehow double posted!

Yup, probably on of the asian imports, disc detainer, or also called abloy-type although you only call it an abloy if it says abloy on it.

I was off to buy one of these locks, and saw one in a cheap 'Pound' store, so got that one. Here it is:

Its interesting that these locks dont have a spring loaded cylinder. So does tension wrenching come into the process of picking at all?

If this is an Abloy clone, then its one of the hard or near-impossible to pick locks I read so much about?

Raimundo and Legion303 got it right, but I thought I'd give you a couple links to go to anyway:

Picking Abus and Abloy type locks seems to be reserved for the advanced forum and seeing as I've never had one of them in my possession there isn't much more that I can help you with.

Cheers thanks.

Im getting the idea now of what these locks call for in the way of NDE, though cutaway sections are hard to find. Quite an interesting design of lock.

I bought a lock like this on a street market, it was something like 5 or 6 euro.
My idea was to pick it so I put it on my toys bin waiting its turn. Maybe in a few weeks...

If I remember correctly my key cuts look exactly like yours! I hope I'm wrong, this we I'll post a picture of mine.

Cheers

i bought a disc lock from an asian/hispanic grocery store a few months ago for 2.99$

i might file one of the keys down to try and pick each disc one at a time.. i'll see if thats even possible

[femurat]

I was wrong: the keys are cut different, even if they look similar.
Fortunately you can't open all this cheap padlocks with the same key... at least not with the original key

talbuz, I'm sure it isn't the best example on the site but I did take a disk detainer mechanism apart a while ago and posted some pics at the end of this thread.

Sorry to bring up a semi old thread but I recently acquired one of these locks and was wondering if anyone knew how to disassemble them? I know picking the disc-detainer mechanism is reserved for the advanced forums but I don't think take downs are. Thanks in advance!

it is possible to pick each disc,one at a time, but i dont think filing the key would work.
here is a link to me picking a similar lock.

Most have a screw that can be accessed when the lock is unlocked. For an Abloy, on the side of the lock the shackle opens on, a small hole allows an allen wrench to go into the lock and take out a retaining screw. The cylinder can then be removed once the big faceplate in the front is taken off (also screwed in, held in place by the first retaining screw).

My lock is a really cheap knock off of a disc detainer but it appears to be the same as the one mentioned above with the pictures. I could provide pictures if need be but the lock is quite bland. There are 2 holes on the bottom where the shackle shaft meets the base of the padlock both of those appear to be only for drainage though. There is nothing under the shackle either, the only thing I can think of is to pry the ring off the is in front of the disks (see pic of keyway in the upper part of this thread). Thanks for the help dg.
