Breakdown of an ANKEH disc tumbler lock

[mh]

A nice lock, probably from Taiwan or China, with a key that looks like a LaGard 2200 key, but a mechanism like an Abloy classic:



Here you can see the plug, the key, the locking bar and the housing:



Or, even more interesting, some spacers and discs removed:

Nice photos mh. Did you see my reply to your guess the lock? The key is like Lagard 2200 but the mechanism is not (as you point out). The mechanism is Abloy - yes - but taking the lock and key together the whole thing is very much like a Carl Kastner lock from the early 1900s. Lagard based their design on a fusion of this lock and the earlier S&G combination lock.

A further point, the webs or ribs between the bittings on the key don't really seem necessary for this lock.

mh, here's a picture (derived from one in my book) so you can see what I'm talking about. The Kastner lock was patented around 1918, about the same time as Abloy. The lock in the photo belongs to a friend of mine (which I had one!).

Thats acutally a really neat looking lock. Appreciate the interesting read

I believe so, but depending on the key code, they might be the only thing that prevents the user from pulling out the key at the wrong position.

Mh,

Pretty cool lock there. I see only 4 coded wafers in there with spacers. No false notches so it could possibly be an easy pick depending on the tension situation.

There's 7 I think. The other three are still in the shell.

Yep, looks like you are right greyman. I should have looked at all pictures more closely. The key really does resemble the LaGard 2200 key lock though.

I guess picking it would be kind of like opening one of those old Master combo padlocks - before they started putting notches on the discs. But how to tension this lock?

But how to tension this lock?

thats what i want to know...

[zeke79]

The center post that runs up and down the keyway. Simply a sleeve machined to fit tight around this post, then using simple "bind and turn" you could tension the pack.

[raimundo]

you may want to try some tool like a bit of rubber tubing to grip that center use a metal rod with an inch of tubing on pressed onto one end, the only thing that might be a problem with this, is that the rubber would negate any feel from the stem, so you will have to sense a proper set of the disc some other way.

[greyman]

Guys, have a look at the key: the first 3 cuts are 0-cuts, ie they hit the tabs on the discs as soon as the key turns. You can use any one of these to tension the pack since it's going to have to rotate to the maximum angle anyway. Thus an Abus type decoder/pick, suitably modified, ought to work.

I hope this makes sense.

I know we can do that on THIS lock greyman but others will not be coded the same so this will not always ring true. I was looking for a solution regardless of bitting. The abus lock decoder worked on the principal that all bottom disks were the same cut but that is getting way to advanced for the open forums now.

[mh]

And the Abus plus tool also works on the principle that there is no center post... Makes the tool somewhat more complicated, too.
