Master Lock 8118

[Jonathan1776]

This is my first post, so I hope this is the right forum to put this in.

For the past several months I have been honing my skills on normal pin tumbler door locks, padlocks, etc. I'm always trying to improve and try my hand at different brands and sizes of locks. The other day, however, I picked up a new and unusual lock at Lowe's that wasn't anything like my normal pin-tumbler locks. It is a Master Lock 8118 and you can see it here:

Basically, instead of a column of pins, it has a series of disks that all have to be rotated to an exact degree. It has no spring tension. The key is hard to describe... the teeth are basically like sideways dents of various angle/degree.

Anyways, I've researched this lock as best as I can and the only thing that I could come up with is that it seems similar to an Abus Plus lock and is sometimes referred to as a disk tumbler. However, other then that, I have yet to find any information on how to pick it and what kind of pick to use. I understand its internal workings, but since there is no spring tension, I have no idea how to approach it.

Does anyone have in information or helpful hints on this lock?

Any help would be appreciated. Thanks!

Well i'm not really familliar with the particular lock your talking about, but from your discription of disks, I thought maybe a warded lock?

But after searching on google, and finding this,

It looks like It might just be a tublar lock. But then I have no idea where you got disks from if it is indeed tublar.

A pic of the keyway and/or key would make it much easier.

From what you describe, it sounds like an Abloy-style disc lock. If that's the case it's definitely an advanced lock, and while there exist tools to open it the discussion of such tools is limited to the advanced forums

That didn't even occur to me. Good call though.

I'm gonna throw a "Keep Austin Weird" in here just since there are so many of us dominating this thread. >.>

Keep Austin bonafide.

That looks like a U-BAR bike lock, and I have no idea how to pick it. I guess you can stick around and increase your mad REP to get into advanced forums or keep looking byes

Thanks for the replies everyone. Hmm.. Abloy disc.. that may have been what I read instead of Abus. As far as being warded, I guess in a very, very loose way you might say it is, because the disks provide a type of lateral ward, but unlike a warded lock the wards move and if they are at all misaligned the lock won't open.

It isn't a tubular lock (in the technical sense) because the key is actually flat. It is double sided also.

The funny thing about this lock is that although I have no idea how to pick it, it doesn't "feel" like an advanced lock when you open it with the key. Internally it feels like something with high tolerances and almost even a shoddy construction.

I guess I'll have to wait 3 months and number of posts before I can take this issue to the advanced guys. I wonder if we can send an envoy?

Also, I'll try to find my digital camera and snap some pictures of the lock, the key, and the keyway.
