Key Space and Depth Information

[mcm757207]

I've noticed there is no good, single source for key spacing and depth information on the internet. At least if there is, I haven't found it.

So I said, why not make one myself? Here is the link: Spacing and Depth Information.

So far I don't have as many as I'd like; it's certainly a work in progress. Here is a list as of my last update, click the type of lock to be taken directly to it:
Corbin Russwin Z and DH Class - System 70, Corbin Emhart High Security - Z and DH Class, System 70, Corbin Z Class - Pre-System 70, Russwin DH Class - Pre-System 70, Corbin X Class - System 70, Corbin X Class - Pre-System 70, Russwin N Class - System 70, Russwin N Class - Pre-System 70, Russwin 981 Class, Old Russwin 852 Class, Old Russwin A Class, Old Russwin 752, Chicago Tubular, Fort Tubular, American Lock Tubular (New), American Lock Tubular (Old), Greenwald Tubular, Assa V-10 High Security, Sargent, Medeco Biaxial/M3, Yale KeyMark, Arrow, Dexter, Falcon (Not IC), Ilco, Kwikset (Standard), Kwikset (Titan)

While I think this will be beneficial to locksmiths, I would also really like to make it a resource for hobbyists. So if anyone has any cool or obscure locks that you have space and depth information for (or better yet, measure them yourself!) please PM me. It's OK if it's only partial. Also, if you see any errors on my part or suggestions please let me know. Finally, I would like to note that, according to the US Copyright Office, "Copyright does not protect facts, ideas, systems, or methods of operation" - so I think I'm good there.

Enjoy!

Awesome listing man, but I have an issue with one of them.. since when did Medeco Keymark become Yale Keymark??? and why is this the first time ever I'm seeing Yale and Keymark in the same sentence? Did parent company ASSA Abloy move that product under the Yale umbrella and away from Medeco or was the Medeco Keymark line borrowed from Yale's existing designs?


On the topic of Medeco, your list has the angles as 15 degrees, isn't Medeco 20 degrees and Corbin Emhart is 15 degrees? Graham's book (p160) does list Emhart as 20 degrees, but the Medeco Service Manuals below list Medeco as 20 degrees.. I just found (p290) he also lists Medeco as 20 degrees.

Original and Biaxial Service Manuals: HERE

I just put an Emhart key up to a Biaxial key and the angle looks to be the same. Here's a pic of the two keys

I think we just stumbled unto something unexpected, as far as I know everyone here has always thought the two brands had different angles.

god i wish we had Edit.

Here's a page from the Corbin Service Manual, note angle/skew in middle paragraph bottom of page.

I hope this furthers the discussion.

Yup, it's correct; Emhart uses 20 degrees. However, I just doubled checked and Medeco is also 20 degrees! Whoops!

As for Yale KeyMark, yes there is such thing. As a matter of fact I'm staring at a Yale KeyMark Service Manual as we speak. Is there such thing as Medeco KeyMark? You bet. Are they the same thing? I dunno! Haha. http://www.reflectionsbyyale.com/pdf/Yale_Key_Mark.pdf

It's a shared technology, so to speak. Different keyways but almost identical in every other aspect: similar formats (IC, mortise/rim cylinders, etc.) and key control policies.

I'd say it's comparable to CLIQ in that Assa Abloy allow's for shared technology amongst it's companies.
