The keyblank is an Ilco 1041G, aka CG1, which looks like this: http://mysecuritypro.com/images/products/highres/cg1large.jpg Note that there are other similar blanks in which the center land is offset one way or the other, but on this one it's centered. One easy way to get one is on ebay: H2007 is one of the relatively common numbers, once used in alarms or elevators or some such. Most real locksmiths (i.e. not the key booth at Ace or Home Despot) will have the means to originate such a key, and can work from "Chicago double-sided H2007 CG1". Many of said serious locksmiths will want you to prove you own the lock. I think I remember hearing that Jay carried one of his HP minis into such a place once... ;) TL;DR: The tricky bit to cutting them is that when Chicago designed them, they developed several hundred unique curves instead of a set of numbered cut depths. However, manufacturers of numerical key machines have worked it out, probably by pretending there are a large number of cut positions. There are two ways these days to originate one: copy the appropriate master key (they come in sets from whoever now owns Chicago, or used from ebay occasionally) onto the appropriate blank; or use a numerically controlled key machine. I can originate most of these Chicago keys from my set of masters, if people are stuck. I think I can also produce the 4T1427 panel lock key, and with a little testing the tubular XX2946, XX2247, XX2065 (since we have cut depths for these). I've been trying to get to the point where I can produce most ccmp related keys, and am interested in expanding that capability, if people have needs or additional data. De
