Hi all,
I have accidentally become the unofficial locksmith for my family, as 3 of us now own ~century-old New England homes and have an interest in keeping the original door locks intact if possible, while still being able to lock our doors. My front door has a Corbin S24 keyed lock and my aunt's has an S31. I have not checked what my parents has yet (as they have no original keys and I haven't dropped by since they asked me about this.) However, finding keys for these old locks is somewhat difficult as none of the locksmiths near us are old-school enough to have even blanks, and certainly don't have any factory precut keys on hand anymore. From disassembling my lock and cleaning it out, I've learned a bit, and from buying random S series keys on eBay and Etsy and modifying them to work, I've learned a bit more, but this forum consistently came up in my research on Google so I figured I'd join. Does anyone have any Corbin S series keys? I am also interested in P, Q, R, H, and other Corbin series, but mostly curiosity only at this point, while S series I have a vested interest in. I would like to compile as much information as I can on these keying series and publish it so that others in our position can make keys for their locks instead of giving up and replacing them with modern locksets.

I am most interested in buying keys (specifically S6, S22, S24, and S31 at this point, but all S series accepted - especially if you post pictures and I determine I can machine them to fit S24 or S31) but if you want to keep them in your collections and just post high resolution photos of both sides of the key, that would also help a lot.

Keys I already have, or have info on:
S6
S22
S24
S31

The deadbolt lock I have seems to be a combination of warded and lever lock designs. It also has an interesting pushbutton lock/unlock mechanism in the mortise and a second, smaller keyhole on the outside only that can be used to lock and unlock the doorknob. I have not removed it from the door in a while but have some cellphone photos of its inner workings if anyone would like me to post them.
