I also have a ring of 75+ non-DEC smaller (non-door) keys with everything from telco cabinets to fire alarm pullboxes to filing cabinet masters. I'll consider requests for copies from people with a valid justificiation for needing one (and again, cylinder face number codes will help).
Here's the first of the non-DEC key lists. Let me know if this is too off-topic and I'll stop. But maybe it will help someone identify a key they need:
