Those look like Best keys, could go to anything requiring a solid locking mechanism. It is also worth noting that the keys are not identical, but probably belong to the same facility. What did he do for a living?

7-pin Best keys
Could belong to the old Hughes aircraft facility or GD, but I highly doubt they are safety deposit box keys judging by the shoulders and notches. Deposit box keys usually have squared shoulders and notches. They look like they're older keys used for storefront doors or safety doors like an aircraft facility might use.
His official job was lead electrical engineer and worked on numerous military contracts for hughes/GD. He was one of the few people who designed the Maverick and a few other explodey things.
Just checked and one of the keys does say BEST right below the keyring hole.
That's what my mom thought they were. She remembers him having them on his car keychain when he was working in there the 1980s.They look like government keys. I've had almost identical ones for various old buildings and barracks that i've lived in on military installations.

Mystery (likely) solved. I can almost guarantee those keys will no longer open any door as they belonged to big safety doors which change locks frequently, and he kept them on there for posterity's sake. Hold on to them as a memory of who he was and what he did, I think that's what he would have liked. My grandfathers were the same way
