Keys is "all washed up" as well
Once Mr. Norton gets to work and learns of this corporate and public relations catastrophe, I doubt he will allow his adjuster, Mr. Barton Keys, to continue working at the company. Don't forget, Mr. Norton actually suspected Walter Neff had something to do with the Diekrenson case. It was Keys who put that hunch to rest by checking Neff's alibi the night of the murder and personally vouching for Neff.
No, I can't see Norton allowing Keys to continue in his capacity as insurance claims adjuster. Not to mention how the man, himself, must have lost all of his confidence. Maybe Keys just handed in his papers and went looking for Margie.
