What bank did Francis Scott Key use in the later part of his life?

Question

I'm asking this because two pieces of artwork that I believe belonged to a bank in Washington D.C. On the back of one it says that Francis Scott Key was a customer to their bank in the later part of his life. It does not say the name of the bank, so I'm trying to find out.

Answer 1

He only used the ATM at 5th and Main at Bank of America.

Answer 2

He probably banked in Baltimore because that's where he died.
