They seldom come with keys, you were lucky.
As I said I love Empire furniture. I have many pieces in my house. It’s solid and impressive but still beautiful.
Actually, I was taking the brass off and planning on selling the hardware on eBay...when I came across the key...that was the clincher b/c it has 2 lockable doors and 1 lockable drawer. It’s a very useful piece of furniture. ;)
