Sibbi’s stash key not opening stash in quest “promises to keep”

pcthe-elder-scrolls-v-skyrim

I am doing the quest "promises to keep" and i persuaded sibbi to give me the key to his stash.

I went to the Black Briar brewing. Went to the basement and at the bottom of the stairs is the chest. I have the key in my inventory but it will not allow me to open the chest. Keeps saying that a key is required.

Bug? Am i doing something wrong? Suggestions?

thanks!

Go to the Black briar lodge you are in Black briar meadery.

There will be two men outside in front of the lodge, an archer and a swordsman. You can either fight them and enter through the front or sneak around and open the basement door on the West side of the house.

Once downstairs, there will be a barrel in the back with the papers in a strongbox. The papers may also be found on one of the tables.
