How to get keychain to leave me alone?
This problem was with the "local items keychain". I found the following here and it worked for me:

Follow these steps to prevent prompts to unlock the Local Items keychain.


In Finder Select Go > Go to folder (⇧⌘G)
In the window that appears, type the following:
~/Library/Keychains/
Click OK.
Look for a folder with a name similar to this "A8F5E7B8-CEC1-4479-A7DF-F23CB076C8B8". 
Note: Each folder has a unique number.
Move this folder to the Trash.
Immediately choose Apple Menu () > Restart… to restart your Mac.


After restarting the computer, a new folder is created in the Keychains folder with a name similar to "4B29A0BB-599D-47FC-A2D1-42B5592B130B". There is no need to repeat the steps in this article, or to delete this folder. The new folder is expected and corrects the symptom described in this article.
