Sierra: Click the Lock Not Working

I installed Sierra yesterday and it seemed to totally screw up my keychain. Spent hours on the phone with very helpful Apple support and can get the system booted but under system preferences anything that has a "click the lock to make changes" icon is not working. I click and it flickers but nothing happens. This means I have no access to advanced settings As with El Capitan, there is no "repair permissions" function under First Aid.

Thanks for any suggestions.
