SSRS encryption keys are broken

I had an SSRS service account password expire. This is on an Azure Windows server. I've tried the following: - Updating the password caused "The report server can’t access or use the encryption key" - Attempting to delete the key via all the normal methods fails. - Manually deleting the key (keys table) doesn't give me an option to re-create a new one. The only solution I can think of at this point is un-installing and reinstalling SSRS. Is there a better way, or is this approach even likely to work?
