  1. Change all cron jobs and scripts that use the site key for authentication
  2. Reenter any passwords, specifically payment processors and mail/sms passwords
  3. All prior checksums sent in the last 7 days (if that value has not been changed), will no longer work
  
  A grep for SITE\_KEY in the code base will uncover a few more things :)
