Note When you lock a file (using Box's locking feature), you will see a lock icon, but you are still be able to edit the file. If another user locks a file, any collaborator with Co-owner, Editor, or Viewer Uploader access can unlock it.

If you're unable to unlock despite your permission, please troubleshoot then try again.
