Documents.Open(strTemplateDoc, ReadOnly:=True, PasswordDocument:=strDocPassword, Visible:=False)

Setting the View.Type to wdNormalView stopped the error "You are not allowed to edit this selection because it is protected"

wdDocPage.ActiveWindow.View.Type = Microsoft.Office.Interop.Word.WdViewType.wdNormalView
