How do I unlock my Canvas course?

Canvas courses are locked in read-only mode after the term ends (or course end date passes). It is now possible for instructors to unlock courses to allow course members to interact with it again (add/edit content, send messages, etc.)

Unlock Course

To unlock a past course, follow the steps below.

  1. Go to the concluded course (Courses > All Courses > Past Enrollments > select desired course).
  2. Click Settings from the left-hand course navigation. 
  3. On the right side of the page, click Unlock Course.

  4. The following message will display to let you know that, by default, the course will be unlocked for 7 days. You can adjust the course Participation End date or manually lock the course again once the course is unlocked. Click Submit.
  5. After the page refreshes, verify that the course is unlocked by confirming that the Lock Course link is present and the course has a future Participation End date.

Note: Once a course is unlocked, the course may reappear on student Canvas dashboards. Students will be able to interact with the course (e.g., post discussions, submit assignments, etc.) until the course is locked again. 

Modify Course End Date

By default, unlocking a course automatically activates the course for 7 days. However, you can set a shorter or longer duration for the course to be active depending on your needs. To do so, follow the steps below. 

  1. Go to Settings > Course Details
  2. Scroll down to the End date. 
  3. Using the calendar picker, choose the desired end date.
  4. Scroll down and click Update Course Details

Lock Course

If you no longer want the course to be active, follow the steps below to lock the course. You can always unlock the course again. There is no limit to how many times you can lock and unlock a course.

  1. Go to Settings > Course Details
  2. Click Lock Course.
  3. Once the page refreshes, verify that the course has been locked by confirming two things:
    1. The Unlock Course link is present.
    2. The End date will display the current date and time.
