View and Manage Locks

From time to time it might be necessary to examine or delete locks placed on elements by users. Enterprise Architect provides a function to view and manage active locks.


  • You must have Security - Manage Locks permission to view and delete user locks; the initial Admin administrator automatically has this permission.
  • If an element is locked, connectors attached to it are also locked. To unlock the connector, you must unlock the element. However, under certain circumstances you can add new connectors to a locked element.

Delete a Lock

To view locks and, if necessary, delete them, follow the steps below:

  1. Select the Project | Security | Manage Locks menu option. The Active Locks dialog displays.
  2. In the View Locks For panel, click on the radio button for the type of lock to view: All, Groups Only or Users Only. Locks of the appropriate type are listed in the Active Locks panel. If you want to display the resulting information in a more readable layout, you can resize the dialog and its columns.
  3. To remove a lock, click on it and click on the Unlock Selected button.
  4. When finished, click on the Close button to close the dialog.
