    18  ## Description
    19  
    20  Unlocks a locked manager using a user-supplied unlock key. This command must be
    21  used to reactivate a manager after its Docker daemon restarts if the autolock
    22  setting is turned on. The unlock key is printed at the time when autolock is
    23  enabled, and is also available from the `docker swarm unlock-key` command.
    24  
    25  > **Note**
    26  >
    27  > This is a cluster management command, and must be executed on a swarm
    28  > manager node. To learn about managers and workers, refer to the
    29  > [Swarm mode section](https://docs.docker.com/engine/swarm/) in the
    30  > documentation.
