How to Force Unlock Terraform State Safely
Use the
terraform force-unlock command followed by the lock ID to manually unlock a Terraform state when it is stuck. This command safely removes the lock so you can continue working without corrupting the state.Syntax
The terraform force-unlock command requires the lock ID as an argument. Optionally, you can specify the workspace with -force-unlock LOCK_ID [options].
- LOCK_ID: The unique identifier of the lock to remove.
- -force: Confirms you want to force unlock.
bash
terraform force-unlock LOCK_ID
Example
This example shows how to find the lock ID from an error message and then force unlock the Terraform state.
bash

Always ensure no Terraform operations are running before forcing unlock.
bash
terraform force-unlock wrong-lock-id # Error: Lock ID not found # Correct usage: terraform force-unlock 1234abcd-12ab-34cd-56ef-1234567890ab
