**To associate an alias with a different KMS key**
The following ``update-alias`` example associates the alias ``alias/test-key`` with a different KMS key.
* The ``--alias-name`` parameter specifies the alias. The alias name value must begin with ``alias/``.
* The ``--target-key-id`` parameter specifies the KMS key to associate with the alias. You don't need to specify the current KMS key for the alias. ::
aws kms update-alias \
--alias-name alias/test-key \
--target-key-id 1234abcd-12ab-34cd-56ef-1234567890ab
This command produces no output. To find the alias, use the ``list-aliases`` command.
