# Use `DisableKey` with an AWS SDK or CLI
The following code examples show how to use `DisableKey`.
Action examples are code excerpts from larger programs and must be run in context. You can see this action in context in the following code example:

///
/// Disable an AWS Key Management Service (AWS KMS) key and then retrieve

#### [ CLI ]
**AWS CLI**
**To temporarily disable a KMS key**
The following `disable-key` command disables a customer managed KMS key. To re-enable the KMS key, use the `enable-key` command.
```
aws kms disable-key \
--key-id 1234abcd-12ab-34cd-56ef-1234567890ab
```
This command produces no output.
For more information, see [Enabling and Disabling Keys](https://docs.aws.amazon.com/kms/latest/developerguide/enabling-keys.html) in the *AWS Key Management Service Developer Guide*.
