<a name="example_lambda_UntagResource_section"></a>

The following code examples show how to use `UntagResource`.

------
#### [ CLI ]

**AWS CLI**  
**To remove tags from an existing Lambda function**  
The following `untag-resource` example removes the tag with the key name `DEPARTMENT` tag from the `my-function` Lambda function.  

```
aws lambda untag-resource \
    --resource arn:aws:lambda:us-west-2:123456789012:function:my-function \
    --tag-keys DEPARTMENT
```
This command produces no output.

#### [ PowerShell ]

**Tools for PowerShell V4**  
**Example 1: Removes the supplied tags from a function. The cmdlet will prompt for confirmation before proceeding unless the -Force switch is specified. A single call is made to the service to remove the tags.**

Remove-LMResourceTag -Resource "arn:aws:lambda:us-west-2:123456789012:function:MyFunction" -TagKey "Washington","Oregon","California"
```
**Example 2: Removes the supplied tags from a function. The cmdlet will prompt for confirmation before proceeding unless the -Force switch is specified. Once call to the service is made per supplied tag.**  

```
"Washington","Oregon","California" | Remove-LMResourceTag -Resource "arn:aws:lambda:us-west-2:123456789012:function:MyFunction"
```
