+## Updating Your License Key
+
+Whenever you purchase a new Telerik UI for .NET MAUI license or renew an existing one, always [download a new license key](#downloading-the-license-key). The new license key includes information about all previous license purchases. This process is referred to as a license key update. Once you have the new license key, use it to [activate the Telerik UI for .NET MAUI](#activating-the-telerik-ui-for-net-maui-components).
