Is your example above as it is in your code? If so you've got the options as two separate parameters which is why it'll work when you comment it out.

Try

echo Html::activeDropDownList(
    $model, 
    'client_key',
    ArrayHelper::map(ListClient::find()->all(), 'client_key', 'cli_stat_name_l'), 
    ['prompt'=>'All Clients...', 'onchange'=>'this.form.submit()']
);
