WordPress | Sortby & filter - Archive page

My code:

<?php
$the_key = 'upsidedate';  // The meta key to sort on
$args = array(
   'meta_key' => $the_key,
   'orderby' => 'meta_value',
   'order' => 'ASC',
);
global $wp_query;
query_posts(
    array_merge(
        $wp_query->query,
        $args
    )
);
?>
<?php 
if (have_posts()) : while (have_posts()) : the_post() ;

get_template_part('post', 'archive');
endwhile;

else :
    get_template_part('post', 'noresults');
endif; 

get_template_part('navigation');
?>

What is doing now? its order by the custom field "upsidedate".

I want to order by the custom field "upsidedate" and filter by the custom field "done", I mean only if the value on "done" is "no" - it will show the post on archive.

Should be something like that:

$the_query = new WP_Query( array( 'meta_key' => 'done', 'meta_value' => 'no' ) ); 

But I cant use meta_key twice. How can I do that?
