Custom Post Type Slug Problem

I can’t get my produkt.php to work, and understand there’s something wrong with my page slug.
I tried archive-produkt.php and produkt-archive.php and several other names.

This is the code in my functions.php, so if someone understand what’s going on here I will send you a virtual flower.

// Register Custom Post Types
add_action('init', 'register_custom_posts_init');
function register_custom_posts_init() {
    // Register Products
    $products_labels = array(
        'name'               => 'Produkter',
        'singular_name'      => 'Produkt',
        'menu_name'          => 'Produkter'
    );
    $products_args = array(
	'slug' 		     => 'produkt',
        'labels'             => $products_labels,
        'public'             => true,
        'capability_type'    => 'post',
        'has_archive'        => true,
        'supports'           => array( 'title', 'editor', 'excerpt', 'thumbnail', 'revisions' )
    );
    register_post_type('produkt', $products_args);
}
