// Bind a custom event to the lightbox that can be triggered when it needs to be dismissed:

$('.lightbox').bind('dismiss', function() {
    // code to dismiss lightbox
});

// Then just trigger that event when escape it pressed:

$(document).bind('keyup', function(e) {
    if(e.keyCode == 27) {
        $('.lightbox').trigger('dismiss');
    }
});
