I see - then I recommend that you reNAME both elements to 'txtKeyValue[]'.
this will cause php to create an array for you so you can always get to
both values. e.g.
print_r($_POST['txtKeyValue']); // Array
that will give you a numerically indexed array, if you rename the textboxes
individually to 'txtKeyValue[default]' and 'txtKeyValue[other]'
you will have an associative array with a structure like:
$arr = array(
'default' => 'ABQIAAAAh2cCTTmAE6T4OXjecIFe5BQMxb4e6BwgeSB7cBu9SbVQSak6ARTgAPoctbx36BXXgbYZONZls0B1LQ',
'other' => '',
);
there is no intrisic need to give the elements an id at all (regardless
never give 2 elements on one page the same id.)

I like switch statements, my favorite is the rather evil use
of switch()'ing on true:
switch (true) {
case (/* arbitrary boolean expression */):
break;
// .. and so on
}
