Are you using a flex app?It could be that flex is getting this event before your code does.Could you please try increasing the the priority of you event listner, when adding the listener using the addEventListener call.

private function key_down_handler(event: KeyboardEvent): void
{
	if (event.keyCode == Keyboard.BACK)
	{
		event.stopPropagation();
		event.stopImmediatePropagation();
		event.preventDefault();
	}
}
