Key is a key. Doesn't matter if came from a Benq or Lite-On. Don't spoof as there is no reason too. Read the key and save it. Then flash Benq original firmware with that key. Then check to make sure you did it right by playing an original disc. If works then you can update. If you spoof as another drive other than Benq the update will fail. But a Lite-On key is just like a Benq key, Samsung key, or Hitachi key.
