This whole topic is so stupid.
If you have an original Liteon drive, either put wholesale from the maker, or one from inside a 360 that was never modded before, you can easy change the dvd key.
All drives running stock fw, have a simple cdb command which can upload/update the drive key by themselves, also long as the drive is up and running, you can change the drive key, you can't read it back,
but you can write it.
How dumb, anyone can offer this service, you don't need to have the original liteon firmware, just a good supply of untouched liteon drives.
You do need to know how to send the cdb command, current programs don't support just uploading the drive key, as most people want to read their existing key, if that was in a modding program you would end up with lots of people wiping their key, and complaining.
But it can be done with lots of simple existing command line tools which can send cdb commands to the drive.
Shit, I could offer this service also, but currently I am buying wholesale the BenQ drives as they are only $12.48 each in lots of 10, but if that supply runs out, no problem start buying stock original Liteon drives.
