Only HDD's have keys matched to the EEPROM, though you can lock a new HDD with a matching key.
Duh..... I had HDD on my mind. 
The DVD drives are totally interchangeable, but do have those funky connectors though. 
So yeah, another dead box, or ordering one. 
A standard drive can be made to work, but not such a pretty install. 
Or possibly tear into the drive and clean the laser assembly, that cures a lot of non-reading drives. (unless it's just dead dead)
