My understanding is the powertrain control module needs to be unlocked before it can be programmed by a DRBiii or DAS Star tool. It’s programmed with VIN, secret pin for the Skreem, country etc.. There are companies that will repair the original PCM for $250-300. Some companies also offer cloning of the PCM to another working/reconditioned PCM....that appears to be more expensive $500-800 range.
