One customer asked the difference between these two clone functions on his VVDI Key Tool Max: HCS/Fixed Code Clone and Special Clone.
Here are the Differences:
1)HCS/Fixed Code Clone
Normal/ Fix code always maintains same rf and pulse.
Only supports a few very old vehicles.
2)Special Clone
Rolling code changes as you go using the controller.
Key clone will void original key.
Wire Remote is required.
Hope this could help!
