    2. He soldered the new mcu into the used remote what included an old (used/locked) PCF7936 transponder.
    3. He resyncronized the remote to an other car with a universal scan tool.
    3. He resync the remote to his car , the kob there is remote board with new motorola chipset , and old transponder chipset which was paired with the car before.

    So the used PCF7936 belongs to the car.
    How can he to program the blank Motorola mcu?
    This is not clear for me.
    Does car write the dump into the mcu under remote resync process?

    I made a Peugeot 307 remote with mihotd's help 1 month ago.
    First I had to read the data from the Motorola mcu.
    Then mihotd collegue calculated a dump for PCF7936. His dump included the remote ID.
    So the remote ID there is in the mcu.
    It is 100%.

    I don't know whether that one motorola chipset is a MCU inside or it is just a non-intelligence logic circuit to do rolling code algorithm without a MCU.

    Did you try this way, just write the 3rd line into transponder then pair and sync the knob with car?i.e. the car only need to know the remote type then know how to decode it, the car don't need to verify something of remoteID.

    Maybe , because we are just vehicle owner but not industry people, we heard info from different channel but no chance to verify it.
