    Problem:

    I tried to add a smart key for yamaha 2021 by Xhorse vvdi key tool plus / i read the eeprom by welding/ and i succeeded to generate dealer key / but when i want to write back the file it gives me erase error !
    I was able to get the code by key tool plus. But i want to add key by writing it not that manual method because already everything is done just the last step not gone well.

    Solution:
    Can not write back eeprom – use pin number to add key manual on scooter.

    Or use other device. kdyz has a adapter that works with phone to add if uyou have original pin number – did one yesterday Yamaha 2022 all keys lost.
