2018 VDJ200 VXR 8A (A8 SLK03) Unable to add key by OBD or by dump

Hi there, so I have a case on a 2018 land cruiser VDJ200 VXR, client requested to add key, however, when I go to learn key utility in tango+, after ignition on it requires to bring existing key close to push button, when I do so, it is as though the key is not recognised, the working key only works by keyless start and can't start without its battery, I also read the smart ECU 93C66 eeprom but when load into tango, it says unknown version, so I assume dump is somehow corrupted or immo info is in MCU ? Any help will be appreciated

Attached below smart box ID and part number and dump read by orange5 and tango+

Existing key original or China? Immo data is in MCU. Press "read data from car" and write emulator SLK03. Use emulator for "learn key"
