Replacement of Locked SPC560B60L3 Microprocessor for a 2019 Range Rover: Virginization and Writing of RFA Initialization Data using Keydiy KD-X4.
On models from that year, the SPC is locked; you cannot read from or write to it. You have to swap in a new one in order to write the data and proceed with the programming. This is a scenario typical of All Keys Lost (AKL) situations on Range Rover vehicles.
The choice is between replacing that specific microcontroller or replacing the entire RFA module.
Swap it out for a virgin unit.
Write the data, then pair and synchronize the system to ensure everything is fully functional.
