Lonsdor K518 Pro 2020 Range Rover Sport Keyless Not Working Solution

Problem:

I got a customer has 2020 range rover sport.
New type key
I believe that that car has lost its keys before and some one did a key for it that start only with emergency and remote working normally( Lonsdor key).
The customer wants to do a key that works normally with keyless functions.
So the only method i got is to do RFA replacement and everything willl works normally?
Here some info got it from lonsdor k518 pro.

Solution:

If its PEPS key (passive entry, passive start) , you have to replace mcu in rfa module. Due to UWB function key clone wont work for keyless start.
Turn uwb off.
And add 2 Lonsdor keys.

Option 1 easy method. If you have autel, try generating a key in autel and hopefully everything works. If not….
Option 2. Replace SPC mcu in RFA. Write back proper calibration. Then add keys via obd.

RFA remplacement or MCU of RFA remplacement if you have soldering good skilks.
You need to replace the mcu and write data then program to car.
