2016 Range rover Vogue

[drivesure]

Good day - i tried making a spare key for a 2016 range rover vogue... machine used was the autel im608. stripped the kvm and removed a crystal and a resistor and soldered wires on to mcu. i read but the d flash reads blank....only fff....eeprom reads good.

the vehicle remote and keyless function not working anymore and only starts with emergency start on side of steering.
i can read the eeprom, can i load another d flash from other kvm ontu unit and will that restore the kvm. must i load a new kvm dflash and eeprom on to unit and try to adapt that to the car.

does any one have a dflash and an eeprom of a VOGUE i can try.

any advice what my options will be to get the car going.

really appreciate any advice with regards this vehicle .

regards

Happened to us all sadly very easy to damage these cars.

trouble is so many flash versions out there you might be better just replacing KVM - or better still virgin existing unit and use sdd to code
