Hello everyone,
I’m working on a Renault Clio IV (VIN: VF15RBF0A60946244) with a virgin HFM Continental 285900636R module. The original HFM is lost, but I have the full ISK (16 bytes) extracted from the ESCL (steering lock) 24C04 

I’m using Renault ECU Tool v4.13, and when I try to inject the ISK manually into the virgin HFM, the procedure fails with this message:
"Learning ISK to HFM... FAILED"
"ERROR_5 - Key/Card blank or does not belong to this car"
Here’s what I’ve tried:

• Read ECU (EDC17C84) – ISK not present in data flash (normal)
  
• Read ISK from ESCL – confirmed valid 16-byte key
  
• HFM is detected as blank, no VIN or key stored
  
• “Write Code” function with known ISK selected – fails after confirmation
  

Any help or experience is greatly appreciated!
Thanks in advance
