Issue:
BMW F Series (CAS4/FEM) remote key (ID HUF5661) is locked which has been identified with KEYDIY KD-X2 remote maker.
Solution:
Use VVDI Prog and PCF79xx Adapter to unlock (renew) this remote key.
The steps:
Remove the PCB from the BMW CAS4/FEM remote key
Plug PCF79xx Adapter on VVDI Prog programmer
Connect PCF79xx Adapter and BMW CAS4 remote
Connect VVDI Prog to computer
Plug the power supply to VVDI Prog as well
Run VVDI Prog software
There are two options on the top right corner: Set Protect and Reset Protect
The software shows read data error after selecting BMW type, brand and chip to read data directly.
So need to reset Product to read data again.
Now read data successfully
Load the original EEPROM data to write in
Write success
Then also load EROM data from VVDI to write in
Operation is successful
After that, Set Product in the software interface
Initialization success
Then read the transponder via KD-X2 again
It’s unlocked now.
