This is going to use Xhorse VVDI PROG + PCF79XX Adapter to renew a Chinese F series HUF5767 FEM key. It’s succeeded to manage in 1 minute. After refresh, the key can perfectly work on a BMW FEM F30 Car.
The VVDI PROG Adapter PCF79XX is connected on. I have not modified anything. And it seems to be working okay.
And this is the Chinese HUF5767 key which I’ll try. That’s the pin out that I’ve worked out to use.
Obviously, this circuit board is different from the VVDI PROG saying. However, I’ve got the pin out correct. Let’s go through and do the refresh now.
To do the refresh, you need to open up the VVDI Prog Software. Mine is V5.0.7 version, I believe the latest version V5.0.8 can also do it.
Select and open the F series 434M remote to renew.

We’ll see if we get any errors…
Initialization success!
Success writing.
That’s it.
It’s easy to renew the BMW FEM CAS4 key.
Then I coded it to a car it does work fine.
