Some users reported that VVDI MLB remotes stop working after 2–8 weeks, while keyless start still works and the original key is fine.
Solution 1:
Update the VVDI MLB key firmware to the latest version.
It will give you 2 option when you press update.
In VVDI MLB Tool software, go to Update Online->Upgrade OEM keys to update VVDI MLB key.

You can resync remote again via obd but he will come back again in 2 months.
Solution 2 (Hardware Fix)
If the firmware update doesn’t help, technicians found a new fix:
Remove the small diode on the PCB and short the two solder points.
This improves power stability, fixes battery issues, and restores remote function.

User Feedback
“I modified 4–5 keys like this. After removing and shorting the diode, none came back. Problem solved.”
