We got a 2006 Mercedes-Benz ML350 with all keys lost from customer. So we’re gonna use Xhorse VVDI Key Tool Plus + Benz EZS/EIS Adapter to program a new key for it.
We’ve removed the HVAC panel, and there are 2 T15 torque screws. Just unscrew those and the radio will just come out. Then unscrew the little ring that holds the EIS, and unhook these 2 cables. It’s very simple and fast.
- Read EIS Data
We’re using the W164 adapter to read EIS immo data. With it, we don’t have to solder, which should be a fairly simple job. There are 2 sets of data that are stored on the EIS: Eeprom & Flash. Read them and make a backup copy of both files.
Prog >> IMMO >> BENZ >> EIZ – W164-ST12 >> Adapter >> Read >> EEPROM/FLASH
- Generate Key File
Immmo programming >> Benz >> Select from system >> Prepare key file >> Start programming >> Prepare key file >> Load EIS EEPROM file with password >> Yes >> Confirm the key password >> v051
Require 30s, please wait…
Calculate success.
Save the file.
Key file generation completed.
- Write Key File
Read write key >> Read/Write key via IR >> Start programming >> Write BE key >> Load key file
Please insert the new VVDI BE Key into the infrared antenna of the Key Tool Plus.
Writing data success.
Insert the key into the car EIS to activate.
If activation failed, follow the manual instruction.
Test the new key.
Remote function work, and the car is running.
All done!
