Today I’m going to use the Xhorse VVDI Prog & VVDI Key Tool Plus to program 2004 Mercedes Benz C240 when all keys lost on bench. I took out the EIS to program key in a fast way.
Tools
A Mercedes 209 EIS
There are W209/211 ZGW and W209/211(HC12) adapter in my box, but I won’t be reading it as a 209. Instead I’ll read it as 211, different variations of this 209. So what I’m going to use is the W211(ST12) adapter.
Install EIS on W211(ST12) adapter, connect it with VVDI Prog & computer.
Let’s start:
Read & Save EIS Data via VVDIProg
Start VVDI Prog software, select correct info on right side options, click
EEPROM >> Read >> Operation success
Verify >> Check success >> Save
FLASH >> Read >> Operation success
Verify >> Check success >> Save
Everything was good, save EEPROM & FLASH file success.
Transfer the files to Key Tool Plus for next step.
Program Key via VVDI Key Tool Plus
Disconnect VVDI Prog, replace Key Tool Plus for connection, press
Immo program >> Europe >> Benz >> Select from system >> Prepare key file >> Start programming >> Prepare key file >> OK >> Load EEPROM file >> Yes >> OK >> v051
Insert Benz Smart Key into the infrared antenna of Key Tool Plus.
Calculating require 30s, please wait…
OK >> Save here >> OK
It is preparing all keys, wait until 100%…
Key file generation completed, press “OK”.
Go back to
Read write key >> Read/write key via IR >> Start programming >> Infrared identification key information >> OK >> Continue >> Erase the BE key >> OK
Erase success!
Infrared identification key information >> OK >> Continue >> Write BE key >> OK >> Load data file >> OK
Writing data success.
If key is smart key(BE), please install battery and wait 1 minute before learn key to car!(The key LCD will flash during this time!)
Activate Key
The activation key generally directly inserted into the car to activate, if you cannot activate, please try the following methods:
- Manual activation by select from “system >> read write key >> read/write key via IR >> activate”;
- Read EIS data again and generate key file again;
- Try to unplug the OBD connector, inset BE key into EIS to activate.
Unplug the W211(ST12) adapter, setup the EIS back to car together.
Insert the key into ignition, it can start the engine, and its remote works.
Success!
Using VVDI Prog + Xhorse Key Tool Plus is much faster than Autel. The Autel is telling to take 20-40 minutes for password calculation while Xhorse does not. Take out the EIS to read & program by Xhorse tools rather saved me lots of time.
