Benz W210 All Key Lost with Xhorse VVDI Key Tool Plus

The Xhorse VVDI Key Tool Plus Pad provides a solution for programming a Mercedes-Benz W210 in an all-keys-lost scenario directly on the bench. The entire process can be completed in four main steps. Follow the detailed procedure below.


Step 1: Save EIS Data


Navigate to: IMMO Programming >> Europe >> Benz >> Select from system >> EIS tools >> Start programming >> Auto detect (CAN)

Save the EIS data file to a secure location.

Step 2: Password Calculation


Navigate to: IMMO Programming >> Europe >> Benz >> Select from system >> Password calculation >> Start

The tool will display "Acquisition finished". Upload the EIS data file you saved in Step 1 using the "Upload Data" button.

After a successful upload, the VVDI Key Tool Plus will automatically begin calculating the password. This process takes approximately 50 seconds.

Once completed, the message "Password has been successfully read out" will appear.

Save the newly generated EIS file, which contains the password.

Step 3: Generate Key File


Navigate to: Prepare key file >> Start programming >> Prepare key file

Load the new EIS file (the one with the password) that you saved in the previous step.

The key file will be generated. A "Key file generation completed" message will confirm that the process is finished.

Step 4: Write New Key


Navigate to: Read write key >> Read/Write key via IR >> Start programming >> Write BE key

Load the key file that was generated in Step 3.

Insert the new BE Key into the infrared antenna on the Key Tool Plus device.

The tool will write the data to the key. A "Writing data success" message indicates a successful operation.

Important Note: If the key is a smart key (BE), you must first install the battery and then wait approximately 1 minute before attempting to program the key to the car. During this time, the key's LCD screen will flash.


The key programming is now complete.
