Program Mercedes Vito W639 All Keys Lost with VVDI PROG and VVDI MB

If you’re a locksmith or auto key specialist facing an “all keys lost” job on a Mercedes Vito 2008 (W639), this guide is for you. I’ll walk you through the full process using the Xhorse VVDI toolchain – a reliable and efficient method we use daily. No guesswork, just clear steps.

 

Tools You Will Need:

Xhorse VVDI PROG Programmer – for reading the EIS data

Xhorse VVDI MB BGA Tool – for key programming

Xhorse Key Cutting Machine – for cutting the blade

BENZ HC08 Adapter Board – for W639 EIS reading

EIS Removal Tool Set

Lock Pick Set (optional, for non-destructive entry)

 

Step 1: Entry & Blade Decoding

1. We started by gaining access to the vehicle using a lock pick. Once inside, we decoded the door lock to get the mechanical cut code.
2. Decode result: Positions 1, 2, 3, 5.
3. This code was sent to cut a new blade using the Xhorse Key Cutting Machine. Having a physical blade ready early speeds up the whole job.

Step 2: Removing the EIS (Ignition Switch)

With the door open, we targeted the EIS. Using a dedicated EIS removal tool, we accessed it through the dash tray – the easiest route on this model.

Tip: Handle the EIS carefully. It holds all the vehicle’s key data.

 

Step 3: Reading EIS Data with Xhorse VVDI PROG

Here’s where the VVDI PROG shines.

1. Connect the EIS to the programmer using the BENZ HC08 Adapter Board.
2. Read the switch data in seconds.
3. Save the file securely.

 

This step extracts the vehicle’s “key fingerprint.” Without this data, you can’t program a new key.

Step 4: Preparing & Writing the Key with Xhorse VVDI MB

Next, we switched to the VVDI MB Tool.

1. Upload the saved EIS file via the “Prepare Key File” function.
2. The system generates individual key files – fast and cloud-based.
3. Select the key slot (we used slot 8 for this client).
4. Write the file to a blank Mercedes key.

 

The tool confirms everything: key number, SSD data, and usage counter. It’s all integrated and foolproof.

Step 5: Testing & Finishing Up

We reinstalled the EIS, reconnected all plugs, and tested the new key.
Result: The van started immediately – both the blade and transponder worked perfectly.

Why This Method is a Game-Changer

Using Xhorse VVDI PROG + VVDI MB turns a complex “all keys lost” job into a streamlined process:

• No diagnostics needed
• Fast reading and writing
• Reliable results
• Works on Vito, Sprinter, and similar Mercedes models

Xhorse Multi Prog Repair Benz W206 48V Lithium Battery

 How to repair a Mercedes-Benz 48V battery control unit with Xhorse Multi Prog?

This case highlights a common but complex fault in modern vehicles, where a simple voltage spike or battery-related event can corrupt the core software of a component, requiring deep electronic intervention rather than simple replacement.

 

The issue stemmed from a voltage spike, likely during a jump-start or battery replacement, which caused a critical failure. The module’s primary files—P-Flash 1 and P-Flash 2—were corrupted. These files contain the main microcontroller (MCU) firmware. Notably, the corruption extended beyond the main program to the D-Flash (data flash or EEPROM), which stores learned values, adaptation data, and fault histories.

 

The Repair Process: A Step-by-Step Reflash

Physical Connection: The module was connected via a dedicated programming interface. We emphasize the importance of accurate wiring, referencing saved pinout diagrams. We noted a discrepancy in official documentation regarding a specific yellow wire’s solder point but confirmed his connection method was reliable based on successful communication.

Multi-prog will show how to repair this battery module:

File Preparation and Writing: Three key files were prepared:

• A corrected P-Flash 1
• A corrected P-Flash 2
• A “cleaned” or corrected D-Flash file

The process began by erasing the old data and sequentially writing the new P-Flash 1, P-Flash 2, and D-Flash files to the module.

Verification is Key: After each write cycle, a verification step was initiated to ensure the data was written correctly and without errors. This step is crucial to confirm the integrity of the repair.

Troubleshooting a Glitch: During the procedure, the process interrupted during the P-Flash 2 verification. Undeterred, we manually restarted the write cycle for that specific file, demonstrating the hands-on problem-solving often required in board-level repair. The process then continued successfully.

Xhorse Multi Prog Volvo KVM Overcurrent with XDNP27 Adapter

 How to solve Xhorse Multi Prog Volvo KVM VDD overcurrent error when using KVM XDNP27 adapter?

This instrument is currently indicating VDD overcurrent, which means there is excessive current.
Select VDD, change from 5V to 3.5V.
We can adjust it from 3.3 to 5.2V
But we will set the lowest voltage to VDD 3.5V because this box is burned out.

If VDD still overvoltage, so we adjust it further to VCC, bringing it down to 3.5V.

Decoding the chip. The chip is currently being read.
Chip decoded successfully. This means it has now been successfully read.

Then read Flash.
