Cloning an ignition switch (EIS) for Mercedes-Benz vehicles like the W215/W220/W230 model can be a cost-effective solution for replacements. In this guide, we’ll walk you through the process of cloning data from the original EIS to a replacement unit using an Xhorse VVDI Prog programmer.
Tools Required
-
Original and replacement EIS (Part number: 2305450708)
-
Mercedes key (from the original ignition switch)
-
Pinout adapter (for testing)
Step-by-Step Process
1. Reading the Original EPROM Data
In VVDI Prog software, select Benz-Immobilizer- Benz- WIS-W230(W215) 4J74Y
Check wiring diagram.
Connect the original EIS to the VVDI programmer.
Use the software to read the EPROM data from the original EIS. This data contains critical information needed for the replacement unit.
2. Transferring Data to the Replacement EIS
-
Connect the replacement ignition switch EIS to the VVDI programmer.
- Back up the eeprom data of the replacement EIS module.
-
Write the original EPROM data onto the replacement unit. This ensures the new EIS will recognize the vehicle’s keys and function correctly.
3. Testing the Replacement Ignition Switch
-
Use the pinout adapter from VVDI Prog to simulate the EIS connection.
-
Insert the original key into the replacement EIS.
-
If the cloning was successful, you should hear a click, indicating the key has been detected.
-
Turn the key to verify the ignition switch operates properly.
Conclusion
By following these steps, you can successfully clone a Mercedes W230 ignition switch using a VVDI Prog programmer. This method saves time and money compared to dealership replacements.
