Program Citroen Jumper 2021 95640 All Keys Lost with VVDI Key Tool Plus

 Losing all keys to your Citroën Jumper 2021 can be a frustrating experience, but with the right tools and knowledge, it’s possible to program a new key. Below is a step-by-step guide based on a real-world procedure performed by an automotive locksmith.

Tools and Equipment Required

• VVDI Key Tool Plus – Necessary for direct key programming.
• EEPROM adapter – Used to read and write data from the immobilizer chip.
• Soldering equipment – For carefully removing and reinstalling the chip.

Step-by-Step Procedure

1. Accessing the Immobilizer Module

• The immobilizer module in the Citroën Jumper 2021 is located behind the dashboard.
• Carefully remove the casing by releasing the side and top clips to avoid damaging the connectors.

2. Removing and Reading the EEPROM Chip

• Locate the EEPROM chip (95640) on the immobilizer board.
• Desolder the chip gently to avoid damaging the circuit board.
• Solder the chip onto an EEPROM adapter to read its data.

3. Extracting Key Data and PIN

• Identify the stored key data and extract the vehicle’s PIN code.
• The dump revealed two existing keys, but the goal was to program four new keys.

4. Writing Key with vvdi key tool plus

• Prepare new key transponder chips by writing the extracted PIN and new key data.
• Each key was programmed sequentially, with the fourth key added to the immobilizer’s memory.
• Verify that all four keys were successfully written before proceeding.
• Save new key data

5. Write new key data back to EEPROM

• Write the new key data back to eeprom.

6. Testing the New Keys

• Solder the EEPROM chip back onto the immobilizer board.
• Reassemble the module and reconnect it to the vehicle.
• Repeat the test with the second, third, and fourth keys to ensure all work correctly.

Done.

Xhorse Multi Prog Clone Volvo Bosch EDC17CP22 ECU

 In this guide, we’ll walk through the process of cloning a Volvo S60 (2014) Bosch EDC17CP22 ECM (Engine Control Module) using Xhorse Multi Prog programmer. The original ECM had issues—check engine light was on, and the car wouldn’t start—so we replaced it with a used ECM and transferred the data from the old module.

Step 1: Preparing for ECM Cloning

Before starting, ensure you have:

• Multi prog (or a compatible programmer).
• Donor ECM (used/replacement unit).
• Original ECM data backup (critical to avoid programming errors).

Why Multi prog?

• No extra wiring needed—it has built-in schematics for easy connections.
• Supports reading internal and external flash memory separately.
• Faster and more reliable than other tools.

Step 2: Reading Data from the Original ECM

1. Connect Multi prog to the old ECM (power, ground, and ignition lines).
2. Read three sets of data:
   • Internal Flash
   • External Flash
   • EEPROM (critical immobilizer and calibration data).
3. Save all files securely—corrupted data can brick the ECM.

Note: Reading may take 4-5 minutes per section, and full backup is necessary before proceeding.

Step 3: Writing Data to the Donor ECM

1. Connect the replacement ECM to Multi-prog.
2. Load the saved files (internal flash, external flash, and EEPROM).
3. Write each section separately (Multiprog does not support full-file writing).
   • External Flash: ~8 minutes.
   • Internal Flash: ~1 minute 19 seconds.
   • EEPROM: ~2 minutes 2 seconds.
4. Verify successful writing—the tool will confirm completion.

Step 4: Testing the Cloned ECM

After writing:

1. Install the cloned ECM in the vehicle.
2. Turn on ignition—check for error lights.
3. Start the engine—if cloning was successful, the car should start normally.

Important: If the car doesn’t start, recheck:

• EEPROM data (most immobilizer issues come from incorrect EEPROM cloning).
• Power and ground connections to the ECM.

Done.
