Xhorse VVDI Key Tool Plus + Condor II Program 2005 BMW E46 EWS3 All Keys Lost

Replacing lost keys for a 2005 BMW 3 Series (EWS3 System) used to be a dealer-only nightmare. Today, the combination of the Xhorse VVDI Key Tool Plus + Condor II makes this complex job efficient and profitable.

 

This guide outlines the professional bench method for programming a new key when all keys lost.

 

Essential Tools Required

• VVDI Key Tool Plus: The all-in-one tablet for IMMO programming.
• Condor XC-Mini Plus II: A high-precision automatic key cutting machine.
• Lishi HU92 2-in-1 Decoder: To decode the door lock without disassembly.
• Soldering Station: For connecting the MCU cable to the EWS module.

 

Step 1: EWS3 Module Removal

Since the 2005 BMW 3 Series (E46) uses the legacy EWS3 security system, direct OBD programming is not possible. You must perform a bench read by removing the module located behind the driver-side lower dash panel.

1. Safety First: Disconnect the vehicle battery located in the trunk.
2. Access the Module: Remove the driver-side dash panel by unscrewing the three retaining screws and releasing the clips.
3. Extract the Unit: Locate the white EWS box held by two bolts. Disconnect the connector and remove the module from the vehicle.

 

Step 2: Read IMMO Data (EEPROM)

To generate a key, you must read the data directly from the EWS3 chip.

1. Open the Module: Release the four plastic clips on the white casing to reveal the circuit board.
2. Prepare for Soldering: Clean the coating/glue off the specific pins on the chip to ensure a solid connection.
3. Wiring: Use the MCU Cable included with the Key Tool Plus. Follow the on-screen diagram to solder the colored wires (Red, Black, Yellow, Blue, etc.) to the back of the board.
4. Read & Save: Connect the cable to the Key Tool Plus. Select Prog -> IMMO -> BMW -> EWS3, then click Read and save the file.

Step 3: Generate the Dealer Key

1. Navigate to Immo Data Tool (Prepare Dealer Key) on the tablet.
2. Load the EWS3 file you just saved.
3. Select an “Unused” key slot (e.g., Key 10).
4. Insert a new Xhorse transponder or remote key into the Key Tool Plus coil and click Prepare Dealer Key.

Step 4: Decode & Cut the Key Blade

1. Decode the door lock using a Lishi HU92 2-in-1 tool.
2. Once you have the biting code, enter it directly into the Condor II database under BMW -> 3 Series -> HU92R ->Find Bitting for a factory-standard cut
3. Use the M5-B Clamp (position 2). Place the blank key, close the shield, and let the Dolphin automatically cut both sides.

Step 5: Final Synchronization & Remote Pairing

1. Reinstall the EWS3 module and reconnect the car battery.
2. Start the Engine: Insert the new key. If it doesn’t start on the first try, remove it and re-insert it to sync the rolling code.
3. Remote Programming:

• Turn the ignition to Step 1 (Accessory) and back off within 5 seconds; remove the key.
• Hold the Unlock button. While holding, press the Lock (Logo) button 3 times.
• The door locks will cycle to confirm success.
