Xtool Program VW Passat CC 2014 ID48 All Keys Lost

 In this guide, we’ll walk through the process of creating a dealer key using the XTOOL IP900/D9/X100 PAD3 etc and KC501 programmer. This method involves reading the ID48 chip from the vehicle’s EPROM (95C320) to extract the necessary data for programming a new key.

 

Tools Required

1. XTOOL IP900/D9/A80/X100 PAD3 etc (with KC501 adapter).
2. Soldering equipment (hot air station, flux, soldering iron).
3. EPROM reader (compatible with 95C320 chip).
4. New ID48 transponder chip (for dealer key).
5. Magnifying tool (for identifying chip pins).

 

 

Step 1: Locate and Remove the EPROM Chip

1. Access the ECU: Open the vehicle’s immobilizer unit to locate the 95C320 EPROM chip.
2. Identify Pin 1: Look for the small white dot or marking on the chip (bottom left corner). This indicates Pin 1, crucial for proper alignment.
3. Desolder the Chip:
   • Apply flux around the chip to ease removal.
   • Use a hot air station (set to ~400°C) to gently heat the chip’s edges until it lifts off.

Step 2: Read the EPROM Data

1. Connect the Chip: Place the desoldered chip into the EPROM adapter, ensuring Pin 1 aligns correctly.
2. Use XTOOL KC501:
   • Navigate to Special Functions > EPROM > ST 95C320.
   • Select “Read Data” to extract the immobilizer information.
   • Save the data.

Step 3: Extract the PIN Code

1. Open XTOOL IP900:
   • Select IMMO Reset- Volkswagen > Passat CC (2008–2017).
   • Choose “Get CS Code” and load the saved EPROM file.
   • The tool will automatically display the 4-digit PIN code (required for key programming).

Step 4: Program the New Key

1. Prepare the Key:
   • Place a new ID48 transponder in the key programming coil (connected to the KC501).
2. Start Programming:
   • Select “Make Dealer Key” and enter the extracted PIN code.
   • Follow on-screen prompts to complete the process.
3. Verification:
   • The tool will confirm “Success” once the key is programmed.

Final Steps

• Reinstall the EPROM: Solder the chip back onto the ECU (if needed).
• Test the Key:
  • Start the vehicle to ensure the new key is recognized.
  • Verify remote functions (lock/unlock).

Program VW Golf NEC23C32 All Keys Lost with Xtool and KC501

In this tutorial, we’ll walk through the process of programming a Volkswagen Golf 5 key, including making a dealer key and performing bench learning using the Xtool IP900 (or D9, X100 PAD3 etc with KC501). 

Tools Used

• Xtool IP900 (or other Xtool key programming tool)

• VVDI Super Chip 

• KC501 programmer

• GoDiag GT110 test platform (For ignition simulation on the bench)

Step-by-Step Process

1. Setting Up the Bench Test

• The instrument cluster is powered at 11.7V to simulate the car’s ignition.

• The GoDiag GT110 is used to control the ignition state (on/off).

2. Selecting the Vehicle in Xtool IP900

• Navigate to Special Functions > Immobilizer.

• Choose Volkswagen > Golf (1K, up to 2014).

• Select the NEC+ 24C32 immobilizer type.

3. Reading the EEPROM Data

• The tool prompts to turn the ignition on (simulated via the bench setup).

• The EEPROM data is successfully read and saved.

4. Making a Dealer Key

• The Xtool IP900 requires the KC501 adapter.

• A VVDI Super Chip is placed in the adapter and converted to a 48-chip (VW-specific transponder).

• The tool confirms the chip is successfully programmed as a locked, clonable dealer key.

5. Key Learning Process

• Unlike other tools (e.g., IM508), the Xtool IP900 does not require entering a PIN or CS code, making the process faster.

• The key is learned successfully, and the transponder data is verified again using the VVDI tool to confirm cloning compatibility.

6. Cloning the Key

• A second VVDI Super Chip is converted to a 48-chip.

• The cloned key is created and verified—both keys now have identical transponder data.

Comparison: Xtool IP900 vs. IM508

Feature	Xtool IP900	IM508
Speed	Faster, no PIN/CS needed	Slower, requires PIN
Ease of Use	Simple, intuitive interface	More steps involved
Cost	More affordable	More expensive
Adapter Support	Works best with KC501	Compatible with multiple adapters

Conclusion

The Xtool proves to be an efficient and cost-effective solution for VW Golf 5 key cloning, offering a streamlined process compared to higher-end tools like the IM508. Its no-PIN learning and quick transponder conversion make it a preferred choice for locksmiths and automotive technicians.

Final Thoughts

• Pros: Fast, affordable, user-friendly.

• Cons: Limited adapter flexibility (KC501 required).
