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).
