Comprehensive Guide to Programming VW GEN4 NEC24C64 Keys Using OBDSTAR X300 Classic G3

In the world of automotive diagnostics and key programming, the OBDSTAR X300 Classic G3 stands out as a reliable tool for professionals and DIY enthusiasts alike. This article provides a detailed, step-by-step guide on how to use the OBDSTAR X300 Classic G3 along with the VW4-AKL cable to program VW GEN4 NEC24C64 keys on the bench, particularly when all keys are lost.

Understanding the OBDSTAR X300 Classic G3

The OBDSTAR X300 Classic G3 is an advanced diagnostic scanner designed for a variety of vehicles, offering functions like key programming, IMMO services, and more. Its compatibility with VW, AUDI, SKODA, and SEAT makes it a versatile tool for automotive technicians. Before beginning any programming, ensure that the software is updated to V45.51 or above to access the latest functionalities.

Preparation for Key Programming

Before diving into the programming steps, ensure that you have the following items ready:

• OBDSTAR X300 Classic G3 device
• VW4-AKL cable
• Power supply for the vehicle dashboard
• Internet connection (to connect to the server)

Step 1: Backup EEPROM Data

The first crucial step in programming a new key is to back up the EEPROM data. This ensures that you have a copy of the original data in case something goes wrong during the programming process.

Follow these steps:

1. Connect the OBDSTAR VW4-AKL cable to the main cable and plug it into the vehicle's dashboard.
2. Power the dashboard on.
3. Select IMMO from the main menu.
4. Choose VW/AUDI/SKODA/SEAT from the options.
5. Select the Latest Version and then Manual Select System.
6. Choose VW and select 4 GENERATION CAN METER.
7. Click on AUTO DETECT and then OK.
8. Choose All Keys Lost to read IMMO data directly via the VW4-AKL cable.
9. Tap on OK and select Read EEPROM.

Follow the on-screen instructions carefully. If you plan to program keys in Bench mode, consider purchasing an additional induction coil as per the operational guide.

Installing the Induction Coil

If you need to install the induction coil, follow these steps:

1. Power off the device.
2. Remove the plug and locate pins 7 and 8 based on the prompts.
3. Insert the pins correctly, then reset the system.
4. Tap [Pinout] to view the wiring diagram and find an image that matches your dashboard type.
5. If you can't find an exact match, use the first general diagram to identify the correct points.
6. Power off again, place the probe on the identified point, and turn on the power.
7. Wait for 6-7 seconds until the dashboard emits a sound, then tap [Enter] to confirm.

Once the EEPROM data is backed up successfully, you can proceed to the next step.

Step 2: Read IMMO Data

Reading the IMMO data is essential for verifying the vehicle's security features.

1. Select Read IMMO Data from the menu and click OK.
2. Follow the same steps as before: power off, place the probe, power on, and wait for the sound.
3. After the sound, remove the probe.

If done correctly, you should see a message indicating that the IMMO data has been read successfully.

Step 3: Program the Key

Now it’s time to program the new key. Ensure you have the dealer key ready for programming.

1. Place the key inside the X300 Classic G3 induction coil.
2. Select the option to make a dealer key.
3. Once the key is detected, follow the device prompts to program the key.
4. Keep the key close to the coil until the device indicates that the programming process is successful.
5. Check the IMMO status again to confirm that the key is now programmed.

Once the programming is complete, test the key in the vehicle to ensure it works correctly.

Conclusion

Programming keys for VW GEN4 NEC24C64 models using the OBDSTAR X300 Classic G3 is a straightforward process when following the right steps. Always remember to back up EEPROM data and read IMMO data before programming to avoid any complications. With the right tools and a little patience, you can successfully program new keys and maintain the functionality of your vehicle's security system. For further assistance, don’t hesitate to consult the device manual or seek expert advice.

Happy programming!
