Whether you are using X300 Classic G3 (KeyMaster G3) or X300 PRO4 (Key Master 5), this harness has got you covered.

Let’s dive into how this neat tool works and how to get your new key programmed in minutes.

The Walkthrough: Programming Your NIO Key
What You Need:
• OBDSTAR X300 Classic G3 tablet & main cable
• OBDSTAR C1031 NIO Gateway Harness
• A new blank key

Let’s Get to Work:
Step 1: Hooking Up the Hardware
• Pop off the cover under the steering column.
• Unplug the connector you see underneath, and bridge it using your C1031 dedicated harness.
• Now, plug the harness into the car’s diagnostic port, and connect the other end straight into your KeyMaster G3 main cable. Wiring is officially done!

Step 2: Finding the Vehicle on Your Tablet
• On your OBDSTAR screen, tap IMMO and type NIO in the search bar.
• Go to NIO -> [Latest Software Version] -> Manual detect model -> EC6 -> Proximity -> 2019–2022 -> Key count.
• You’ll see the current key count is 0, and the new key won’t start the car just yet.

Step 3: Programming the Smart Key
• Go back one step and hit Program keys.
• Make sure the car is safely in Park (P) and turn off the wireless phone charger (this prevents signal interference!).

• Place your new smart key into the car’s key-sensing spot inside the center console armrest box, then hit OK.

Step 4: Test & Go!
• Success! The screen will update, showing the key count is now 1.

• Step outside the car and test the remote lock/unlock and ignition functions. Everything is perfectly programmed!

EoneBoss HK001 Guide: Unlock Used Hyundai & Kia NXP Smart Keys

 Locked secondhand keys are a common headache for automotive locksmiths. If you want to reuse an OEM remote, EoneBoss HK001 Key Master offers an efficient solution for renewing used Hyundai and Kia NXP (NCF29Ax) smart keys.

Using a Hyundai 4A AES smart key as our example, this walkthrough covers the step-by-step process of using the hardware alongside its mobile application to restore the key to factory settings.

Step-by-Step Bench Reset Procedure

Before opening the tool, install EoneBoss app on your mobile device and place your hardware nearby.

Select the Remote Casing Style

• Open the mobile application and tap through: HK001 -> Used Smart Key Unlock.

• Scroll through the gallery and pick the key casing silhouette that matches the remote in your hand. The brand emblem and button configuration do not matter here — just match the physical shape of the shell. (NCF29AG is not supported yet!)

Identify the Circuit Board Layout

• Disassemble the remote shell and extract the internal printed circuit board (PCB).
• Examine the components on the board to select the matching hardware configuration and NXP chip model within the app interface.

Review the Pinout Diagram

• The application will display an exact wiring schematic for your specific board.
• Attach the required jumper leads from the key board terminals to the programmer pins based on the illustration. (Note: Solder-free connection adapters will be released in the future, but standard wiring pinouts must be used for now).

Pair Your Phone via Bluetooth

• Hold down the power button on HK001 unit for 3 seconds to boot up the hardware.
• Enable Bluetooth on your smartphone.
• Let the app scan for nearby hardware, then tap Connect to establish the wireless link.

Read and Clear the Transponder Data

• EoneBoss HK001 will automatically analyze the connected PCB to display its chip variant, unique Key ID, and original factory part number.

• Verify the data and tap the Unlock button.
• Crucial: Leave the hardware completely still and do not interrupt the power supply while the clearing process runs.

Once the notification confirms a successful reset, the transponder is fully unlocked and ready to be programmed to another vehicle!

Essential Usage Rules & Hardware Limits

To avoid workflow interruptions on your bench, keep these manufacturer rules in mind:

• Unlimited Unlocking: There are absolutely no daily restrictions or token costs when resetting original Hyundai/Kia NXP proximity keys.
• Copy Limits: If you are cloning data onto non-EoneBoss aftermarket NCF29Ax transponders, the software enforces a limit of 5 keys per day. Cloning data onto official EoneBoss remotes remains completely unlimited.
• Unsupported Architecture: The next-generation NCF29AG chipsets cannot be processed by this tool yet.
• Working with 8A Systems? HK001 hardware is dedicated strictly to NXP transponder types. If you need to clear a Hyundai or Kia 8A smart key (Texas Instruments / TI chip), you must use EoneBoss KH002 programmer instead.

EoneBoss HK002: Hyundai & Kia 8A Key Unlock (No Disassembly)

 Working with newer Hyundai and Kia 8A smart keys often involves extra wiring, key disassembly, and unnecessary risk during preparation. The EoneBoss HK002 simplifies this workflow by enabling non-destructive unlocking and built-in PIN code reading for supported TI-based 8A smart keys. It reduces preparation steps and helps technicians move faster from key access to programming.

Key Advantages for Daily Locksmith Work

Non-Destructive Key Unlocking

• No shell opening required
• No soldering or wiring connection
• Preserves original key condition
• Reduces handling risk during preparation
• Ready for programming after unlock

Built-In PIN Code Retrieval

• Reads supported PIN codes directly from smart keys
• Identifies key information and part numbers automatically
• Reduces dependency on external PIN lookup services
• Minimizes additional operational cost and delays

Designed for Modern 8A Platforms

• Supports Hyundai & Kia 8A smart keys with TI chips
• Built for newer-generation smart key systems
• Streamlines workflows that traditionally require multiple tools or steps

Fast Key Identification Process

• Detects key status, chip type, and chip ID
• Provides key data before unlocking
• Helps confirm compatibility before programming

HK002 vs HK001 Comparison

OBDSTAR VGS4 Gearbox Cable Guide for Benz FBS4

 Some customers reported that OBDSTAR C4–08 Adapter Kit is out of stock. OBDSTAR has updated and modified its VGS4 TCU software functions and menus, eliminating the need for that specific adapter.

Instead, depending on whether you are working in Bench or Jtag mode, you will use alternative cables and setups:

For VGS4–500-NAG2 Gearbox

• Bench Mode: Instead of the old adapter, use OBDSTAR TCM-014 bench fast cable. This allows you to perform Read Data, Data Transfer (Personalization), and Write VIN functions.
• Jtag Mode: Simply use W013 cable. Devices like OBDSTAR G3 or DC706 will provide the correct wiring diagram directly on-screen. In Jtag mode, you can perform Read Data, Virgin (Renew), Data Transfer (Personalization), and Write VIN functions.

For VGS4–0-NAG2 Gearbox (Alternative)

If you ever need to work on the VGS4–0-NAG2 variant, the updated requirements are:

• Bench Mode: Use OBDSTAR TCM-012 Connector for a no-soldering solution to reset/virginize the TCU via OBD or Bench.

• Jtag Mode: Use C4–07 adapter kit if you need to transfer VGS4 data.

Summary of Compatible Tools for VGS4

If you are looking for alternative hardware tools that support VGS4 functionality, the following tools are confirmed or noted in the industry:

• OBDSTAR DC706 (Confirmed)
• Autel IM508S / IM608 PRO II (Recently updated/confirmed)
• LAUNCH X431 X-PROG3 (Confirmed)
