Learn how to quickly synchronize and clone original key data using the KEYDIY KD-X4, 13# Remote Chip Reading Adapter, and C29AX71 Smart Key. This method enables seamless key addition without complex on-board programming, making it ideal for water-damaged keys or vehicles with difficult learning procedures.

Thechip synchronization now supports the NCF29AX series, including NCF29A1, NCF29A4, NCF29A2, NCF2953, NCF29A3and NCF2954.

Required Tools & Preparation Ensure the following hardware and software are ready before proceeding: Main Devices: KEYDIY KDX4 or KD MAX. Specialized Key: KEYDIY C29AX71 Smart Key. Adapter: KEYDIY 13# Remote Chip Reading Adapter. Software: Update your KD App to the latest version before proceeding.

Note: This is not a simple read-and-copy procedure; some keys require chip removal and soldering. There is no need to generate a remote program before reading the original key data.

Step-by-Step Synchronization Guide 1. Extract the Original Chip Disassemble the original vehicle smart key and carefully remove the NCF29AX series chip.

2. Attach the Chip to the #13 Adapter Solder the chip onto the 13# Adapter and connect it to your KD-X4 or KD-MAX. Alternative Method: Follow the provided wiring diagram to solder wires directly to the keyboard to read and save data without removing the chip.

3. Synchronize via KD App Navigate to: Remote function >> Smart key clone >> Universal smart key synchronization>> Read Chip data. This process syncs the original chip’s remote data and key ID to the CAX and CA7 series.

4. Write to C29AX71 Smart Key ① Connect C29AX71 Smart Key to the KD-X4 using the 6-pin programming cable. ② Select "Generate dealer keys". ③ Once finished, snap the key shell onto the new hardware.

Final Results & Advantages The primary advantage of this method is efficiency. After writing the data, the new key works directly on the vehicle with no additional programming required. Always test both the new C29AX71 Smart Key and the original key to confirm all functions operate normally.

Looking for a reliable way to program the latest Volkswagen and Audi 5D immobilizer systems? The KEYDIY KD-X4 and the new FGB-series PCBs provide a professional-grade solution for automotive locksmiths. This guide covers the seamless programming process for the FGB08 (Audi Waterdrop design) and FGB25 (VW Golf 8 design) keys.

Hardware Essentials KEYDIY KD X4 Key Programmer: The core 5-in-1 programming device. KEYDIY FGB08/FGB25 PCB: Specialized keys supporting VW 5D and compatible Audi models. Original Vehicle Key: Required for data reading and service code generation. Note on FGB Keys: Out of the box, only the last button on a new FGB key will emit a frequency. All buttons activate automatically once programming is complete.

Step-by-Step Programming Guide 1. Vehicle Data Acquisition Connect your KD-X4 to the vehicle and access the IMMO menu: (1) Navigate to: Immo programming > Volkswagen > 5C/5D immobilizer system. (2) Select Start execution > Read vehicle information. (3) Place the original key in the vehicle's ignition area (e.g., the cup holder) and turn on the ignition. (4) Record the Key IDs and ensure you have the KD Service Code generated from the original key data.

2. Generate the Dealer Key Prepare the new KEYDIY FGB remote to be recognized by the vehicle: (1) Select Read original car key and generate a dealer key. (2) Place the new FGB key on the KD-X4 induction area. (3) Select KD-FGB remote (wireless) and the correct frequency (433.46/434.36MHz) to write the data.

3. Key ID Synchronization (Cloning) To ensure perfect compatibility, write the original key's ID to the new remote: (1) Go to Chip Function > Automation detection clone > Chip editing. (2) Enter the original vehicle ID (e.g., 35A8F4B0) and click Write.

4. Final Key Learning Complete the process by syncing all keys to the immobilizer: (1) Return to 5C/5D immobilizer system > Key learning. (2) Enter the total number of keys to be learned and confirm they are smart keys. (3) Follow the prompts to place each key (original and new) on the vehicle's induction coil one by one. (4) Once "Matching successful" appears, cycle the ignition to finalize the sync.

Why Choose KEYDIY for 5D Systems? The KEYDIY KD-X4 simplifies complex 5D programming into a user-friendly workflow. With the FGB08 and FGB25 keys, you can offer customers high-quality replacements for modern Audi and VW Golf 8 models with confidence.

Problem Background: The KEYDIY KD-MP Tool typically reads original MLB keys without issues. However, users may encounter a specific failure during MQB48 data collection: the tool successfully reads the Key ID and begins the server upload process, but then terminates with a "Server self-check failed" error.

This usually indicates a synchronization issue between the local hardware reading and the server-side validation, rather than a standard network outage.

1. Verify Software Version (Crucial) The most common cause for this error is outdated firmware or software. KEYDIY frequently releases patches to fix key-reading bugs. Current Stable Version: V1.8.7 (Released Feb. 2026) or later. Action: Ensure your KD-MP software is fully updated. This version specifically addresses MQB48 data collection stability.

2. Hardware & Wiring Inspection If the software is up to date but the error persists after the tool reads the Key ID and uploads it to the server, check the physical connection: Solder Points: Inspect the board for cold solder joints. Whether you are using pogo pins or soldering wires directly, ensure all points are securely re-soldered according to the official pinout. Wiring Accuracy: Cross-reference your physical connections with the official KEYDIY wiring diagram for the specific MQB48 module you are servicing.

3. Signal Interference & Positioning Environmental factors can disrupt the high-frequency data collection required for MQB48. Adjust Positioning: Change the position of the board or the KD-MP unit to exclude electromagnetic interference. Environmental Check: Move the setup away from high-power electronic devices (such as WiFi routers or induction heaters) and large metal workbenches that may shield the signal.

Summary Checklist

Note: If the "Server Self-Check Failed" error persists after completing all the steps above, please contact KEYDIY Customer Service for further technical support.

Here are some frequently asked questions about KEYDIY, including real name authentication, KD-coins, and function activation.

This guide applies to KEYDIY KD-X4, KD-MAX, etc.

Q1: What is real name authentication and why is it required?

A: Real name authentication is a mandatory process designed for improved account management and security.

The system identifies you and retrieves your binding information using your mobile phone number.

After logging in, you must complete this authentication before proceeding.

Q2: How do I complete real name authentication?

A: Follow these steps:

Fill in the three required fields: you may enter any name or random text as needed.

Select your region (e.g., China) and enter your mobile phone number.

If you don’t receive a verification code, enter the universal code: 200909.

The optional field can be left blank. Submit the form, then wait 2–3 minutes for automatic backend approval. Once verified, you will receive 50 KD coins as a reward.

Q3: How can I obtainKEYDIY KD-coins?

A: KD coins can only be earned by generating new keys with a KD device. They are not available through direct purchase or other means.

Q4: How do I recharge my wallet balance?

A: Currently, only Android devices support recharge via Google account. iPhone users cannot recharge at this time.

Q5: What if I don’t have enough KD coins or dollars to activate a function?

A: If a function requires payment (e.g., 2500 KD coins or $75) and you lack sufficient balance, you can ask someone else to activate it for you. This could be your dealer, a local locksmith, or a friend who uses the same system.

Q6: How can someone activate a function on my behalf?

A: The helper should:

Open the app, go to More > Activate License on Behalf.

Click “Select User”, enter your registered mobile phone number (e.g., 15932047924) to locate your account.

Select the function(s) to activate (e.g., MQB, BMW) and choose payment via KD coins or dollars.

Complete the payment; once successful, the function will be activated on your account.

Q7: Can KEYDIY KD coins be transferred between accounts?

A: Yes. To transfer KD coins:

Select My KD-coins-> KD-coins Transfer

Enter the recipient’s phone number

Specify the amount (e.g., 100 KD coins) and click “Transfer”

The coins will be deducted from your balance and credited to their account.
