Yanhua ACDP2 Supports Adding Xhorse and KYDZ 5C 5D Keys

In the past, Yanhua Mini ACDP Module 44 only supported adding new or used original factory MQB49 5C/5D keys, which limited key selection compared to other devices.

Good news: ACDP Module 44 has released a free software update on May 20th, 2026.
It now supports adding XHORSE VVDI and KYDZ 5C/5D keys.

 

New Functions:

• Write VVDI or KYDZ universal key (make dealer key by ICP mode)
• Modify VVDI or KYDZ 5C/5D key ID.

Which Xhorse VVDI key can be used for MQB49 5C/5D system?

For MQB49 5C system:

Xhorse VVDI smart key (NXP, XM38, XM38 Toyota, XSMQB all ok).

For MQB49 5D system:

Xhorse 5D key (not available yet) or VVDI BMW F/G chassis smart keys.

 

Note: Keydiy KD keys have been program-encrypted by the manufacturer and cannot be used with ACDP devices.

EoneBoss NK001 Copy Smart Key with Solder Free Adapter

In our previous post, we demonstrated how to copy an NCF29Ax smart key with EoneBoss NK001 using the wire-soldering method; today, we will introduce an alternative approach—one that does not require soldering wires.

 

Key type example: Hyundai ID47 smart key.

Method: solder free with interface board.

 

Procedure:

Download and run the EoneBoss NK001 App.
Choose Smart Key Copy Function.
Read instructions and confirm.
Write the identified original smart key information into an original or 3rd party key. It can be used directly without programming afterwards.

*NCF29AG is not supported. Some 3rd party keys may have incorrect button functions.

You need to open the original key shell and take out the circuit board.

2 Ways to connect the key circuit board with NK001.
Way 1: Use NK001 connector adapter
Way 2: Use solder free interface board.

NK001 will show key wiring diagram.

The App shows NCF29A diagram at present. They will release more diagrams in PDF format.

Connect key board with NK001 via the solder adapter according to the diagram.

Here we will introduce way 2.

Connect the solder-free adapter with NK001 via USB cale.


It has a PIN15 probe (purple), this probe needs to connect to key board.

Click Next step.

Press the NK001 button for 3 seconds to power on and enable your Phone’s bluetooth.
Connect NK001 with Bluetooth.

Click Connect.

Read original key information.

Read original key information successfully. NK001 will read key chip type and ID.

Prepare the smart key to be copied.

Install the new key board to the interface board and connect with NK001.

Click Copy function.

Copying key in process. Do not remove the key or probe during this procedure.

Generate a new smart key successfully. Don’t need to program this new key afterwards.

If your key is an Eoneboss smart key, there is no daily generation limitation.
If it is other keys, you can generate up to 5 keys each day.

EoneBoss NK001 vs HK001 Device

Question: What’s the difference between EoneBoss NK001 and HK001 key copy device? They all copy Hyundai /Kia NCF29Ax smart keys?

Here is the clue.

1. Vehicle Coverage 

HK001: for Hyundai and Kia only

NK001: for multile brands

 

2. Functions

HK001:

1). Generate Hyundai Kia smart remote

2). Copy Hyundai/Kia NCF29Ax smart key.

3). Unlock Hyundai/Kia smart keys

HK001:

Copy NCF29Ax smart keys for multiple car brands.

Both devices will copy Hyundai/Kia NCF29Ax smart keys. HK001 will do Hyundai/Kia only. NK001 cannot generate remote and unlock smart key. It only copy smart keys.

How to Open 2021+ Buick GL8 Smart Key Shell?

How to remove and disassemble the shark fin style key shell of a Buick 4A smart key?

Vehicle models: Buick GL8, Envision, etc.

 

Purpose: Battery replacement or key repair (water-damaged).

How to disassemble key shell?

Press the button on the side of the key and pull out the mechanical key.

Remove the top cover of the key.

Use a utility knife or flathead screwdriver blade to carefully separate the ultrasonically welded inner shell of the key.

Exercise extreme caution when prying open the inner shell.

Once opened, you will see the coin cell battery. Battery model: CR2450.

In this particular case, the original key had been water-damaged. After removing the key circuit board, no frequency could be detected.

A Xhorse digital multimeter test revealed a leakage current issue on the board.

After repairing the key, current draw was measured and found to be within normal limits, and frequency detection was successfully restored. Key repair completed.

Keydiy KD-X2 detects key frequency.

How to Program 2024 Honda Prologue Smart Key with SPS2

What device to program 2024 and onwards Honda Prologue proximity smart key?
Does Honda i-HDS program this key?
It looks like GM remote.

Here is the clue.

The Honda Prologue & Acura ZDX were developed on a GM Ultium platform, standard Honda diagnostic tools (like i-HDS) do not work for their module programming.

These vehicles (Prologue EV and ZDX) are actually GM-built. And it appears that GM dictated that SPS2 would be the only programming tool to touch them. It is an EV Blazer rebadged.

SPS2 all day long on the Prologue EVs.

What you need:

• A Windows PC
• A validated J2534 passthrough device (such as the GM MDI-2/Topdon Rlink J2534/VXDIAG VCX CAN FD)
• An active SPS2/Techline Connect subscription.
• Battery tender on the 12V battery – Essential to prevent voltage drops during programming.
• EV charger connected – Keeps the high-voltage system stable.
• Laptop with internet connection – First-time software downloads can take over an hour.

You will see manual selection under SPS2 for make and see Acura and Honda.

What it does:

SPS2 is used to flash, configure, and update electronic control units (ECUs), infotainment systems, and perform key/immobilizer programming.

 

How to Program 2024 Honda Prologue/ Acura ZDX Smart Key with Techline Connect SPS2?

How to set up GM TLC SPS2 for these EVs?

 

Step 1: Prepare the Vehicle

Put the Honda Prologue into service mode by holding the start button for about 10 seconds until the vehicle enters accessory mode. This keeps the electronics awake without starting the propulsion system.

Do not skip the battery tender and charger. Programming failures often happen due to voltage drops.

 

Step 2: Log Into Techline Connect (TLC)

Open your browser and log into your ACDelco TLC account. If you don’t have a subscription yet, you can purchase one per VIN—typically around $35–$45. Once logged in:

• Click Add VIN and enter the Prologue’s 17-digit VIN.

• The system will launch the SPS (Service Programming System) application.

• If it’s your first time, be patient—initial software downloads can take 1 to 1.5 hours, especially after adding Honda/Acura patches.

Step 3: Connect to the Vehicle

Once SPS is open:

• Click Connect Vehicle.

• The system will recognize the VIN (e.g., 2024 Honda Prologue Touring).

• If the vehicle doesn’t appear automatically, go to the SPS tab and select Reprogram.

Chip notes that the first connection to a new vehicle can take up to 5 minutes while the tool communicates with all controllers.

 

Step 4: Select the Module to Reprogram

After the connection is established, you’ll see a list of Supported Controllers. This includes:

• Radio (infotainment)

• Immobilizer (key programming)

• Body Control Module (BCM)

• And more

To program a new key, select Immobilizer Learn and choose the appropriate option (e.g., “Add a Key”).

To reprogram the radio, select the radio module. The system will guide you through preparing a USB drive, transferring files, and then plugging that USB into the vehicle’s port to complete the flash.

Step 5: Follow the On-Screen Prompts

• The software may warn you that you’re reprogramming with the same calibrations. You can override this if needed.

• Programming time varies.

If a module fails to reprogram, it may be physically faulty.

 

Important Limitations

• SPS is for reprogramming only – It is not a diagnostic tool. You’ll need separate GM diagnostic software or hardware for advanced troubleshooting.

• Honda Prologue requires GM tools – Due to the shared platform, you cannot use Honda’s standard HDS system for low-level module programming.

• Key programming is possible – You don’t need special access. Just a proper replacement key and the immobilizer learn procedure.
