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.

How to Copy 2021 Havel H6 ID47 Smart Key with Keydiy KD-X4?

Keydiy KD-X4 has recently updated the NXP NCF29Ax smart key copying function. Here, we will demonstrate how to copy a 2021 Haval H6 smart key using KD-X4.

 

Chip type: ID47

Original key type: NXP29A1

Tools used:

Keydiy KD-X4 key programmer

Keydiy NCF29xx adapter (#13 adapter)

Keydiy KD C29A71 smart key

Original smart key

A hot gun

Anti-static tweezer

 

Advantages of this method:

• The key copied KD smart key features smart functions.
• If the original vehicle has door handle sensor (keyless entry), the key will still detect and unlock via proximity.
• For some vehicles that require a security code for pairing, this method is cost-effective.

Disadvantages:

• The C29 key has no remote control buttons.

 

Procedure:

Disassemble the original smart key shell and take out the circuit board.

Locate NXP29xx processor chip. Here it is NXP29A1 chip.

Desolder the NXP29A1 chip.

Solder the NXP chip onto the Keydiy NCF29xx adapter with a hot gun.

Connect the NCF29XX adapter with KD-X4 main unit.

In KD app, go to Remote Function-Smart Key Clone- Universal smart key synchronization.

Check the wiring diagram, here we use KD NCF29xx adapter without soldering wires.

Select Read Chip data.

Read original key chip data.

Enter vehicle model, year and FCCID to save key chip data.

Write smart and proximity sensor to the new KD key.

Connect the KD C29A71 key circuit board with KD-X4 using the 6 pin programming cable.

Generate proximity key successfully.

Then install the KD circuit board with key shell.

Reinstall the key chip back onto the original key circuit board. Install the original key shell.

Don’t need to program key in car afterwards.

Test both keys.

The new key is ready to use.

Done.

EoneBoss TLK3 Generate Toyota All Keys Lost Remote Guide

 

EoneBoss TLK3 Toyota smart key unlock & generation device released a major update in May 2026- All keys lost smart key generation.

 

Supports Toyota and Lexus smart key models.
Without the original car key. It can identify car key, type, frequency and frequency sequence of the smart key used in the car based on the signal from the ignition switch inside the car. It can directly generate an ET sub-unit based on the identified content or serve as a reference when using other devices.

Suppor type:

4D (94, D4, 98, 9F, 78, F1)
8A (39, 8, A9, A8, AA, B8,BA, F3, F4)
It will make a 4A chip type in the feature.
Here we will show how to perform all keys lost smart key generation using TLK3.

Model example: 2025 Lexus ES200
Chip type: 8A B8

Charge the TLK3 device for 1 hour.
Download or update EoneBoss App to the latest version.
Run EoneBoss App.
Choose TLK3 device.

Start scanning the TLK device.
Press the blue round button on the TLK3 unit for 3 seconds to connect the TLK3 via Bluetooth.

Choose All Keys Lost Generation function.

TLK3 will collect the data from the vehicle from the ignition switch.
You need to press the Start-Stop button when you collect the data.
Once you get the key information, you can generate Eoneboss ET smart key or generae other brand keys.
No daily use limitation for EonBoss ET smart key.
Do not have any smart of other cars inside the car and support types.

Click Confirm.

Put your TLK3 near the start button.
Press the start nutton every 5 seconds until the information is obtained.

Select Toyota or Lexus brand.

This time you need to place the TLK3 near the gear lever and pres the start button every 5 seconds unilt the message is obtained.
The PKE antenna location may be different on different models. Change the TLK3 at differnce place.
You need to put the TLK near the PKE antenna.

It will show chip type, frequency and the correct frequency sequence.
Once you get the key information, you can generate ET smart key or you can generate other brand key.

NOTE: Program smart key with other OBD programers in car after generating smart key.
