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 35–35–45. 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:
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
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.
