How to Program a New Smart Key for the Wuling Confero (Hongguang S1) via LAUNCH X431

Published: June 2, 2026

Quick Answer

To program a new smart key for a Wuling Confero (Hongguang S1) using a LAUNCH X431, you need one working original key. Connect the X431 to the OBD-II port, select Wuling > Confero > Immobilizer > Key Learning, enter the 4-digit security code (found on the IMMO box behind the glovebox), validate the original key, then learn the new key. The process takes about 10 minutes and supports up to 4 keys.

Why This Procedure Matters

Losing your only smart key for a Wuling Confero—also sold as the Hongguang S1 or Baojun 730—can be a nightmare. Without a programmed spare, you’re looking at a tow to the dealership and a bill that often exceeds ₱5,000 (around $90 USD). The good news? The LAUNCH X431 diagnostic tool puts this capability in your own hands. It’s the same hardware many independent shops use, and with the right steps, you can program a new key yourself.

I’ve seen plenty of DIYers and even some mechanics get stuck on this procedure because they skip one critical detail: the security code. That four-digit number is your golden ticket, and knowing where to find it saves hours of frustration. Let me walk you through the entire process, including the tools you need and the mistakes to avoid.

Required Tools and Equipment

Before you start, gather everything on this list. Trust me—running to grab a missing tool mid-procedure is a headache you don’t need.

Tool / Item	Purpose
LAUNCH X431 (PAD V, V+, PRO3, or similar)	Performs IMMO key learning
Wuling Confero / Hongguang S1 (2015–2020)	Target vehicle
One working original smart key	Required for validation step
One or more new, unprogrammed smart keys	Must match the vehicle’s transponder type (4D-60 / ID44)
OBD-II cable (included with X431)	Connects tool to vehicle
Battery charger or jump pack (optional)	Prevents voltage drop during programming
5A fuse (optional)	Emergency power supply if OBD port fuses blow

Important: The new key must be a compatible blank. I recommend sourcing from a reputable seller who can verify it works with the Hongguang S1 platform. Cheap knockoffs often lack the correct transponder chip.

Step-by-Step Key Programming Procedure

Follow these steps in order. Rushing or skipping any step can lock your immobilizer for hours.

Step 1: Prepare the Vehicle and Tool

Make sure the car battery is fully charged—above 12.4 volts. A weak battery can cause communication failures mid-program.
Do not start the engine. Turn the ignition OFF.
Connect the LAUNCH X431 tablet to the OBD-II port located under the driver’s dashboard.
Power on the X431 and wait for it to boot. Ensure a stable Wi-Fi or mobile data connection—the tool needs to download vehicle-specific software during the initial scan.

Step 2: Enter the Vehicle Model

On the X431 home screen, tap Diagnosis.
Select SAIC-GM-Wuling (or simply Wuling depending on your region).
Choose Confero (or Hongguang S1—both are recognized).
Select the engine system: typically 1.5L or 1.8L.
If prompted for transmission type, pick Manual or Automatic based on your vehicle.

Pro tip: If the tool fails to find your model, try selecting Baojun 730 instead. These vehicles share the same platform and IMMO system.

Step 3: Access the Immobilizer (IMMO) Function

From the diagnostic menu, scroll down to Immobilizer or Anti-Theft System.
Select Special Function → IMMO Service.
Choose Key Learning or Program New Key.

The X431 will now prompt you for a 4-digit security code.

Step 4: Input the Security Code

This is where most people get stuck. The security code is unique to your car’s immobilizer box. Here’s how to find it:

Option A: Remove the glovebox (usually held by two screws). Behind it, locate a silver metal box with a white sticker. The code is printed on that sticker—four digits, often preceded by “CODE”.
Option B: If the sticker is missing or unreadable, use a paid online lookup service. LAUNCH offers a cloud-based IMMO database (requires credits), and third-party providers also exist. You’ll need your vehicle’s VIN.

Enter the code carefully on the X431 screen. Entering the wrong code three times locks the IMMO for 24 hours. If you’re unsure, double-check the sticker or pay for a verified lookup.

Step 5: Validate the Existing Key

Place your working original smart key in the ignition slot or hold it near the start button (depending on your model).
Turn the ignition ON (or press the start button once without your foot on the brake).
On the X431, tap OK. The tool will attempt to detect the original key.

If successful, you’ll see a message like “Original Key Detected”. If not, check that the key battery is good and the key’s transponder is intact.

Step 6: Learn the New Key(s)

The X431 will now display “Learning New Key”.
Insert the new, unprogrammed smart key into the ignition slot (or hold it against the start button).
Turn the ignition ON for 5 seconds, then OFF.
Wait for the X431 to confirm “Learning Successful”.

Repeat this step for each additional key you want to program. You can program up to 4 keys total. Remember: all keys—including your original—must be programmed in the same session because the process overwrites the existing key list.

Step 7: Verify and Exit

Remove the key from the ignition slot.
Press the start button (without the brake) to see if the dashboard light turns green or the steering lock releases.
Test remote functions—lock/unlock doors from a few feet away.
On the X431, select Exit, then turn the ignition OFF.

If the engine starts and the remote works, congratulations—you’ve successfully programmed a new smart key!

Troubleshooting Common X431 Programming Failures

Even with careful steps, things can go wrong. Here are the most common problems and how to fix them.

Error: “Communication Failure” or “No Response from IMMO”

Cause: Voltage drop during the procedure or a loose OBD-II connection.
Fix: Connect a battery charger in 10A mode to the vehicle. Turn ignition ON and re-scan the system. Also wiggle the OBD-II connector to ensure a snug fit.

Error: “Security Code Incorrect” (Tool shows 0 attempts remaining)

Cause: You entered the wrong code three times.
Fix: Do not disconnect the battery—it won’t reset the counter. You must leave the ignition ON for exactly 2 hours (engine off). After that, the IMMO will allow retries. Set a timer and wait; it’s the only fix.

Error: “This Vehicle is Not Supported” or “Function Unavailable”

Cause: Outdated X431 software or wrong vehicle selection.
Fix: Update the X431 software via Wi-Fi before starting. If the problem persists, try selecting SAIC-GM-Wuling → Baojun 730 instead of Confero.

Successful Programming but Key Does Not Start the Engine

Cause: The key blank lacks a transponder chip or is the wrong type. The Wuling Confero uses a 4D-60 (ID44) chip. Some cheap blanks from online marketplaces don’t come with a chip, or they use an incompatible format.
Fix: Test your blank with a transponder tester if available. Otherwise, buy from a supplier who guarantees compatibility with the Hongguang S1.

Frequently Asked Questions

Q: How many keys can I program for the Wuling Confero?

A: The system supports up to 4 keys total. You must program all available keys in one session; if you miss one, you must restart the process.

Q: Can I use a cheap blank key from online stores?

A: Yes, but ensure it has a 4D-60 transponder chip (also called ID44). Not all Chinese blanks work with the Hongguang S1. A proper blank from a reputable seller is recommended.

Q: Do I need to go to the dealer if I lost all keys?

A: Not always, but it is more complex. You can use the LAUNCH X431 to read the IMMO box EEPROM (requires soldering) or use a paid database to calculate the security code from the VIN. This is an advanced operation best left to experienced technicians.

Q: Will the programming process erase other keys already programmed?

A: Yes. The LAUNCH X431’s key learning function overwrites the existing key list. Always have your original keys ready, as you must program all keys (old and new) in the same session.

Q: Does the X431 need an internet connection to do IMMO?

A: Yes. The LAUNCH X431 requires a network connection to download the specific vehicle software and sometimes to verify the security code via cloud servers.

Q: My door locks don’t work after programming?

A: This is unrelated to the IMMO procedure. Check the remote key fob battery (CR2032). The key learning process only affects the engine immobilizer, not the central locking module.

Q: Is the procedure the same for the Wuling Hongguang S1 and the Confero?

A: Yes, they are the same vehicle sold under different names in different markets (Indonesia vs. China). The LAUNCH X431 should recognize both.
