How to Program a Smart Key on a GAC Trumpchi Empow (2022–2024) Using LAUNCH X431

Published: June 16, 2026

Quick Answer

To program a smart key on a 2022–2024 GAC Trumpchi Empow using the LAUNCH X431, connect the scan tool to the OBDII port, navigate to the Anti-Theft System, select Key Programming, enter the security access code (commonly 123456), and follow on-screen prompts to match up to two new keys. You need at least one working master key, and the entire process takes about 10–15 minutes.

Why You Might Need to Program a Smart Key on a GAC Trumpchi Empow

Losing or damaging a smart key is never convenient. The GAC Trumpchi Empow—a modern compact sedan with push-button start—relies on a transponder-based smart key system that communicates with the vehicle’s immobilizer. If you've lost your only key, bought a used Empow that came with just one key, or need to add a second fob for a family member, you have two options: a costly trip to the dealership or a do-it-yourself approach using a professional-grade diagnostic tool like the LAUNCH X431.

The LAUNCH X431 series (including models like the X431 V, PAD, and PRO5) gives independent mechanics and advanced DIYers the ability to perform dealer-level functions—including smart key programming—without the need for specialized factory equipment. In this guide, I'll walk you through the exact process, share common pitfalls I've seen over the years, and explain how to recover if something goes wrong.

What You’ll Need Before You Start

Required Tools and Materials

Important Warnings

• The LAUNCH X431 must have an active internet connection before you start, especially if you need to download the GAC Trumpchi software package or use the automatic security code retrieval.
• Low smart key batteries can prevent successful programming. Replace the coin cell in each fob (typically a CR2032) before you begin.
• If the vehicle battery voltage drops below 12.4V during programming, the tool may lose communication. I always recommend using a battery maintainer or jump pack connected to the vehicle’s battery terminals if the engine isn’t running.
• For 2024 model-year vehicles, make sure your X431 firmware is up-to-date—GAC occasionally updates immobilizer protocols, and an outdated scan tool may fail to communicate.

Step-by-Step: How to Program a Smart Key on a GAC Trumpchi Empow

Step 1: Connect and Launch the LAUNCH X431

1. Physically connect the tool: Plug the X431 main cable into the vehicle’s OBDII port, located under the dashboard near the steering column. Turn the ignition to the ON position (engine off). The X431 should power on automatically.
2. Select the vehicle: On the tool’s home screen, tap Diagnosis → AutoVIN. The X431 will automatically read the VIN and suggest the correct make and model. Alternatively, you can manually select GAC Trumpchi → Empow → 2022–2024.
3. Wait for system scan: The tool will scan the vehicle’s control modules. This may take 30–60 seconds. If you see a message like "communication failure," check the OBDII connection and battery voltage first.

Pro tip: If AutoVIN fails, try manually entering the last 8 digits of the VIN. Some 2024 models have been known to cause issues if the X431’s database isn’t fully updated.

Step 2: Navigate to the Key Programming Menu

Once the vehicle is identified, you’ll see a list of available systems. Follow this path:

• Body Control Module (BCM) — or, depending on the X431 software version, look for Immobilizer System
• Anti-Theft System (sometimes listed as Immobilizer)
• Key Programming (or Smart Key Function)

Some X431 models present a direct shortcut called Smart Key Programming under the main menu. If you see that, select it directly.

Step 3: Enter the Security Access Code

The immobilizer requires a security code before it allows key programming. Here’s what you need to know:

• If you have a working master key, the X431 will usually prompt you to either enter the code manually or retrieve it automatically via an online service.
• Common factory codes for GAC Trumpchi vehicles are 123456 or 1234. Try these first if you don't know the code.
• Automatic code retrieval: Select the option on the X431 that says "Get Security Code Online." The tool will connect to the LAUNCH server (requires internet and an active account) and pull the code from the vehicle’s ECU.
• After entering the correct code, the tool will display "Security Access Successful." If you get a rejection, move to the troubleshooting section below.

Step 4: Program the Smart Keys

With security access granted, follow the X431 on-screen instructions closely:

1. Select Program Smart Key.
2. For Key 1: Hold the new smart key near the push-button start detection zone. On the Empow, this zone is typically around the steering column or the center console cup holder area. The owner’s manual usually specifies the exact location.
3. Press Enter on the X431. The vehicle will respond with a single horn chirp or a dashboard message confirming the key has been learned.
4. For Key 2 (if applicable): Repeat the same process with the second key. The X431 will prompt you again.
5. After each successful match, the tool displays "Key Programming Successful."

A common mistake I’ve seen: Users place the key too far from the detection zone, resulting in a “No Key Detected” error. Press the key firmly against the area indicated in the manual. If it fails, try the center console storage bin—many modern GAC models use that spot.

Step 5: Test and Exit

1. Turn the ignition OFF, then back ON using one of the newly programmed keys (press the start button without your foot on the brake to enter accessory mode).
2. Start the engine to confirm the immobilizer deactivates and the car runs normally.
3. Exit the programming mode on the X431 and disconnect the tool. Test both keys by locking and unlocking the doors remotely and starting the engine.

Troubleshooting Common Issues

"Communication Failed" or Tool Cannot Connect

• Check the OBDII connector – Ensure it’s fully seated. Sometimes a loose connection is the culprit.
• Update the software – Go to the X431’s update center and check for any pending GAC Trumpchi updates. This is especially important for 2024 models.
• Toggle ignition – Turn the ignition OFF, wait 10 seconds, then back ON. The vehicle’s CAN network sometimes needs a reset.
• Battery voltage – If below 12.4V, use a jumper pack or battery charger. I keep a battery maintainer in my toolbox just for this.

Security Access Code Rejected

• Try factory defaults – 123456 and 1234 are the most common. If neither works, don’t guess—move to online retrieval.
• Use the X431’s automatic code retrieval – This requires a paid subscription on some LAUNCH models. If you don’t have an active account, you may need to purchase a token.
• Custom PIN set by previous owner – If you bought a used Empow and the code was changed, you’ll need dealer assistance. No aftermarket tool can bypass a custom PIN without some form of online authorization.
• Master key missing – Without at least one working master key, the X431 alone cannot program new fobs. See the "All Keys Lost" section below.

"All Keys Lost" – No Master Key Available

This is the hardest scenario. The LAUNCH X431 cannot program keys from scratch without a master key on the GAC Trumpchi Empow unless you purchase an additional "All Keys Lost" token from LAUNCH’s server. Even then, success depends on the specific X431 model and software revision.

• If your X431 supports it, look for a submenu labeled All Keys Lost or Erase All Keys under Key Programming. Follow the prompts—you’ll likely need to pay an online fee.
• If that option isn’t available, you must visit a GAC dealership or a specialized locksmith with factory-level equipment. Expect to pay $150–$300 for a full immobilizer reset.

New Key Does Not Start the Engine

• Dead key battery – Replace the CR2032 coin cell inside the fob.
• Wrong placement zone – Move the key closer to the start button or consult the owner’s manual for the exact reader location.
• Programming didn’t take – Re-run the procedure for that specific key only. If other keys still work, you can safely add the problematic key again without affecting the others.

Frequently Asked Questions (FAQ)

Do I need the LAUNCH X431 to program a GAC Trumpchi Empow key?

Yes, a professional-grade scan tool like the LAUNCH X431 is required. Generic OBDII code readers cannot access the immobilizer system or perform key matching. The X431 is one of the most affordable options that supports GAC vehicles.

Can I program a used key from another GAC vehicle?

No, smart keys are VIN-locked to the vehicle they were first paired with. A used key must be erased and then reprogrammed to your Empow’s VIN. The X431 can reset a blank key, but if the key still holds previous programming, you may need to use the Erase Key function first. Aftermarket blank keys are often the easiest solution.

How much does a LAUNCH X431 key programming cost?

The X431 scanner itself costs between $500 and $1,500 depending on the model. The GAC Trumpchi software is usually included at no extra cost. There is no per-key fee when you use the tool—only the upfront investment. If you need an online security code retrieval, some models charge a small fee per use (typically $5–$20).

Does the process work for 2022, 2023, and 2024 models?

Yes, the LAUNCH X431 supports all three model years. However, 2024 vehicles may require a software update. Before starting, connect your X431 to Wi-Fi and check for updates. I've seen the tool fail on a 2024 Empow because the technician skipped the update step.

What if my X431 shows "Key Number Exceeded"?

The GAC Trumpchi immobilizer only allows a maximum of 2–3 programmed keys. If you already have two keys stored and try to add a third, the tool will reject the command. Use the Delete Keys function in the same Key Programming menu to remove an existing key, then add the new one.

Final Tips and Maintenance

• Back up your security code. If you set a custom PIN or retrieved a code via the X431, write it down and store it in a password manager or a safe place. Losing this code will mean a trip to the dealer next time.
• Always program a spare key immediately. When you buy a used Empow with only one fob, order a second blank key and program it as soon as possible. It's far cheaper than dealing with a lost key emergency.
• Update your X431 firmware monthly. Automotive manufacturers change protocols with each model year. A monthly update ensures your tool can handle the newest vehicles.
• If a key stops working after a few months, don’t assume it’s a programming failure. Cold weather can weaken a coin cell battery. Replace the battery first—it’s a 5-minute fix.
