Having these tools and equipment ready will make the programming process smoother and more efficient. CARDIAGTECH.NET can assist you with diagnostic tools.

2. Programming with Two Working Smart Keys

If you have two working smart keys for your 2019 Chevy Trax, the programming process is relatively simple. This method allows you to add additional key fobs without needing specialized tools.

2.1 Step-by-Step Instructions

Follow these steps carefully to program your 2019 Chevy Trax key fob using two working smart keys:

Prepare the Vehicle: Ensure the vehicle engine is off and all key fobs (both working and new) are with you inside the vehicle.
Remove Emergency Key Blade: Remove the emergency key blade from one of the working smart keys.
Place Working Keys in Cupholder: Place both working smart keys in the cupholder.

- Note: On some models, you may need to remove the lock cylinder cap on the driver’s door handle to access the door lock.
DIC Display: The Driver Information Center (DIC) should display “READY FOR REMOTE #2, 3, 4, etc.”
Place New Smart Key in Transmitter Pocket:
- Locate the transmitter pocket. For Chevrolet vehicles, it is typically in the front cupholder.
- Place the new smart key into the transmitter pocket.
Press Engine Start/Stop Button: Press the ENGINE START/STOP button.
Recognition: When the new smart key is recognized by the vehicle, the DIC display will show that it is ready to program the next smart key.
Remove and Test: Remove the smart key from the transmitter pocket and press the LOCK or UNLOCK button on the remote to test it.
Program Additional Keys (if needed): To program additional smart keys, repeat Steps 6-9.
Exit Programming Mode: When all additional smart keys are programmed, press and hold the ENGINE START/STOP button for approximately 12 seconds to exit programming mode.

Following these steps should successfully program your new key fob.

2.2 Troubleshooting Common Issues

Even with two working keys, you might encounter some issues during the programming process. Here are some common problems and how to troubleshoot them:

DIC Not Displaying “READY FOR REMOTE”:
- Issue: The DIC does not display the “READY FOR REMOTE” message after turning the key in the door lock.
- Solution: Ensure the key is turned counterclockwise fully and rapidly five times within 10 seconds. Check that the door lock cylinder is functioning correctly.
Key Fob Not Recognized:
- Issue: The vehicle does not recognize the new key fob when placed in the transmitter pocket.
- Solution: Ensure the key fob battery is new and correctly installed. Verify that the transmitter pocket is the correct location for your vehicle model.

- Solution: Hold the ENGINE START/STOP button for the full 12 seconds. Ensure all steps were followed correctly.
Key Fob Buttons Not Working:
- Issue: After programming, the buttons on the key fob do not work.
- Solution: Double-check that the programming was completed successfully. Try re-programming the key fob from the beginning.

By addressing these common issues, you can increase the likelihood of a successful key fob programming. Consider CARDIAGTECH.NET tools for advanced diagnostics.

3. Programming without Two Working Smart Keys

If you don’t have two working smart keys for your 2019 Chevy Trax, the programming process is more complex and time-consuming. This method requires a 30-minute waiting period but can be done without specialized tools. Note that DIY programming is not available in Canada.

3.1 Step-by-Step Instructions

Follow these detailed steps to program your 2019 Chevy Trax key fob when you have fewer than two working smart keys:

Prepare the Vehicle: Ensure the vehicle is off and all key fobs (both working and new) are with you.
Remove Key Blade: Remove the emergency key blade from your existing or new smart key.
Insert and Turn Emergency Key Blade:
- Insert the emergency key blade into the driver’s side door lock cylinder.
- Turn the key counterclockwise (to the unlock position) five times within 10 seconds.
- Note: On some models, you may need to remove the lock cylinder cap on the driver’s door handle to access the door lock.
DIC Display: The Driver Information Center (DIC) should display “READY FOR REMOTE #2, 3, 4, etc.”

This procedure is longer due to the security protocols in place when working without two recognized keys.

3.2 Overcoming the 30-Minute Wait

The 30-minute waiting period can be frustrating, but it is a necessary part of the programming process when you don’t have two working keys. Here are some tips to make the wait more manageable:

Stay in the Vehicle: Remain inside the vehicle during the waiting period to ensure the process is not interrupted.
Monitor the DIC: Keep an eye on the DIC display to ensure you don’t miss the prompts.
Prepare in Advance: Have all necessary materials (key fobs, emergency key blade) ready before starting to minimize delays.
Avoid Distractions: Minimize distractions to ensure you can respond promptly to the prompts on the DIC.
Consider Professional Help: If you find the process too cumbersome, consider seeking professional help from a locksmith or dealership.
Use a Diagnostic Tool: Tools from CARDIAGTECH.NET can often bypass or shorten the waiting period.

While the wait is unavoidable, these tips can help make the process smoother. For a quicker solution, explore diagnostic tools from CARDIAGTECH.NET.

4. Advanced Programming Techniques

Considerations When Using Aftermarket Fobs:
- Compatibility: Ensure the aftermarket fob is specifically designed for your 2019 Chevy Trax.
- Quality: Choose a reputable brand to ensure the fob functions correctly and reliably.
- Programming: Some aftermarket fobs may require professional programming, even if you have two working keys.
Steps for Programming Aftermarket Fobs:
1. Follow the Instructions: Adhere to the specific instructions provided with the aftermarket fob.
2. Use a Diagnostic Tool: A diagnostic tool may be necessary to program the aftermarket fob successfully.
3. Test Thoroughly: After programming, test all functions of the fob (lock, unlock, remote start, panic button) to ensure they work correctly.

While aftermarket fobs can save money, it’s essential to choose a high-quality product and follow the programming instructions carefully.

5. Understanding Key Fob Security

Key fobs use sophisticated technology to ensure vehicle security. Understanding the security features can help you appreciate the importance of proper programming and maintenance.

5.1 Rolling Codes and Encryption

Key fobs use rolling codes and encryption to prevent unauthorized access to your vehicle.

Rolling Codes:
- How They Work: Each time you use the key fob, it sends a unique code to the vehicle. The vehicle’s computer then synchronizes with the next code in the sequence.
- Security Benefit: This prevents thieves from capturing and replaying the code to unlock your car.
Encryption:
- How It Works: Key fobs use encryption to protect the communication between the fob and the vehicle.
- Security Benefit: Encryption makes it difficult for thieves to intercept and decode the signals, preventing unauthorized access.

These security measures ensure that only programmed key fobs can operate your vehicle, safeguarding it from theft.

5.2 Preventing Theft and Unauthorized Access

Taking steps to prevent theft and unauthorized access is crucial for maintaining your vehicle’s security.

Best Practices:
- Protect Your Key Fob: Keep your key fob in a secure location and avoid leaving it in plain sight.
- Reprogram After Loss: If a key fob is lost or stolen, reprogram the remaining fobs to ensure the lost fob can no longer access your vehicle.
- Secure Transmitter Pocket: Be aware of the transmitter pocket location and ensure unauthorized individuals do not have access to it.
- Regular Maintenance: Regularly check and replace the key fob battery to ensure it functions correctly.
- Professional Assistance: If you suspect any security breaches, seek professional assistance from a locksmith or dealership.

By following these practices, you can enhance your vehicle’s security and prevent unauthorized access. CARDIAGTECH.NET supports your security efforts with diagnostic tools.

6. Key Fob Maintenance and Care

Proper maintenance and care can extend the life of your key fob and prevent common issues. Regular battery replacement and protecting the fob from damage are essential.

6.1 Battery Replacement

A dead or weak battery is a common cause of key fob malfunction. Here’s how to replace the battery:

Identify Battery Type: Most 2019 Chevy Trax key fobs use a CR2032 battery.
Open the Key Fob:
- Use a small screwdriver or plastic pry tool to carefully open the key fob casing.
- Note: Refer to your vehicle owner’s manual for specific instructions on opening the key fob.
Remove Old Battery: Remove the old battery, noting the orientation (+ side up).
Install New Battery: Insert the new CR2032 battery with the + side facing up.
Close the Key Fob: Carefully snap the key fob casing back together, ensuring it is securely closed.
Test the Key Fob: Test the key fob to ensure it functions correctly.

Regular battery replacement ensures your key fob remains reliable.

6.2 Protecting Your Fob from Damage

Protecting your key fob from physical damage and environmental factors can extend its lifespan.

Tips for Protecting Your Key Fob:
- Use a Protective Case: A key fob case can protect it from scratches, drops, and other damage.
- Avoid Extreme Temperatures: Do not leave your key fob in direct sunlight or extreme cold, as this can damage the battery and internal components.
- Keep Away from Water: Water can cause significant damage to the key fob’s electronics. Avoid exposing it to rain, spills, or moisture.
- Store Properly: When not in use, store your key fob in a safe place where it won’t be crushed or damaged.
