Important Notes for Remote Start:

• Range: The effective range of remote start varies but is generally around 100-300 feet, depending on environmental factors and battery strength.
• Run Time: For safety and fuel efficiency, the engine will typically run for 10-15 minutes after a remote start. It will then automatically shut off unless you enter the vehicle and start it normally with the push-button start or key ignition.
• Obstacles: Walls and other obstructions can reduce the range of the key fob signal. Ensure a clear line of sight between you and your vehicle for optimal performance.
• Vehicle Requirements: Remote start is an optional feature. Not all Chevy Malibu models are equipped with it. Check your vehicle’s specifications or owner’s manual to confirm if you have remote start capability.

Programming a New Key Fob for Your Chevy Malibu

Sometimes, you might need to program a new key fob, whether you’ve lost one, or added a remote start accessory kit. Programming a key fob generally requires specific tools and procedures to ensure it’s correctly recognized by your Chevy Malibu’s security system.

Tools You’ll Need:

• Scan Tool with Pass-Thru Programming Capability: This is a specialized diagnostic tool that can communicate with your vehicle’s computer system.
• Service Programming System (SPS): Software provided by GM that is used with the scan tool to program vehicle modules.
• EL-49642 SPS Programming Support Tool (Recommended): This tool helps maintain stable battery voltage during programming, crucial to prevent errors. Alternatively, a fully charged 12V jumper or booster pack (disconnected from AC voltage) can be used.

Preparation Before Programming:

1. Stable Battery Voltage: Ensure your Chevy Malibu’s battery is fully charged and stable. Voltage fluctuations can interrupt the programming process. Using the EL-49642 SPS tool or a booster pack is highly recommended.
2. Disable Accessories: Turn off or disable any systems that might draw power from the battery, such as interior lights, exterior lights (including daytime running lights), HVAC, and the radio.
3. Gather Necessary Information: You will need your vehicle’s VIN (Vehicle Identification Number) and the Authorization Code from your key fob kit.

Programming Steps Using SPS:

Note: The following steps are based on the original article and are intended as a guide. Always refer to the official Service Programming System (SPS) instructions and your vehicle’s service manual for the most accurate and up-to-date procedure.

1. Access SPS: Connect your scan tool to your Chevy Malibu’s data link connector (DLC) and access the Service Programming System (SPS) on your computer. Follow the on-screen prompts to connect to your vehicle.

2. Select BCM Programming: In the SPS Supported Controllers screen, choose “BCM Body Control Module – programming.” Follow the on-screen instructions.

3. Ignition and Key Preparation:

   • Key Ignition System: Insert the key into the ignition. Ensure any additional keys are at least 3 meters (approximately 10 feet) away from the vehicle.
   • Push Button Start System: Place the keyless entry transmitter (key fob) into the console programming pocket. The exact location is usually detailed in the SPS Help section. Ensure all additional transmitters are at least 3 meters away.

4. Immobilizer Learn – Delete Existing Keys (If Necessary):

   • Navigate to “IMMO Immobilizer Learn – Setup” in SPS.
   • Select “Program Transponder or Remote Key (Delete).”
   • Follow the on-screen instructions to delete existing keys. This step is crucial if you are replacing lost fobs or want to ensure only the new fobs are programmed. Skip this step if your vehicle is NOT equipped with Memory Seats and you are just adding fobs.

5. Immobilizer Learn – Add New Keys:

   • In SPS, under “IMMO Immobilizer Learn – Setup,” select “Program Transponder or Remote Key (Add).”
   • Follow the on-screen instructions to add your new key fobs. This process may take 10-12 minutes, and the progress bar might appear to stall – this is normal due to a security timer. Do not interrupt the process.
   • Once the Immobilizer Learn process is complete, press the Unlock button on the new key fob to exit the Immobilizer Learn mode. Repeat to add any additional new fobs.

6. BCM Setup:

   • Return to the SPS Supported Controllers screen and select “BCM Body Control Module – Setup.” Follow the on-screen instructions to complete the BCM setup.

7. Tire Pressure Monitor Sensor Learn (If Applicable):

   • For vehicles with UJM, you may need to perform a Tire Pressure Monitor Sensor Learn procedure during BCM setup. Use the EL-46079 tire pressure monitor diagnostic tool to activate each tire pressure sensor as directed by SPS.

8. Clear DTCs: After programming is complete, use the SPS function to “Clear All DTCs” (Diagnostic Trouble Codes).

9. Verify Functionality: Test all buttons on the newly programmed key fobs (lock, unlock, remote start, panic, trunk release) to ensure they are working correctly with your Chevy Malibu.

• Security Timer: Be patient during the Immobilizer Learn process, as the security timer delay is normal and essential for security protocols.
• DTC B389A: If DTC B389A sets immediately after programming a replacement BCM, it indicates the Immobilizer Learn procedure was not completed correctly. Repeat the Immobilizer Learn procedure.
• Key Positioning: Correct key positioning (in ignition or console pocket) is critical for successful programming. Refer to SPS Help for exact pocket locations and instructions.
• Erase All Fobs Option: If you need to erase all existing fobs and start fresh, SPS offers an “Erase/Program All Key Fobs” option. Be aware that this will make all previously programmed fobs inoperable unless they are reprogrammed in the same session.

Troubleshooting Unsuccessful Programming

If you encounter issues during the key fob programming process, here are some troubleshooting steps:

1. Check Connections: Ensure all connections between the scan tool, DLC, and your computer are secure.
2. Software Updates: Verify that your scan tool and TIS terminal operating software are up to date.
3. Reprogram Attempt: Do not turn the ignition OFF. Attempt to reprogram the ECU (Electronic Control Unit) again.
4. Ignition Cycle: If reprogramming fails, turn the ignition OFF for at least one minute, then turn it back ON and retry the programming.
5. ECU Replacement (Last Resort): If all else fails and the ECU still cannot be programmed, ECU replacement might be necessary. Consult a certified mechanic or dealership in this case.

Key Fob Management: Adding and Erasing

Your Chevy Malibu’s key fob system allows for managing multiple key fobs. You can add new fobs or erase old ones as needed.

Adding Key Fobs While Keeping Existing Ones:

If you want to add new key fobs without erasing the currently programmed ones (e.g., adding remote start fobs to existing keys), use the “Next Available Slot” option in SPS. This procedure programs new key fobs in sequential order (e.g., if you have fobs 1 and 2, the new ones will become 3 and 4).

Erasing All Key Fobs and Relearning:

If security is a concern, or you want to start with a clean slate, you can erase all programmed key fobs and relearn only the ones you want to use. Use the “Erase/Program All Key Fobs” option in SPS. Remember that this will require you to reprogram all desired fobs in one programming session.

Conclusion

Knowing how to start your Chevy Malibu with a key fob, including utilizing the remote start feature and understanding the programming process, enhances your vehicle ownership experience. While key fob programming can be technical and often requires specialized tools, understanding the steps involved empowers you to manage your vehicle’s keyless entry and security system effectively. For complex programming or troubleshooting issues, always consult with a certified automotive technician or your local Chevy dealership to ensure proper and secure operation of your Chevy Malibu.
