Losing or damaging your car key fob can be a major inconvenience. For 2012 Chevrolet Malibu owners, understanding how to program a new key fob can save you time and money compared to dealership services. This guide provides a detailed, step-by-step approach to programming your 2012 Malibu key fob, ensuring you regain access and control over your vehicle’s keyless entry and remote start functionalities.
Understanding Key Fob Programming for Your 2012 Malibu
Modern vehicles like the 2012 Chevy Malibu utilize sophisticated security systems that require electronic key fob programming. This process ensures that only authorized key fobs can communicate with your car’s computer system to unlock doors, start the engine (if equipped with remote start), and activate other features. Programming a key fob involves syncing the new fob’s unique electronic signature with your vehicle’s Body Control Module (BCM).
For 2012 Malibu models, the programming process generally requires a scan tool with Pass-Thru programming capability and access to the Service Programming System (SPS). While it might sound complex, this guide will break down the procedure into manageable steps.
Step-by-Step Programming Guide for Your 2012 Malibu Key Fob
Before you begin, gather the necessary tools and ensure you have all the components from your key fob kit.
Preparing for Programming
Tools and Kit Contents:
- New Key Fobs: Ensure you have the correct key fobs for your 2012 Malibu.
- Scan Tool: A professional-grade scan tool with Pass-Thru programming capabilities is essential. This tool allows communication with your vehicle’s computer system.
- Service Programming System (SPS): Access to SPS software, often through a subscription service, is required to program GM vehicles.
- Installation Instructions & Authorization Code: Your key fob kit should include installation instructions and an authorization code label. Keep this information handy.
Pre-Programming Checks:
- Remote Start Option (RPO Code S6P): If your 2012 Malibu was factory-equipped with remote start (check your vehicle’s RPO code listing for S6P), programming might be simpler. In some cases, no additional programming beyond learning the new fobs to the vehicle is needed. You can verify this using the Investigate Vehicle History (IVH) system.
- Accessory Remote Start Kit: If you are adding an accessory remote start kit and your vehicle doesn’t have RPO code S6P, you will likely need to contact TCSC (Technical Customer Support Center) to obtain a VCI number.

Have your Vehicle Identification Number (VIN) and the Authorization Code from your kit ready when you call.
Programming with SPS
This section outlines the core programming procedure using the SPS.
Important Notes Before Starting:
- Do NOT program a module unless specifically instructed by a service procedure. Incorrect programming can lead to malfunctions.
- Ensure your programming tool has the latest software updates.
- Maintain stable battery voltage throughout the process. Voltage fluctuations can cause programming failures or ECU damage. Use a Programming Support Tool (like EL-49642 SPS) or a fully charged 12V jumper/booster pack (disconnected from AC supply – do not use a battery charger).
- Turn OFF unnecessary vehicle systems (interior/exterior lights, HVAC, radio) to minimize battery load.
- Follow SPS prompts carefully regarding ignition switch positions.
- Clear DTCs (Diagnostic Trouble Codes) after programming.
Programming Steps:
-
Connect Programming Support Tool: Install the EL-49642 SPS programming support tool to maintain stable voltage.
-
Access SPS: Open the Service Programming System (SPS) on your scan tool and follow the on-screen instructions.
-
Select BCM Programming: On the SPS Supported Controllers screen, choose “BCM Body Control Module – programming.”
-
Ignition Preparation:
- Key Ignition System: Ensure the key is in the ignition and all other keys are at least 3 meters (approximately 10 feet) away from the vehicle.
- Push Button Start System: Place the keyless entry transmitter in the console programming pocket. Refer to the SPS Help section for the exact pocket location. Keep all other transmitters at least 3 meters away.

BCM Programming Process: Follow the SPS on-screen prompts to program the BCM. Note: This step can take 10-12 minutes, and progress might appear to pause. This is normal for security protocols. Do not interrupt or restart the process.
-
Immobilizer Learn – Setup: After BCM programming, navigate to the “IMMO Immobilizer Learn – Setup” screen in SPS.
Adding or Replacing Key Fobs
Now, you’ll program the key fobs themselves. You have options to delete existing keys or add new ones.
Deleting Existing Keys (Optional, but Recommended for Security):
- Select Delete Option: On the Immobilizer Learn screen, choose “Program Transponder or Remote Key (Delete).”
- Follow On-Screen Instructions: SPS will guide you through deleting existing keys and remotes.
- Exit Immobilizer Learn Mode: Once deletion is complete, follow the prompts to exit Immobilizer Learn mode. Repeat to delete additional remotes if needed.
- Note: Deleting keys without remote start will make those keys inoperable. This step is necessary if you want new transponders to correspond with memory seat locations (if equipped). Skip this step if your vehicle does not have memory seats and you are not concerned about old fobs still working.
Adding New Keys:
- Select Add Option: On the Immobilizer Learn screen, choose “Program Transponder or Remote Key (Add).”
- Follow On-Screen Instructions: SPS will guide you through adding new transponders or remote keys.
- Unlock Button Activation: When Immobilizer Learn is complete, press the “Unlock” button on the newly programmed keyless entry transmitter to exit Immobilizer Learn mode. Repeat to add more remotes.
Finalizing Programming:
- BCM Setup: Return to the SPS Supported Controllers screen and select “BCM Body Control Module – Setup.” Follow the on-screen instructions.
- Check Driver Information Center: Look for any additional messages or calibration instructions on your driver information center display.
- Clear DTCs: At the end of programming, use the SPS function to “Clear All DTCs.”
- Verify System Operation: Cycle the ignition ON to OFF, exit the vehicle, and test all key fob functions (lock, unlock, remote start, panic button) to ensure they work correctly.
Troubleshooting Unsuccessful Programming
If programming is interrupted or unsuccessful:
- Do NOT turn the ignition OFF.
- Check Connections: Ensure all connections between the ECU, DLC (Data Link Connector), and programming tool are secure. Verify your TIS terminal operating software is up to date.
- Retry Programming: Attempt to reprogram the ECU again.
- Ignition Cycle (if Reprogramming Fails Again): If it still fails, turn the ignition OFF for at least one minute, then back ON, and retry programming.
- ECU Replacement (Last Resort): If programming continues to fail, the ECU might need replacement.
Important Considerations and Tips
- Master Keys and Seat Memory: The first two key fobs programmed will be designated as master keys and linked to memory seat positions (if equipped).
- Erase All Fobs and Relearn (Advanced): If you want to erase all existing fobs and start fresh, use the “Erase/Program All Key Fobs” function in the BCM Configuration/Reset menu of your scan tool. Be aware that all transmitters must be programmed in a single session when using this option.
- Adding Fobs in Sequence (Keeping Existing Fobs): To add new fobs without erasing existing ones (e.g., keeping fobs 1 & 2 and adding new ones as 3 & 4), use the “Next Available Slot” function in the BCM Configuration/Reset menu.
- Avoid Programming Near Other Vehicles: Do not program key fobs near other vehicles that are also in programming mode to prevent accidental programming to the wrong vehicle.
- Tire Pressure Monitor Sensor Learn (if applicable): If you performed a Tire Pressure Monitor Sensor Learn during BCM setup, you might need to use the EL-46079 tire pressure monitor diagnostic tool to activate each sensor, especially on vehicles with UJM (tire pressure monitoring system).
Conclusion
Programming a key fob for your 2012 Chevy Malibu requires specific tools and a systematic approach. By following these steps and guidelines, you can successfully program new key fobs and maintain the security and convenience of your vehicle’s keyless entry system. Remember to prioritize stable voltage, use the correct programming tools, and carefully follow the SPS prompts for a smooth and successful key fob programming experience. Consult a professional if you encounter difficulties or are unsure about any part of the procedure.
