Losing or damaging your key fob can be a major inconvenience. Fortunately, programming a new key fob for your 2012 Chevy Malibu can often be done at home, provided you have the right tools and follow the correct procedure. This guide will walk you through the process, ensuring you can regain full access and functionality of your vehicle.
Before you begin, it’s important to understand the tools and prerequisites necessary for programming a key fob for your 2012 Chevy Malibu. This process generally requires a scan tool with pass-thru programming capability and access to the Service Programming System (SPS). It’s also crucial to ensure your vehicle’s battery voltage is stable throughout the programming process to avoid any interruptions or potential damage to the electronic control units (ECUs).
Tools and Requirements
- Scan Tool: You will need a scan tool that supports pass-thru programming. This tool allows you to communicate with your vehicle’s computer system and program new key fobs.
- Service Programming System (SPS): Access to SPS is essential for downloading the necessary software and calibrations for your vehicle.
- Stable Power Supply: Maintaining a stable battery voltage is critical. Using a tool like the EL-49642 SPS Programming Support Tool is recommended. Alternatively, a fully charged 12V jumper or booster pack (disconnected from AC) can be used. Avoid using a battery charger as it can cause voltage fluctuations.
- Key Fobs: Ensure you have the correct replacement key fobs for your 2012 Chevy Malibu.
- Authorization Code: For certain procedures, you may need an authorization code, especially if you are adding a remote start feature. This code is often provided with the key fob kit.
Pre-Programming Checks
Before starting the programming procedure, take these steps:
-
Accessory Remote Start Check: If your vehicle was ordered with the Accessory Remote Start kit (RPO code S6P), programming might not be required. You can verify this by checking your VIN in the Investigate Vehicle History system (IVH). If S6P is listed, the vehicle is pre-programmed, and simply learning the new fobs might be sufficient.
-
Adding Remote Start Feature: If you are adding the 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. You will need your vehicle’s VIN and the Authorization Code from the kit. Contact numbers are typically:
- United States: 1-888-337-1010
- Canada (English): 1-800-828-6860
- Canada (French): 1-800-503-3222
-
Vehicle Preparation: To ensure stable voltage and prevent interruptions, turn OFF or disable any systems that could load the vehicle’s battery. This includes interior lights, exterior lights (including daytime running lights), HVAC, and the radio.
Programming Procedure
The following steps outline the general procedure for programming a key fob for your 2012 Chevy Malibu using SPS. Always follow the on-screen prompts provided by the SPS for your specific vehicle and scan tool.
Step 1: Accessing the Service Programming System (SPS)
- Install the EL-49642 SPS programming support tool or connect a stable power supply.
- Access the Service Programming System (SPS) with your scan tool and follow the on-screen instructions to connect to your vehicle.
- On the SPS Supported Controllers screen, select BCM Body Control Module – programming.
Step 2: Preparing for Programming
Depending on your vehicle’s ignition system, follow the appropriate steps:
- Key Ignition System: Ensure the key is in the ignition. Remove any additional keys from the vehicle area (at least 3 meters away).
- 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 for your Malibu model. Remove all additional transmitters from the vehicle area (at least 3 meters away).
Step 3: Initiating Immobilizer Learn
- On the SPS Supported Controllers screen, select IMMO Immobilizer Learn – Setup.
- On the next screen, you will have options for programming. To delete existing keys before adding new ones, select Program Transponder or Remote Key (Delete). If you are only adding keys, you can typically skip the deletion step and select Program Transponder or Remote Key (Add).
Step 4: Deleting Existing Keys (Optional but Recommended)
Deleting existing keys is a good security practice, especially if you are unsure who might have access to the old key fobs.
- Follow the on-screen instructions to delete existing keys and remotes.
- Once the deletion process is complete, follow the on-screen prompts to exit the Immobilizer learn mode.
- Repeat this step to delete any additional remotes if needed.
Step 5: Adding New Key Fobs
- If you haven’t already, on the SPS Supported Controllers screen and IMMO Immobilizer Learn – Setup screen, select Program Transponder or Remote Key (Add).
- Follow the on-screen instructions to program each new key fob. Typically, this involves pressing certain buttons on the key fob as prompted by the SPS.
- After programming each key fob, you may need to press the Unlock button on the transmitter to exit the Immobilizer Learn mode.
- Repeat this step to add any additional remotes.
Step 6: BCM Setup and Finalization
- On the SPS Supported Controllers screen, select BCM Body Control Module – Setup and follow the on-screen instructions to complete the BCM setup.
- Check the driver information center display for any additional messages or calibration instructions and follow them accordingly.
- At the end of programming, use the SPS function to Clear All DTCs (Diagnostic Trouble Codes).
Step 7: Verifying Programming
- Cycle the ignition from ON to OFF.
- Exit the vehicle.
- Test all functions of each programmed key fob (lock, unlock, remote start if applicable) to ensure they are working correctly.
Erasing All Key Fobs and Re-learning
If you want to erase all previously programmed key fobs and start fresh, you can use the “Erase/Program All Key Fobs” function. This is useful when you are unsure how many key fobs are programmed to the vehicle or for security reasons.
- With your scan tool, access the Body Control Module Configuration/Reset Functions menu.
- Select Add/Replace Key Fobs.
- Select Erase/Program Fobs. This will erase all learned transmitters.
- Follow the on-screen instructions to program the new key fobs sequentially.
- After programming, cycle the ignition and verify the operation of the new key fobs.
Adding Key Fobs to the Next Available Slot
If you want to add new key fobs without erasing the existing ones, you can use the “Next Available Slot” function. This will program the new fobs in the next available memory slots.
- With a scan tool, access the Body Control Module Configuration/Reset Functions menu.
- Select Add/Replace Key Fobs.
- Select Next Available Slot.
- Follow the on-screen instructions to program the new key fobs.
- After programming, cycle the ignition and verify the operation of all key fobs.
Unsuccessful Programming Recovery
If you encounter an interrupted or unsuccessful programming event, do not panic. Follow these recovery steps:
- Do NOT turn the ignition OFF.
- Check all connections: Ensure that all ECU, DLC (Data Link Connector), and programming tool connections 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, turn the ignition OFF for at least one minute, then turn it ON and retry programming.
- ECU Replacement (Last Resort): If the ECU still cannot be programmed after these steps, ECU replacement might be necessary. Consult a professional technician in this case.
Important Notes
- All transmitters must be programmed in a single programming sequence when using “Erase/Program All Key Fobs”. If you don’t program all desired fobs at this time, they will become inoperative and require reprogramming.
- Avoid programming transmitters near other vehicles that are in programming mode. This can lead to programming transmitters to the wrong vehicle.
- Master Keys: Remember that the first two transmitters programmed are often designated as master keys and may be linked to memory seat positions if your vehicle is equipped with that feature.
Programming a key fob for your 2012 Chevy Malibu requires careful attention to detail and the right tools. By following these steps and adhering to the safety precautions, you can successfully program your new key fobs and restore the convenience and security of remote vehicle access. If you are uncomfortable with any part of this procedure, it is always recommended to seek assistance from a qualified automotive technician.
