Whether you’re adding a spare, replacing a lost fob, or upgrading to a remote start system, understanding how to use a 2012 Chevy Malibu Key Fob Programmer is crucial.

This article will provide a detailed, step-by-step approach to programming your 2012 Chevy Malibu key fobs. We’ll cover the necessary tools, procedures, and important considerations to ensure a successful programming experience.

Understanding Your 2012 Chevy Malibu Key Fob System

Before diving into the programming process, it’s helpful to understand a few key aspects of your 2012 Chevy Malibu’s key fob system. For certain models, particularly those ordered with the Accessory Remote Start kit, the key fob programming may be simpler or even pre-configured.

Remote Start Pre-configuration (RPO Code S6P):

If your 2012 Chevy Malibu was originally equipped with the Accessory Remote Start kit, indicated by RPO code S6P on your vehicle’s build list, you might not need extensive programming. You can verify this by checking your Vehicle Identification Number (VIN) in the GM’s Investigate Vehicle History (IVH) system. If RPO code S6P is present, the vehicle’s software is already set up for remote start, and programming new key fobs might be as straightforward as learning them to the vehicle.

Adding Accessory Remote Start:

If you are adding the Accessory Remote Start kit to a 2012 Chevy Malibu that was not originally equipped with it (and S6P is not listed in the vehicle’s RPO build), the process is slightly more involved. In this case, you’ll likely need to contact GM’s Technical Customer Support Center (TCSC) to obtain a VCI number.

United States: 1-888-337-1010
Canada (English): 1-800-828-6860
Canada (French): 1-800-503-3222

When contacting TCSC, ensure you have your vehicle’s VIN and the Authorization Code from your remote start kit. This VCI number will grant you access to the necessary software to enable the remote vehicle start option during the programming process.

Essential Tools for Key Fob Programming

Programming key fobs for your 2012 Chevy Malibu typically requires specialized tools. Here’s what you’ll likely need:

Scan Tool with Pass-Thru Programming Capability: A professional-grade scan tool is necessary to communicate with your vehicle’s computer systems. “Pass-Thru” capability is crucial, as it allows the scan tool to interface with the vehicle’s Body Control Module (BCM) and other modules for programming.
Service Programming System (SPS): GM’s SPS software is often required to perform the actual programming. This software, accessed through a subscription, provides the necessary calibrations and procedures for programming vehicle modules.
EL-49642 SPS Programming Support Tool (Voltage Stabilizer) – Recommended: Maintaining stable battery voltage is critical during programming. Voltage fluctuations can lead to programming failures or even damage to the vehicle’s electronic control units (ECUs). The EL-49642 or a similar voltage stabilizer is highly recommended to ensure a consistent power supply throughout the programming process.
Fully Charged 12V Jumper or Booster Pack (Alternative): If a voltage stabilizer isn’t available, a fully charged jumper or booster pack can be used. However, it’s crucial to disconnect it from the AC voltage supply during programming to avoid voltage spikes. Do NOT use a battery charger directly.

Step-by-Step Guide: Programming Your 2012 Chevy Malibu Key Fob

Important Preparations:

Before you begin the programming procedure, ensure you follow these crucial steps:

Review the Entire Procedure: Familiarize yourself with all the steps before starting.
Software and Tool Readiness: Ensure your scan tool is updated with the latest software and securely connected to the vehicle’s data link connector (DLC).
Stable Power Supply: Connect the EL-49642 SPS Programming Support Tool or a fully charged booster pack (disconnected from AC power).
Minimize Battery Load: Turn OFF or disable all unnecessary vehicle systems that draw power, such as interior lights, exterior lights (including daytime running lights), HVAC, and the radio.

Programming Procedure via SPS:

Access SPS: Open the Service Programming System (SPS) on your scan tool and follow the on-screen prompts.
Select BCM Programming: On the SPS Supported Controllers screen, choose “BCM Body Control Module – programming.” Follow the on-screen instructions.
Ignition Preparation (Key Type Dependent):
- 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 into the console programming pocket. Refer to the SPS Help section for the exact pocket location for your Malibu. Ensure all additional transmitters are at least 3 meters away.
Immobilizer Learn Setup (Key Deletion – Optional):
- Deleting Existing Keys (Without Remote Start Button): If you want to delete old keys (rendering them inoperable), on the SPS Supported Controllers screen, select “IMMO Immobilizer Learn – Setup.” On the next screen, select “Program Transponder or Remote Key (Delete).” Follow the on-screen instructions to delete existing keys. 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.
Immobilizer Learn Setup (Key Addition):
- Adding New Keys (With Remote Start Button): To add new key fobs, on the SPS Supported Controllers screen, select “IMMO Immobilizer Learn – Setup.” On the next screen, select “Program Transponder or Remote Key (Add).” Follow the on-screen instructions to add your new key fobs.
Complete Immobilizer Learn: Once the Immobilizer Learn process is complete, press the “Unlock” button on the keyless entry transmitter to exit the Immobilizer Learn mode. Repeat step 5 to add any additional remotes.
BCM Setup: On the SPS Supported Controllers screen, select “BCM Body Control Module – Setup” and follow the on-screen instructions.
Check for Additional Instructions: Observe the driver information center display for any further calibration instructions. If none are present, programming is complete.
Clear DTCs: At the end of programming, use the SPS to “Clear All DTCs” (Diagnostic Trouble Codes).

Important Notes During Programming:

Programming Time: The key programming step may take 10-12 minutes. Progress might seem to pause during this time; this is normal due to security timers. Do not interrupt or restart the process.
DTC B389A: If DTC B389A sets immediately after programming a replacement BCM, the Immobilizer Learn procedure was not completed correctly. Repeat the Immobilizer Learn procedure.
Tire Pressure Monitor Sensor Learn (If Applicable): For vehicles with UJM, when performing the Tire Pressure Monitor Sensor Learn during BCM setup, the EL-46079 tire pressure monitor diagnostic tool must be used to activate each tire pressure sensor.
Key Designation: The first two transmitters programmed will be designated as master keys and will be associated with memory seat positions (if equipped).

Troubleshooting Unsuccessful Programming

If you encounter an interrupted or unsuccessful programming event, follow these recovery steps:

Do Not Turn Ignition OFF: Leave the ignition ON.
Check Connections: Ensure all connections to the ECU, DLC, 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 reprogramming fails again, turn the ignition OFF for at least one minute. Then, turn the ignition ON and retry programming.
ECU Replacement (Last Resort): If the ECU still cannot be programmed after these steps, ECU replacement may be necessary.
