Understanding the Programming Process for Your Chevy Malibu Key Fob
Programming a key fob for your 2012 Chevy Malibu involves using specific tools and following a precise sequence to sync the new fob with your vehicle’s Body Control Module (BCM). This process is necessary because the key fob communicates wirelessly with your car to control functions like locking/unlocking doors, remote start (if equipped), and activating the alarm system. For 2012 Chevy Malibu models, the programming typically requires a scan tool with pass-thru programming capability and access to the Service Programming System (SPS).
It’s important to note that if your 2012 Chevy Malibu was originally equipped with the Accessory Remote Start kit (check RPO code S6P), the key fob programming might be simpler. In some cases, vehicles with RPO code S6P already have the correct system software, and programming new fobs becomes a straightforward learning process. However, for vehicles without this pre-installed feature, or when adding the remote start functionality, a more detailed programming procedure is necessary.
Tools You’ll Need for 2012 Chevy Malibu Key Fob Programming
To successfully program a new key fob for your 2012 Chevy Malibu, you’ll need specific tools. Having these ready before you begin will ensure a smooth and efficient process.
- Scan Tool with Pass-Thru Programming Capability: This is essential for communicating with your vehicle’s computer system and initiating the programming sequence. Ensure your scan tool is compatible with GM vehicles and supports SPS.

-
Navigate to BCM Programming:
- In the SPS software, navigate to the “Supported Controllers” or similar screen.
- Select “BCM Body Control Module” and then choose “programming.”
- Follow the on-screen instructions provided by the SPS.
-
Ignition and Key Positioning:
- Key Ignition System: If your 2012 Chevy Malibu has a 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: If your vehicle has a push-button start, place the keyless entry transmitter into the console programming pocket. Refer to your vehicle’s manual or the SPS Help section for the exact location of this pocket. Ensure all additional transmitters are at least 3 meters away.
-
Immobilizer Learn Setup:
- After BCM programming, remain in the SPS and navigate back to the “Supported Controllers” screen.
- Select “IMMO Immobilizer Learn – Setup.”
- Choose “Program Transponder or Remote Key (Delete)” if you want to erase existing keys, or “Program Transponder or Remote Key (Add)” to add new keys while keeping existing ones.
-
Deleting Existing Keys (Optional but Recommended):
- If you choose to delete existing keys (especially if you suspect a key is lost or stolen), follow the on-screen instructions in SPS to “Delete existing keys and remotes.”
- Complete the deletion process as prompted by the SPS.
- Note: Deleting keys without the remote start button will render them inoperable. However, this step is necessary for new transponders to correspond with memory seat locations (if equipped). If your 2012 Chevy Malibu does not have memory seats, you can skip this step.
-
Adding New Keys:
- If you chose “Program Transponder or Remote Key (Add),” follow the SPS on-screen instructions to add new key fobs.
- The system will guide you through programming each new fob. Typically, this involves pressing certain buttons on the fob as instructed.
- Note: The programming process may take between 10-12 minutes, and progress might appear to pause. This is a normal security timer response, and you should not interrupt or restart the process.
-
Complete Immobilizer Learn and Exit:
- Once the Immobilizer Learn process is complete, the SPS will indicate success.
- Press the “Unlock” button on the newly programmed keyless entry transmitter to exit the Immobilizer Learn mode.
