2023 Chevrolet Malibu: Key Fob Programming Guide

Quick reference

Step-by-step on-board programming

Good news for owners of the 2023 Chevrolet Malibu without the push-to-start system: you can program a new remote key fob at home without any special tools. This procedure will add a new remote to your vehicle's system. Note that you must have at least one already programmed key to initiate this process.

If your Malibu has a push-button start, this on-board procedure will not work. You will need a diagnostic scan tool, available from a dealer or an automotive locksmith, to program a new fob.

For models with a traditional ignition:

1. Get in the car and close all the doors.
2. Insert an existing, programmed key into the ignition.
3. Turn the key to the ON position (the position right before starting the engine) five times in quick succession. On the fifth turn, leave the key in the ON position.
4. Check the Driver Information Center (DIC): The screen on your dashboard should display a message like "Ready for Remote #2". This indicates the vehicle has entered programming mode.
5. Program the new fob: Take your new, unprogrammed key fob. Press and hold the LOCK and UNLOCK buttons simultaneously for approximately 15 seconds.
6. Listen for confirmation: The car will chime, and the DIC will show a message indicating that the new remote has been programmed successfully.
7. Program additional remotes: If you have more remotes to program, you can repeat step 5 with the next fob immediately. The system will recognize each new remote in sequence (e.g., "Ready for Remote #3").
8. Exit programming mode: Once you have programmed all your new remotes, turn the ignition to the OFF position to exit the programming mode.
9. Test all remotes (including the original ones) to ensure they all lock, unlock, and (if applicable) remote start the vehicle correctly.

Battery replacement

Replacing the battery in your 2023 Malibu fob is a simple task. The required battery is a CR2032, which is widely available.

1. Locate the release button on the side of your key fob. Press it to release the emergency metal key blade.
2. Remove the key blade from the fob.
3. Create an opening: Use the key blade or a small flathead screwdriver to carefully pry the two halves of the key fob apart. There is usually a small notch or seam where you can insert the tool.
4. Separate the halves: Gently work your way around the seam until the fob casing pops open.
5. Replace the battery: Note the orientation of the old CR2032 battery before removing it. The positive (+) side usually faces up. Pop the new battery into place in the same orientation.
6. Reassemble the fob: Snap the two halves of the casing back together firmly.
7. Re-insert the key blade until it clicks into place.

Where to buy a replacement fob

• Chevrolet Dealership: This is the most expensive but most reliable option. The fob is guaranteed to be a genuine OEM part, and they will handle the programming and key cutting. Expect to pay in the range of $200-$400 for the fob and programming service.
• Automotive Locksmith: A professional locksmith can often source OEM or high-quality aftermarket fobs for a lower price than the dealer. They have the necessary scan tools for programming push-to-start models and can cut the emergency key blade on-site. This is often the best balance of cost and convenience, with prices typically ranging from $150-$300.
• Online (Amazon, eBay, etc.): You can find fobs online for as little as $20-$50. However, the quality and compatibility can be a gamble. While you might save money on the part, you still need to pay a locksmith or dealer to program it (if it's a push-to-start model) and cut the key. Be cautious of counterfeit or incompatible products.

If on-board programming isn't supported

If your 2023 Malibu has a push-button ignition, on-board programming is not an option. This is because modern vehicles have sophisticated immobilizer systems that require a secure connection with a diagnostic scan tool to authorize a new key. The transponder chip inside the key fob must be registered with the car's computer to allow the engine to start.

This security measure prevents theft but means you cannot DIY the programming. You will need to contact the dealer or a mobile locksmith who has the proprietary software to access your vehicle's immobilizer system. The cost for this service typically includes a fee for the programming itself plus the cost of the fob, as outlined above.
