How to Replace a 2018 Chevy Malibu Key Fob Battery

If you’re experiencing issues with your 2018 Chevy Malibu key fob, a dead battery might be the culprit. Luckily, replacing the key fob battery is a quick and straightforward process you can handle yourself. This guide will provide a step-by-step walkthrough, ensuring you’re back in control of your Malibu in no time.

Understanding Your Chevy Malibu Key Fob

Before diving into the replacement process, it’s helpful to understand the components of your key fob. The 2018 Chevy Malibu key fob typically houses two types of batteries:

• Keyless Entry Battery: This battery powers the lock, unlock, and panic functions of your key fob.
• Remote Start Battery: If your Malibu is equipped with remote start, a separate battery powers this feature.

This guide focuses on replacing the keyless entry battery, as it’s the one most users interact with regularly.

Signs You Need a New Key Fob Battery

Here are a few telltale signs that your key fob battery might be on its way out:

• Decreased Range: You find yourself needing to stand closer to your vehicle for the key fob to work.
• Intermittent Functionality: The lock, unlock, or panic buttons work only sporadically.
• No Response: The key fob fails to communicate with your vehicle altogether.

Gathering the Necessary Tools

To replace your 2018 Chevy Malibu key fob battery, you’ll need a few simple tools:

• Small Flat-head Screwdriver: This will be used to pry open the key fob casing.
• CR2032 Battery: This is the standard battery type for most 2018 Chevy Malibu key fobs.

It’s generally a good idea to purchase a high-quality CR2032 battery from a reputable brand to ensure optimal performance and longevity.

Step-by-Step Guide to Replacing the Battery

Follow these easy steps to replace your 2018 Chevy Malibu key fob battery:

1. Locate the Key Ring Release: On the back of your key fob, find the small button or switch that releases the metal key ring.
2. Remove the Metal Key: Press the key ring release and carefully slide the metal key out of the fob.
3. Identify the Seam: With the metal key removed, examine the key fob for a small seam or groove running along its edge.
4. Insert the Screwdriver: Gently insert the flat-head screwdriver into the seam and carefully pry open the casing. Be cautious not to apply excessive force, as this could damage the fob.
5. Separate the Halves: Once the casing is slightly separated, you can use your fingers to carefully pull the two halves apart.
6. Locate the Battery: Inside the key fob, you’ll see the CR2032 battery nestled within.
7. Remove the Old Battery: Gently pry out the old battery using the tip of your screwdriver or your fingernail. Avoid touching the battery’s flat surfaces to prevent transferring oils and potentially shortening its lifespan.
8. Insert the New Battery: Align the positive (+) side of the new CR2032 battery with the positive (+) marking inside the key fob and carefully press it into place.
9. Reassemble the Key Fob: Align the two halves of the key fob casing and press them firmly together until you hear a click, indicating they are securely closed.
10. Reinsert the Metal Key: Slide the metal key back into its slot on the key fob until it locks into place.

Testing Your New Key Fob Battery

After replacing the battery, it’s essential to test the key fob’s functionality. Try locking and unlocking your vehicle’s doors using the key fob buttons. If the vehicle responds correctly, the battery replacement was successful.

What if the Key Fob Still Doesn’t Work?

If you’ve replaced the battery and your key fob is still not functioning correctly, there could be other issues at play. Here are a few possibilities:

• Key Fob Programming: The key fob might need to be reprogrammed to your vehicle.
• Internal Key Fob Damage: There could be damage to the key fob’s internal circuitry.
• Vehicle Receiver Issues: The receiver in your vehicle that communicates with the key fob might be faulty.

In such cases, it’s best to consult a qualified automotive locksmith or your Chevy dealership for further diagnosis and assistance.
