How to Change Battery in 2021 Silverado Key Fob

If you’re experiencing issues with your 2021 Silverado key fob, a dead battery might be the culprit. Luckily, replacing it is a simple DIY task you can accomplish in minutes. This guide provides a step-by-step walkthrough to get your key fob back in action.

Why is My Silverado Key Fob Not Working?

Before we dive into the battery replacement, let’s address the elephant in the room: why is your key fob acting up? While a dead battery is a common reason, other possibilities exist. Here’s a quick rundown:

Dead Key Fob Battery: The most frequent reason. Key fob batteries have a limited lifespan, and a depleted one won’t have the juice to transmit signals.
Key Fob Programming Issues: Sometimes, the key fob might lose its programming with the vehicle, requiring reprogramming by a dealer or a qualified locksmith.
Signal Interference: Strong radio signals from other devices or structures might temporarily disrupt the communication between your key fob and the truck.
Internal Key Fob Damage: Physical damage from drops or water exposure could render your key fob unusable.

If a simple battery replacement doesn’t resolve the issue, it’s best to consult a professional for further diagnosis.

What You’ll Need to Change the Battery

Don’t worry; you won’t need a mechanic’s toolbox for this task. Here’s what you’ll need:

A fresh CR2032 battery: These are readily available online or at your local auto parts store.
A small flathead screwdriver: This will help you pry open the key fob casing.

Changing the Battery: A Step-by-Step Guide

Ready to bring your Silverado key fob back to life? Let’s get started:

Locate the key release button on the back of your key fob.
Press the button and gently slide out the metal key.
Identify the small slot on the side of the key fob. This is where you’ll insert the flathead screwdriver.
Carefully insert the screwdriver and gently pry open the casing. Be careful not to apply excessive force to avoid damage.
Once open, locate the CR2032 battery. It’s usually secured in a small compartment.
Gently pry out the old battery and replace it with the new one. Ensure the positive (+) side of the battery faces upwards.
Align the key fob casing halves and press them firmly together until they snap shut.
Reinsert the metal key into its slot.
Test the key fob by pressing its buttons. If everything works as expected, you’ve successfully replaced the battery.

Still Having Issues?

If your Silverado key fob remains unresponsive after changing the battery, don’t despair. Here are some additional tips:

Check Battery Placement: Ensure the new battery is correctly positioned with the positive (+) side facing up.
Inspect the Battery Contacts: Look for any dirt, debris, or corrosion on the battery contacts inside the key fob. Clean them gently with a cotton swab and rubbing alcohol if needed.
Reprogram the Key Fob: In some cases, you might need to reprogram the key fob to your vehicle. Consult your owner’s manual or contact a Chevrolet dealership for guidance.
