Replacing a Chevy key fob battery is a simple task that can be completed in just a few minutes. Here’s a step-by-step guide to help you get the job done quickly and easily.
First, you’ll need to gather a few tools. You’ll need a small Phillips head screwdriver, a new battery (CR2032), and a soft cloth or paper towel. Once you have your tools gathered, you can begin the replacement process. Start by removing the screw from the back of the key fob. Once the screw is removed, gently pry open the two halves of the key fob. Be careful not to damage the circuit board inside. Once the key fob is open, you’ll see the battery. Use the soft cloth or paper towel to remove the old battery and insert the new one. Make sure that the positive (+) side of the battery is facing up. Once the new battery is in place, close the two halves of the key fob and replace the screw.
Your key fob is now ready to use. If you have any trouble replacing the battery, consult your vehicle’s owner’s manual or contact a qualified mechanic for assistance.
Identifying the Key Fob’s Battery Compartment
Locating the battery compartment in your Chevy key fob is a crucial step before you can proceed with the replacement process. This compartment is typically hidden within the fob’s casing, and its location can vary depending on your specific key fob model.
To find the battery compartment, you’ll need to carefully examine the key fob’s exterior for any visible seams or openings. These seams often indicate where the fob can be opened to reveal the battery compartment. Using a small, flathead screwdriver or a key, gently pry open the seam to expose the compartment.
In some cases, the battery compartment may be secured with a small screw or latch. If you encounter a screw, use an appropriate screwdriver to remove it and gain access to the battery compartment. If the compartment is secured with a latch, simply slide or press the latch to release and open it.
| Key Fob Model | Battery Compartment Location |
|---|---|
| Chevy Silverado (2014-2018) | Bottom of the key fob, under a small plastic cover |
| Chevy Malibu (2016-2019) | Back of the key fob, under a small rubber flap |
| Chevy Equinox (2017-2021) | Inside the key fob, accessible by removing the rear panel |
Locating the Correct Replacement Battery
Identifying the appropriate replacement battery for your Chevy key fob is crucial. Refer to the owner’s manual or consult with your local dealership for the recommended battery type and specifications. Additionally, you can utilize online resources or visit auto parts stores to determine the correct battery.
Here’s a table summarizing key aspects to consider when selecting a replacement battery:

If you encounter difficulties closing the battery compartment, consider the following troubleshooting tips:
| Issue | Solution |
|---|---|
| Cover does not snap into place | Ensure that the battery is securely seated in the compartment and that the cover is properly aligned. |
| Key fob does not work | Reopen the battery compartment, inspect the battery contacts, and ensure that they are free of debris or damage. |
| Cover is loose or rattling | Tighten the screws on the back of the key fob (if applicable) or replace the battery cover if it is damaged. |
Testing the Key Fob’s Functionality
It is crucial to check the functionality of your key fob before replacing its battery. This will help you determine if the issue stems from the fob itself or the battery. Follow these steps to test the key fob:
1. Press the lock button on the remote. Observe if the vehicle’s doors lock and the lock indicator lights flash.
2. Next, press the unlock button. Verify if the doors unlock and the unlock indicator lights illuminate.
3. Move closer to the vehicle and press the remote start button. Check if the vehicle’s engine starts successfully.
4. If any of these functions fail to work, repeat the test closer to the vehicle to rule out signal strength issues.
5. If the key fob still malfunctions, try using a spare key fob if you have one. This will help you isolate the issue to the specific key fob or a more significant problem with the vehicle’s keyless entry system.
6. If all of the above tests fail, it is likely that the battery in the key fob needs to be replaced. Follow the steps in the next section to replace the key fob battery.

Troubleshooting Common Key Fob Battery Issues
Battery Isn’t Making Contact
If your key fob battery isn’t making contact with the terminals, it won’t be able to power the device. Try bending the metal contacts on the battery slightly to ensure a better connection.
Battery Is Weak
Even if the battery is making contact, it may be too weak to power the key fob. Replace the battery with a new one of the same voltage and type.
Battery Orientation
Make sure the battery is inserted correctly, with the positive (+) side facing up and the negative (-) side facing down. Incorrect orientation can prevent the battery from working.
Broken Battery Terminal
If one of the battery terminals is broken or bent, it may not be able to make contact with the battery. Inspect the battery terminals and replace the battery if necessary.
Corroded Battery Terminals
Over time, battery terminals can become corroded, preventing proper contact. Clean the terminals with rubbing alcohol and a cotton swab to remove any corrosion.
Faulty Key Fob
If you’ve tried all of the above steps and the key fob still isn’t working, the problem may be with the key fob itself. You may need to replace the entire key fob or take it to a technician for repair.
Weak Key Fob Signal
If the key fob signal is weak, it may not be able to reach the vehicle’s receiver. Try moving closer to the vehicle or replacing the key fob battery.
Replacing Chevy Key Fob Battery
1. Locate the key release button on the back of your key fob. It may be a small button with a key symbol or a lever.
2. Press the release button and pull the emergency key out.
3. Use a small flathead screwdriver or a coin to gently pry open the back cover of the key fob.
4. Remove the old battery and replace it with a new battery of the same type. Make sure the positive (+) side of the battery is facing up.
5. Snap the back cover back into place.
6. Test the key fob to make sure it is working properly.
Extending the Key Fob Battery’s Lifespan
9. Avoid Extreme Temperatures
Extreme temperatures can significantly affect the lifespan of the key fob battery. Avoid exposing the key fob to very hot or cold environments for extended periods of time. If you must store the key fob in a hot or cold environment, try to keep it in a temperature-controlled area.
This is especially important when storing the key fob in a car during the summer or winter. Temperatures inside a closed car can reach extreme highs and lows, which can shorten the battery’s lifespan.
To extend the battery’s lifespan, store the key fob in a cool, dry place that is not exposed to direct sunlight or extreme temperatures.
