But in this article, we will try our best to help you always carry a spare key battery in your car so you can avoid being stranded. Also, we are providing you with detailed steps on how to change the battery in your Chevy key fob. We will also give you some tips on how to prevent your key fob battery from dying in the first place.

The key fob in your Chevy is responsible for locking and unlocking the doors, opening the trunk, and starting the engine. It is a small, battery-operated device that uses a radio frequency to communicate with your car. Over time, the battery in your key fob will eventually die and need to be replaced. Knowing how to change the battery in your Chevy key fob is a simple task that can be done in just a few minutes. However, if you are not comfortable doing it, you can always take it to a dealership or locksmith.

Here are the steps on how to change the battery in your Chevy key fob:
1. First, find where the battery is located. On most Chevy key fobs, the battery is located under a small, rubber cover on the back of the fob.
2. Use a small screwdriver or other pointed object to pry open the cover.
3. Once the cover is open, you will see the battery. It is usually a small, round battery.
4. Use your fingernail or a pair of tweezers to remove the battery from the fob.
5. Insert the new battery into the fob, making sure that the positive side of the battery is facing up.
6. Replace the cover and press it down until it snaps into place.

Recognizing a Low Battery Warning

Chevy key fobs typically display several telltale signs when their batteries are running low. Recognizing these warnings is crucial to ensure the smooth operation of your vehicle. Here’s a detailed look at the most common indicators:

Dim or Intermittent Lights: The key fob’s buttons may start emitting fainter or intermittent lights as the battery weakens. This is a clear indication that the battery is nearing its end and needs to be replaced.
Reduced Remote Signal Range: The range at which you can operate your vehicle remotely using the key fob may decrease significantly. You may notice that you have to move closer to the car or press the buttons multiple times to unlock or start the engine.
Slow or No Response: As the battery further depletes, the key fob may respond slowly or not at all when you press the buttons. It may fail to lock, unlock, or start the car altogether, leaving you stranded.
Dash Warning Light: Some Chevy models have a dash warning light that illuminates when the key fob battery is low. This light typically features a symbol resembling a key or a battery, alerting you to the need for a replacement.
Chiming Sound: As the battery nears its critical point, your vehicle may emit a distinctive chime or series of beeps when you attempt to start the engine. This audible warning serves as a final indication that the key fob battery needs immediate attention.

Symptom	Possible Cause
Dim or intermittent lights	Low battery
Reduced remote signal range	Low battery, interference
Slow or no response	Low battery, fob damage
Dash warning light	Low battery
Chiming sound	Critical battery level

Identifying the Correct Battery Type

Determining the appropriate battery type for your Chevy key fob is crucial. Refer to your vehicle’s owner’s manual or search online using the key fob’s model number. This information can also be obtained from a local auto parts store. The table below lists common battery types used in Chevy key fobs:

Key Fob Model	Battery Type
GM 15956551 / 15279118	CR2032
GM 15795067	CR2025
GM 15921893	CR2016

It’s essential to note that using the correct battery type is vital for the proper functioning of your key fob. Incorrect battery installation or the use of incompatible battery types can damage the fob or cause malfunction.

Gathering Essential Tools

Before embarking on the key fob battery replacement task, it is essential to assemble the necessary tools. This will not only ensure a hassle-free and efficient process but also prevent any damage to the key fob or its components.

Tools Required:

Tool	Description
Phillips screwdriver	For removing the key fob cover
Flat-head screwdriver	For prying open the key fob cover (optional)
Precision tweezers (optional)	For retrieving the old battery or inserting the new one
New CR2032 battery	Replacement battery for the key fob

Specific Tips for Finding the Right Screwdriver:

The type of Phillips screwdriver required will vary depending on the make and model of your Chevy vehicle. It is recommended to consult your vehicle’s owner’s manual or refer to online resources to determine the exact size and type of screwdriver needed. Using the wrong size or type of screwdriver could damage the key fob’s screws or cover.

If you do not have a Phillips screwdriver, you can purchase one from any hardware store or automotive supply store. Make sure to choose a screwdriver with a good grip and a magnetic tip to hold the screw securely while tightening or loosening it.

Locating the Key Fob Battery Compartment

Depending on the model and year of your Chevrolet vehicle, the key fob battery compartment can be found in various locations:

Option 1: If your key fob has a physical key, the battery compartment is typically located on the back or side of the key fob. Gently pull or slide the back panel of the key fob to expose the battery.

Option 2: For key fobs without a physical key, the battery compartment may be accessed through a small door or cover. Locate the door or cover on the side or bottom of the key fob and use a small tool (such as a flathead screwdriver or paperclip) to carefully pry it open.

Option 3: In some Chevrolet models, the key fob battery compartment is integrated into the interior of the key fob. To access the battery, you may need to remove the key fob’s back cover by unscrewing a small screw or lifting a latch.

Checking the Battery Type

Once you have located the key fob battery compartment, inspect the installed battery to determine its type. Common battery types used in Chevrolet key fobs include CR2032, CR2025, and CR2016. Check the table below for your specific model:

Chevrolet Model	Key Fob Battery Type
Chevy Suburban (2015-2023)	CR2032
Chevy Silverado (2019-2023)	CR2025
Chevy Malibu (2016-2023)	CR2016

Note that the battery type may vary depending on the specific year and trim level of your Chevrolet. Refer to your vehicle’s owner’s manual for confirmation.

Removing the Old Battery

To remove the old battery, follow these steps:

Turn the key fob over and locate the small screw on the back.
Using a small Phillips-head screwdriver, carefully unscrew the screw.
Gently pry open the key fob using a flathead screwdriver or your fingernail.
Locate the battery, which is usually held in place by a small metal clip or spring.
Carefully remove the battery by pressing down on the clip or spring and lifting the battery out. Note the orientation of the battery so that you can insert the new battery correctly.

In some cases, the battery may be soldered in place. If this is the case, you will need to use a soldering iron to remove the old battery and solder in the new battery.

Inserting the New Battery Properly

Once you have the new battery, it’s time to insert it into the key fob. To do this, follow these steps:

Hold the key fob upside down and locate the small release button on the back. Press the button and the key fob should pop open.
Carefully remove the old battery and insert the new battery with the positive (+) side facing up.
Close the key fob and press the button to snap it shut.
Check if the key fob is working properly by pressing the buttons and seeing if the lights flash.

Here are some additional tips for inserting the new battery properly:

* Make sure that the battery is the correct size and type for your key fob.
* Handle the battery with care and avoid touching the terminals.
* Insert the battery with the correct polarity. The positive (+) side of the battery should face up.
* Close the key fob securely to prevent the battery from falling out.
* If the key fob is still not working properly, try replacing the battery again.

Aligning the Compartment Lid

Once the battery compartment is exposed, you’ll need to carefully align the lid before closing it. Here are the steps to do this:

Inspect the lid: Examine the lid’s edges and make sure there are no cracks, breaks, or any visible damage that could compromise its fit.
Identify alignment tabs: Locate the small tabs or grooves on the lid and the corresponding slots on the key fob body. These alignment tabs ensure that the lid fits correctly and securely.
Align the tabs: Carefully slide the lid back into place, ensuring that the alignment tabs on the lid match and align with the slots on the key fob.
Apply gentle pressure: Use light and even pressure to push down on the lid until it clicks into place. Avoid applying excessive force, as this could damage the lid or the alignment tabs.
Check the alignment: Once the lid is closed, gently shake or wiggle the key fob to ensure that it’s securely shut and that the battery compartment is not loose.
Test the key fob: Press a button on the key fob to test its functionality. If the key fob functions normally, the battery compartment lid has been aligned and closed correctly.
Inspect the lid periodically: Over time, due to wear and tear, the alignment of the battery compartment lid may become compromised. Regularly inspect the lid to ensure it’s properly aligned and closed, preventing moisture or debris from entering the battery compartment.

Reattaching the Compartment Lid

1. Align the lid correctly. Make sure that the lid is positioned correctly on the compartment. The lid may have a notch or groove that must align with a corresponding ridge or slot on the compartment.

2. Press the lid down firmly. Use your thumb or finger to press down on the lid with even pressure. Start from one corner and work your way around the perimeter of the lid, ensuring that it snaps into place securely.

3. Test the lid. Close the lid completely and press the release button to ensure that it opens smoothly. If the lid does not open or close properly, check to make sure that it is properly aligned and snapped into place.

4. Clean the battery compartment. Use a clean cloth or cotton swab to wipe away any dirt or debris that may have accumulated in the battery compartment. This will help prevent corrosion and ensure that the new battery makes good contact with the terminals.

5. Inspect the key fob. Take a moment to inspect the key fob for any signs of damage, such as cracks, broken buttons, or loose wires. If you notice any issues, contact a qualified locksmith or automotive technician for assistance.

6. Reassemble the key fob. Once the battery compartment lid is securely attached, reassemble the key fob by snapping the two halves together. Ensure that the key blade is folded into the fob for storage.

7. Test the key fob. Press the buttons on the key fob to ensure that they are functioning properly. If any of the buttons are not working, double-check the battery connections or consult a qualified locksmith or automotive technician.

8. Replacement battery life. The lifespan of a key fob battery varies depending on factors such as usage, environmental conditions, and battery quality. Generally, a new battery should last for several months to a year before needing to be replaced. It is recommended to replace the battery regularly to prevent any unexpected key fob failures.

CR2025	6-12
CR2032	8-18
CR2016	4-8

Testing the Key Fob Functionality
