Keeping your Buick Enclave key fob battery in good condition is crucial to ensure smooth and hassle-free operation of your vehicle. In this article, we will provide you with a step-by-step guide on how to replace the key fob battery for your Buick Enclave, saving you time and money.

Step 1: Determine the Correct Battery

The first step is to determine the correct battery for your Buick Enclave key fob. You can find this information in your vehicle’s owner manual or by contacting your local Buick dealership. Make sure to note down the battery model number and voltage for reference.

Step 2: Gather the Required Tools

Before starting the battery replacement process, gather all the necessary tools. You will need a small flathead screwdriver or a pry tool to open the key fob, and a new battery that matches the specifications of your Buick Enclave key fob.

Step 3: Open the Key Fob

Using the flathead screwdriver or pry tool, gently pry open the key fob. Start from the small gap between the two halves of the key fob and carefully work your way around to avoid damaging the casing. Once the key fob is open, set aside the back cover.

Step 4: Remove the Old Battery

Locate the battery inside the key fob. It is usually a small round battery that is easily visible. Carefully remove the old battery using your fingers or a small tool. Take note of the battery’s polarity (+ and -) to ensure proper installation of the new battery.

Step 5: Install the New Battery

Take the new battery and align it with the battery compartment in the key fob. Ensure that the polarity matches the markings inside the key fob. Gently press the battery into place until it is secure.

Step 6: Close the Key Fob

With the new battery installed, carefully align the back cover of the key fob with the front half. Press the two halves together until they click into place. Make sure the key fob is properly sealed to prevent any water or dust from entering.

Step 7: Test the Key Fob

Now that the key fob is back together, it’s time to test it. Stand near your vehicle and press the buttons on the key fob to ensure that it is working properly. If the key fob is not functioning correctly, double-check the battery installation and try again.

Step 8: Dispose of the Old Battery

Properly dispose of the old battery in accordance with local regulations. Many electronic stores and recycling centers accept used batteries for recycling. Do not throw the old battery in the regular trash as it can be harmful to the environment.

Step 9: Battery Life and Replacement Frequency

It is recommended to replace the battery in your Buick Enclave key fob every 1-2 years, depending on usage. Regularly check the battery’s voltage to ensure it is functioning correctly. If you notice a decrease in the key fob’s range or responsiveness, it may be time to replace the battery.


Replacing the battery in your Buick Enclave key fob is a simple and straightforward process that can save you time and money. By following the steps outlined in this guide, you can ensure that your key fob remains in optimal condition, providing you with convenient access to your vehicle.
