As technology continues to advance, key fobs have become an essential accessory for car owners. Tesla, the leading electric car manufacturer, has also embraced this trend with their innovative key fobs. However, just like any other battery-powered device, the battery in your Tesla key fob will eventually need to be replaced. In this article, we will guide you through the process of replacing the Tesla key fob battery in 2023.

Step 1: Determine the Type of Key Fob

Before getting started, it is crucial to identify which type of Tesla key fob you own. Tesla introduced a new key fob design in 2021, so it is important to ensure you have the correct instructions for your specific key fob model.

Step 2: Gather the Necessary Tools

Replacing the Tesla key fob battery is a relatively simple task that requires a few basic tools. To complete the process, you will need a small flathead screwdriver, a replacement CR2032 battery, and a clean cloth.

Step 3: Prepare a Clean Work Area

Find a clean, well-lit area to work on your key fob. This will prevent any small components from getting lost and make the process more convenient for you.

Step 4: Open the Tesla Key Fob

Using the small flathead screwdriver, carefully pry open the Tesla key fob. Start at one corner and gently work your way around until the two halves of the key fob separate. Be cautious not to apply excessive force, as this could damage the key fob or its components.

Step 5: Remove the Old Battery

Once the key fob is open, you will see the battery compartment. Use the flathead screwdriver to carefully lift the old battery out of its slot. Take note of the battery’s orientation, as you will need to place the new battery in the same position.

Step 6: Insert the New Battery

Take the replacement CR2032 battery and align it correctly in the battery compartment. Ensure that the positive side of the battery is facing up, as indicated by the markings in the key fob.

Step 7: Close the Key Fob

Gently press the two halves of the key fob together until they snap back into place. Make sure all the edges are aligned properly to ensure a secure fit.

Step 8: Test the Key Fob

Press any button on the key fob to ensure it is working correctly. If the key fob does not respond, double-check that the battery is inserted correctly and that the two halves of the key fob are securely closed.

Step 9: Clean the Key Fob

Before using your Tesla key fob, take a clean cloth and gently wipe away any fingerprints or smudges on the surface. This will help maintain its appearance and prevent any potential damage.


By following these simple steps, you can easily replace the battery in your Tesla key fob and ensure it continues to function optimally. Remember to use the correct tools, work in a clean environment, and pay attention to the battery’s orientation. With a little care, your Tesla key fob will be ready to unlock and start your electric vehicle for many more adventures.
