A dead key fob battery can leave you stranded. Luckily, replacing the battery in your Tesla key fob is a simple process that can be done at home in minutes. This guide will walk you through the steps and get you back on the road in no time.
What You’ll Need
You only need a few things to change your Tesla key fob battery:
- A new CR2032 battery (you can find these at most grocery stores and pharmacies)
- A small flathead screwdriver
How to Replace the Battery
Step 1: Open the Key Fob
Locate the small release button on the bottom of the key fob. It’s on the side with the Tesla logo, near where the key blade comes out. While pressing the button, gently slide the cover away from the rest of the fob.
Step 2: Remove the Old Battery
With the key fob open, you’ll see the CR2032 battery nestled inside. Carefully pry out the old battery using your flathead screwdriver. Be gentle to avoid damaging the fob’s internal components.
Step 3: Install the New Battery
Insert the new CR2032 battery into the fob, making sure the positive (+) side faces up. You should hear a satisfying click when it’s properly seated.
Step 4: Reassemble the Key Fob
Align the back cover with the key fob body and slide it back into place. You should feel it click securely shut.
Testing Your New Battery
Once the key fob is back together, test it by trying to lock and unlock your car. If it doesn’t work, double-check that the battery is properly installed and that the positive side is facing up.
Troubleshooting Tips
Still having trouble? Here are a few things to check:
- Battery Type: Ensure you’re using a CR2032 battery. Other types won’t fit or function correctly.
- Battery Orientation: The positive (+) side of the battery must face upward for the fob to work.
- Clean Contacts: Over time, the battery contacts in the fob can become dirty or corroded. Gently clean them with a cotton swab and rubbing alcohol if needed.
