Is your Tesla key fob displaying a low battery warning on your touchscreen? Don’t worry, replacing the battery is a straightforward process you can easily do yourself. This guide will walk you through each step to change your Tesla key fob battery, ensuring you stay on the road without interruption. Knowing how to perform this simple maintenance task is essential for every Tesla owner, saving you time and a trip to the service center.
What You’ll Need to Change Your Tesla Key Fob Battery
Before you begin, gather these simple tools:
- New CR2032 Battery: This is the standard coin cell battery required for Tesla key fobs. You can purchase these at most drugstores, supermarkets, and online retailers.
- Small Flat-Bladed Tool or Soft Cloth Wrapped Tool: A small screwdriver or even a plastic trim removal tool will work. If using a screwdriver, wrap the tip in a soft cloth to prevent scratches on your key fob.
- Soft Surface: A cloth or soft mat to protect your key fob during the battery replacement.
Step-by-Step Guide to Changing Your Tesla Key Fob Battery
Follow these easy steps to replace the battery in your Tesla key fob:
Step 1: Prepare Your Key Fob
Place your Tesla key fob button side down on a soft surface. This will protect the buttons and the surface of your key fob from scratches during the battery replacement process. Ensure you are working in a clean and well-lit area.
Step 2: Open the Key Fob
Locate the bottom cover of your key fob. Using your small flat-bladed tool (or cloth-wrapped tool), gently pry open the bottom cover. Insert the tool into the small slot located on the side of the key fob, near the bottom. Apply gentle pressure to release the cover. You should hear a click or feel the cover slightly loosen. Be careful not to apply excessive force, as this could damage the key fob casing.
Step 3: Remove the Old Battery
Once the bottom cover is released, you will see the battery. The battery is held in place by retaining clips. Carefully lift the old battery away from these clips to remove it. You can use your fingertip or the edge of your tool to gently nudge the battery free. Take note of the battery orientation – specifically, which side is facing up. Usually, the positive (+) side is facing upwards.
Step 4: Insert the New Battery
Take your new CR2032 battery and ensure the positive (+) side is facing upwards, matching the orientation of the old battery you just removed. Slide the new battery into place, pressing it gently until it is securely held by the retaining clips. Important: Before inserting the new battery, wipe it clean with a soft, dry cloth to remove any fingerprints. Avoid touching the flat surfaces of the battery with your fingers, as oils from your skin can reduce battery life.
Step 5: Close the Key Fob
Hold the bottom cover at a slight angle and align the tabs on the cover with the corresponding slots on the key fob. Once aligned, press the cover firmly onto the key fob until it snaps securely into place. You should hear a distinct click, indicating that the cover is properly closed and locked. Ensure there are no gaps and the cover is flush with the rest of the key fob casing.
Step 6: Test Your Key Fob
After reassembling the key fob, test its functionality immediately. Unlock and then lock your Tesla Model 3 (or other Tesla model) using the key fob buttons. If the car responds as expected, you have successfully changed the Tesla key fob battery. If you encounter any issues, double-check that the battery is correctly installed and the key fob is properly closed.
Important Warnings and Tips
- Battery Safety: Tesla key fobs use CR2032 coin cell batteries, which can be dangerous if swallowed. These batteries contain chemicals that can cause serious internal burns within just two hours and can be fatal. Keep both new and used batteries away from children.
- Seek Medical Attention: If you suspect a battery has been swallowed or placed inside any part of the body, seek immediate medical attention.
- Secure Battery Compartment: Ensure the battery compartment closes securely after replacement. If it doesn’t close properly, stop using the key fob and keep it away from children.
- Battery Life: Under normal use, a Tesla key fob battery typically lasts up to a year. Battery life can vary depending on key fob version, vehicle settings, and usage patterns.
- Low Battery Message: When your key fob battery is low, a message will appear on your Tesla touchscreen to alert you. Replace the battery promptly when you see this warning to avoid inconvenience.
By following these simple steps, you can easily change your Tesla key fob battery and ensure your key fob remains functional. This simple DIY task can save you time and keep you on the move.
