Is your Tesla key fob not working as reliably as it used to? You might be experiencing a low battery. Like any electronic device, the Tesla key fob relies on a battery to function, and eventually, this battery will need replacing. Fortunately, changing the battery in your Tesla key fob is a straightforward process you can easily do yourself at home. This guide will walk you through each step to replace your Tesla key fob battery, ensuring you can regain seamless access to your vehicle.
When to Replace Your Tesla Key Fob Battery
Tesla key fobs are designed to have a battery life of approximately one year under normal use. This duration can vary based on the specific key fob version you have and your vehicle settings. Your Tesla touchscreen will typically display a message indicating “key fob battery is low” when it’s time for a replacement. Don’t wait until your key fob completely stops working. Replacing the battery proactively when you see this warning can prevent any inconvenience.
What You’ll Need
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 drug stores, supermarkets, and online retailers.
- Small Flat-Bladed Tool: A small screwdriver or a similar flat tool will help you gently open the key fob casing.
Step-by-Step Tesla Key Fob Battery Replacement
Follow these steps to replace your Tesla key fob battery quickly and efficiently:
Step 1: Open the Key Fob
Place your Tesla key fob button side down on a soft, clean surface to protect it from scratches. Locate the bottom cover of the key fob. Using your small flat-bladed tool, carefully insert the tool into the seam where the bottom cover meets the main body of the key fob. Gently pry to release the bottom cover. It should pop open with minimal effort.
Step 2: Remove the Old Battery
Once the bottom cover is removed, you’ll see the battery. The battery is held in place by retaining clips. Carefully lift the battery to disengage it from these clips and remove it from the key fob.
Step 3: Insert the New Battery
Take your new CR2032 battery. It’s crucial to insert it with the ‘+’ side facing upwards. Before installing the new battery, it’s a good practice to wipe it clean to remove any fingerprints. Avoid touching the flat surfaces of the battery as much as possible, as oils from your fingers can shorten the battery’s lifespan. Slide the new battery into position, ensuring it’s securely held by the retaining clips.
Step 4: Close the Key Fob
Take the bottom cover and hold it at a slight angle. Align the tabs on the cover with the corresponding slots on the key fob body. Press the cover firmly onto the key fob until you hear or feel it snap securely into place. Ensure that the cover is fully closed and flush with the rest of the key fob casing.
Step 5: Test Your Key Fob
After reassembling the key fob, test it immediately to ensure it’s working correctly. Try unlocking and locking your Tesla Model 3 or other Tesla model to confirm the new battery is functioning and the key fob is communicating with your vehicle.
Important Safety Warning
It is critical to remember that key fob batteries pose a chemical burn hazard if ingested. Tesla key fobs contain a coin cell battery. If swallowed, this type of battery can cause severe internal burns within just two hours and can be fatal. Always keep new and used batteries out of reach of children. If the battery compartment of your key fob does not close securely, stop using it and keep it away from children. In case you suspect that a battery has been swallowed or placed inside any part of the body, seek immediate medical attention.
Replacing your Tesla key fob battery is a simple maintenance task that every Tesla owner can handle. By following these steps, you can ensure your key fob remains powered and reliable, providing you with seamless access to your Tesla vehicle.
