Experiencing issues with your Tesla key fob? Like any battery-powered device, the Tesla key fob relies on a battery to function, and eventually, it will need replacing. Typically, under normal usage, you can expect your key fob battery to last up to a year. The lifespan can vary depending on the specific key fob version and your Tesla vehicle’s settings. When the battery begins to weaken, your Tesla’s touchscreen will display a message alerting you to the low battery. Replacing the battery is a straightforward process that you can easily do yourself. This guide will walk you through the steps for a quick and efficient Tesla key fob battery replacement.
When to Replace Your Tesla Key Fob Battery
Your Tesla will notify you on the touchscreen when your key fob battery is running low. This is your primary indicator. However, you might also notice other signs, such as the key fob becoming less responsive, requiring you to be closer to your vehicle to unlock or lock it. Don’t wait until your key fob completely stops working. Addressing the low battery warning promptly will ensure you’re never caught off guard.
Step-by-Step Guide to Tesla Key Fob Battery Replacement
Replacing the battery in your Tesla key fob is a simple task that requires minimal tools. Follow these steps to get your key fob working like new again:
Tools You’ll Need
- A small flat-bladed tool (like a small screwdriver or plastic pry tool)
- A new CR2032 battery
Step 1: Open the Key Fob
Place your Tesla key fob button side down on a soft, clean surface to prevent scratches. Locate the bottom cover of the key fob. Use your small flat-bladed tool to gently release the bottom cover. Insert the tool into the seam and carefully pry it open. The cover should detach relatively easily.
Step 2: Remove the Old Battery
Once the cover is removed, you’ll see the battery. The battery is held in place by retaining clips. Carefully lift the old battery out of its compartment, ensuring you detach it from these clips.
Step 3: Install the New Battery
Take your new CR2032 battery. It’s important to insert it correctly. Ensure the ‘+’ side of the battery is facing upwards as you place it into the compartment. Before inserting, wipe the new battery clean to remove any fingerprints, as finger oils can reduce battery life. Avoid touching the flat surfaces as much as possible.
Step 4: Close the Key Fob and Test
Hold the bottom cover at a slight angle and align the tabs on the cover with the corresponding slots on the key fob. Press the cover firmly until it snaps securely back into place. You should hear a click indicating it’s properly closed. Finally, test your key fob by attempting to unlock and lock your Tesla to ensure it’s working correctly with the new battery.
Important Safety Warnings
Tesla key fobs use CR2032 coin cell batteries. These batteries pose a chemical burn hazard if ingested. Warning: Coin cell batteries are dangerous and must be kept away from children at all times. Swallowing a coin cell battery can cause serious internal burns within just two hours and can be fatal. Always keep both new and used batteries out of reach of children. If the battery compartment doesn’t close securely after replacement, discontinue use of the key fob and keep it away from children. If you suspect a battery has been swallowed or placed inside any part of the body, seek immediate medical attention.
Conclusion
Replacing your Tesla key fob battery is a quick and easy maintenance task that every Tesla owner can perform. By following these simple steps, you can ensure your key fob remains functional and reliable. Remember to always handle batteries with care and heed the safety warnings to prevent any accidents. With a fresh battery, your Tesla key fob will be ready to provide seamless access and control of your vehicle for another year.
