Tesla key fobs are designed for convenience, allowing you to seamlessly access and control your vehicle. Like any electronic device, the key fob relies on a battery to function. Typically, a Tesla key fob battery will last up to a year under normal use, although this can vary depending on the specific key fob version and your vehicle’s settings. When the battery begins to weaken, your Tesla touchscreen will display a message alerting you to the low battery level. Replacing the battery in your Tesla key fob is a straightforward process that you can easily do yourself. This guide will walk you through each step, ensuring you can quickly and safely get your key fob back in working order.
Understanding Your Tesla Key Fob Battery
Your Tesla key fob is powered by a common and readily available coin cell battery, specifically the CR2032 type. This type of battery is known for its longevity and reliability, contributing to the typical one-year lifespan of your key fob battery. It’s important to be aware of the low battery notification on your Tesla’s touchscreen. This message is your signal that the key fob battery is nearing the end of its life and should be replaced soon to avoid any inconvenience. Keeping a spare CR2032 battery on hand can be a proactive measure to ensure you’re prepared when the low battery warning appears.
Step-by-Step Guide to Replacing Your Tesla Key Fob Battery
Replacing the battery in your Tesla key fob is a simple task that requires minimal tools and time. Follow these steps carefully to ensure a smooth and successful battery replacement.
Step 1: Prepare Your Tools and Workspace
Before you begin, gather the necessary tools. You will need a small, flat-bladed tool, such as a small screwdriver or a plastic trim removal tool. A soft surface is also recommended to protect your key fob from scratches during the battery replacement process. A clean cloth or a soft mat will work perfectly. Ensure you have a new CR2032 battery ready for installation. You can purchase these batteries from most retailers that sell batteries, including drugstores, supermarkets, and online retailers.
Step 2: Open the Key Fob Casing
Place your Tesla key fob button side down on your prepared soft surface. Locate the bottom cover of the key fob. Using your small flat-bladed tool, gently insert the tool into the seam where the bottom cover meets the rest of the key fob casing. Carefully pry the bottom cover loose. It should release with a gentle amount of pressure. Avoid using 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 compartment. The CR2032 battery is held in place by retaining clips. Gently lift the battery to disengage it from these clips. You may need to use your flat-bladed tool to carefully nudge the battery if it’s held in tightly. Remove the old battery from the compartment.
Step 4: Insert the New CR2032 Battery
Take your new CR2032 battery and note the ‘+’ symbol indicating the positive side. It is crucial to insert the new battery with the ‘+’ side facing up. Before inserting the new battery, it’s advisable to wipe it clean with a lint-free cloth to remove any fingerprints. Avoid touching the flat surfaces of the battery with your fingers as much as possible. Fingerprints can leave oils that may reduce battery life. Carefully slide the new battery into the battery compartment, ensuring it is securely placed under the retaining clips.
Step 5: Reassemble the Key Fob
With the new battery in place, it’s time to reassemble 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 body. Once aligned, press the cover firmly onto the key fob until it snaps securely into place. You should hear or feel a click indicating that the cover is properly closed and locked.
Step 6: Test Your Key Fob
After reassembling the key fob, test its functionality to ensure the battery replacement was successful. Go to your Tesla Model 3 and attempt to unlock and lock the vehicle using the key fob. If the car responds as expected, then the battery replacement is complete, and your key fob is working correctly. If you encounter any issues, re-check that the battery is correctly installed with the ‘+’ side up and that the key fob cover is securely snapped into place.
Important Safety Warnings
It is crucial to handle key fob batteries with care and be aware of potential safety hazards. Tesla key fob batteries, like other coin cell batteries, contain chemicals that can cause burns if ingested. These batteries pose a serious risk, especially to children.
Warning: Key fob batteries are a chemical burn hazard and must not be swallowed. The key fob contains a coin cell battery. If a coin cell battery is swallowed, it can cause severe internal burns within just two hours and can be fatal.
Always keep both new and used batteries out of the reach of children. Ensure that the battery compartment of the key fob is securely closed after replacing the battery. If the compartment does not close properly, stop using the key fob and keep it away from children. In the event that you suspect a battery may have been swallowed or placed inside any part of the body, seek immediate medical attention. Prompt medical care is essential in such situations.
Conclusion
Replacing the battery in your Tesla key fob is a simple maintenance task that every Tesla owner can perform. By following these step-by-step instructions, you can ensure your key fob remains functional and reliable. Remember to always prioritize safety by handling batteries with care and keeping them away from children. With a fresh CR2032 battery, your Tesla key fob will be ready to provide seamless access and control of your vehicle for another year.
