Like any electronic device, your Tesla Model S key fob relies on a battery to function. Typically, this battery will last about a year with normal use, although this can vary depending on your usage habits and vehicle settings. When the battery starts to get low, your Model S touchscreen will display a message alerting you to this. Replacing the key fob battery in your Tesla Model S is a straightforward process that you can easily do yourself. This guide will walk you through each step.
Understanding When to Replace Your Key Fob Battery
Before diving into the replacement process, it’s helpful to understand when you’ll need to change your Tesla Model S Key Fob Battery. Tesla vehicles are designed to notify you when the key fob battery is running low. You’ll typically see a warning message appear on your touchscreen. Besides this warning, you might also notice:
- Reduced Range: You may need to be closer to your Model S for the key fob to lock or unlock the doors.
- Inconsistent Operation: The buttons on your key fob might become less responsive, requiring multiple presses.
- Complete Failure: In the most obvious case, the key fob will simply stop working altogether.
These signs indicate it’s time for a battery replacement to ensure seamless access and operation of your Tesla Model S.
What You’ll Need for the Replacement
Fortunately, replacing the Tesla Model S key fob battery requires minimal tools. Here’s what you’ll need:
- New CR2330 Battery: This is the specific type of battery required for the Tesla Model S key fob. You can purchase these batteries at most retailers that sell batteries, including drugstores, supermarkets, and online marketplaces.
- Small Flat-Bladed Tool: A small screwdriver or a similar flat tool will be needed to gently pry open the key fob cover.
- Soft Cloth or Surface: Having a soft surface to work on will prevent scratches to your key fob during the battery replacement process.
Step-by-Step Guide to Replacing the Battery
Now, let’s get to the battery replacement process. Follow these steps carefully:
-
Prepare the Key Fob: Place your Tesla Model S key fob button side down on a soft cloth or surface. This will protect the buttons from scratches and provide a stable base to work on.
-
Open the Key Fob: Locate the bottom cover of the key fob. Use your small flat-bladed tool to gently release this cover. Insert the tool into the small slot on the side of the key fob and carefully pry it open. You should hear a click as the cover releases.
-
Remove the Old Battery: Once the bottom cover is released, you’ll see the battery. Carefully remove the old battery by gently lifting it away from the retaining clips that hold it in place.
-
Insert the New Battery: Take your new CR2330 battery. It’s important to insert it correctly. Place the new battery with the ‘+’ side facing upwards. Avoid touching the flat surfaces of the battery with your fingers as this can reduce battery life. If you do touch them, wipe the battery clean with a soft cloth before installing it.
-
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. Press the cover firmly until it snaps securely back into place. You should hear a click confirming it is properly closed.
-
Test the Key Fob: After replacing the battery and closing the key fob, test its functionality. Try unlocking and locking your Tesla Model S to ensure the new battery is working correctly and the key fob is operating as expected.
Important Warnings and Safety Precautions
While replacing the key fob battery is a simple task, it’s crucial to be aware of these safety warnings:
- Battery Ingestion Hazard: Key fob batteries are small and can be a choking hazard, especially for children. They also contain chemicals that can cause internal burns if swallowed. Keep both new and used batteries away from children.
- Seek Medical Attention Immediately: If you suspect a battery has been swallowed or placed inside any part of the body, seek immediate medical attention.
- Secure Battery Compartment: Always ensure the battery compartment is securely closed after replacement. If it doesn’t close properly, stop using the key fob and keep it away from children.
- Battery Disposal: Dispose of used batteries responsibly according to local regulations for electronic waste. Do not dispose of them in general household waste.
