Recognizing When to Replace Your Key Fob Battery
Under normal usage, the battery in your Tesla Model S key fob is designed to last approximately one year. However, this can vary based on your usage habits and specific vehicle settings.

Ignoring this warning can lead to inconvenient situations where your key fob becomes unresponsive when you need it most.
What You’ll Need for the Replacement
Before you begin the tesla model s key fob battery replacement process, gather these simple tools and components:
- A new CR2330 battery: This is the specific type of battery required for the Tesla Model S key fob. You can purchase CR2330 batteries from most retailers that sell batteries, including drugstores, supermarkets, and online marketplaces.
- A small flat-bladed tool or a thin pry tool: This tool will be used to gently open the key fob casing. A small screwdriver or even a plastic trim removal tool will work perfectly.
- A soft cloth or surface: Having a soft surface to work on will prevent scratches on your key fob during the battery replacement.
Step-by-Step Guide to Tesla Model S Key Fob Battery Replacement
Now, let’s get to the actual tesla model s key fob battery replacement. Follow these detailed steps carefully:
Step 1: Accessing the Battery Compartment
- Place your Tesla Model S key fob button side down on a soft surface. This protects the buttons from being pressed accidentally and prevents scratches.
- Locate the bottom cover of the key fob.
- Using your small flat-bladed tool, gently insert the edge of the tool into the seam where the bottom cover meets the main body of the key fob.
- Carefully pry the bottom cover open. You should feel it release with a gentle click. Avoid using excessive force to prevent damage to the key fob casing.
Step 2: Removing the Old Battery
- Once the bottom cover is removed, you will see the battery and the retaining clips holding it in place.
- Carefully lift the old battery out of the compartment. You may need to gently maneuver it to disengage it from the retaining clips.
- Take note of the orientation of the battery – specifically, the position of the positive (+) side. The positive side should be facing upwards when you remove it.
Step 3: Installing the New Battery
- Take your new CR2330 battery and ensure it is clean. It’s advisable to wipe the battery with a clean, dry cloth before installation.
- Crucially, avoid touching the flat surfaces of the battery with your bare fingers. Oils and contaminants from your fingers can reduce the lifespan of the battery. Hold it by the edges.
- Insert the new battery into the compartment, ensuring the positive (+) side is facing upwards, matching the orientation of the old battery you removed.
- Press the battery gently into place until it is securely held by the retaining clips.
Step 4: Reassembling the Key Fob
- Take the bottom cover and carefully align the tabs on the cover with the corresponding slots on the key fob body.
- Holding the cover at a slight angle can help with alignment.
- Once aligned, press the cover firmly onto the key fob until it snaps securely into place. You should hear a click, indicating that it’s properly closed.
Step 5: Testing the Key Fob
- After reassembly, it’s essential to test if the tesla model s key fob battery replacement was successful.
- Test the key fob by attempting to unlock and lock your Tesla Model S.
- If the key fob functions correctly, you have successfully completed the battery replacement. If it doesn’t work, re-check the battery orientation and ensure the cover is fully snapped closed.
Battery Type and Availability
As mentioned earlier, the Tesla Model S key fob uses a CR2330 battery. This type of coin cell battery is widely available and can be purchased from numerous retailers. You can find them at:
- Drugstores and Pharmacies
- Supermarkets and Grocery Stores
- Electronics Stores
- Online Retailers (like Amazon, etc.)

Purchasing batteries in multi-packs can be a cost-effective way to have spares on hand for future tesla model s key fob battery replacements.
Important Safety Warning
Warning: Key fob batteries are hazardous if swallowed. They contain chemicals that can cause serious internal burns. Tesla key fobs utilize a coin cell battery. If a coin cell battery is ingested, it can cause severe internal damage within just two hours and can be fatal.
- Keep both new and used batteries out of reach of children.
- 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.
- If you suspect a battery has been swallowed or placed inside any part of the body, seek immediate medical attention.
By following these steps, you can confidently perform a tesla model s key fob battery replacement and ensure your key fob continues to work reliably. This simple maintenance task can save you time and prevent potential frustrations.
