Step-by-step on-board programming
The 2024 Tesla Model 3 utilizes a key card, phone key, and an optional key fob. Programming the key fob is a straightforward process done directly through the vehicle's touchscreen.
- Ensure your phone key is active and linked to your Tesla account. This is often required for performing key-related functions.
- Access the "Locks" menu: On your Tesla's touchscreen, navigate to
Controls>Locks. - Add a new key: Tap the
+button (orAdd Key) to initiate the pairing process. - Place the new key fob: The screen will instruct you to place the key fob on the center console's card reader. This is typically located behind the cup holders or near the charging pad.
- Confirm pairing: Once the vehicle detects the new key fob, follow the on-screen prompts to confirm its addition. You may be asked to scan an existing key card to finalize the process.
- Test the new key fob: After successful pairing, test the lock, unlock, and trunk functions of your new key fob to ensure it's working correctly.
Note: If you encounter any issues, ensure your vehicle's software is up to date and refer to your Tesla owner's manual for specific troubleshooting steps.
Battery replacement
The Tesla Model 3 key fob uses a single CR2032 coin cell battery.
- Locate the seam: There's a small seam along the edge of the key fob.
- Pry open the case: Carefully use a small, flat-head screwdriver or a plastic pry tool to gently separate the two halves of the key fob.
- Remove the old battery: Note the orientation of the battery (positive side up) and carefully remove it.
- Insert the new battery: Place the new CR2032 battery into the compartment with the positive (+) side facing up.
- Snap the case back together: Align the two halves of the key fob and press them firmly until they snap back into place.
Where to buy a replacement fob
- Tesla Service Center: The most reliable option for purchasing an OEM Tesla key fob. You'll receive a genuine part guaranteed to work with your Model 3. Prices are generally higher, ranging from $150 to $200 for the fob itself, plus any potential service charges if you opt for them to program it (though it's usually a DIY process).
- Online Retailers (e.g., Amazon, eBay): You might find third-party key fobs advertised as compatible. However, exercise extreme caution. Tesla
