Step-by-step on-board programming
The 2025 Tesla Model 3 does not utilize a traditional key fob with on-board programming. Instead, Tesla vehicles primarily use a key card and the Tesla mobile app (phone-as-key) for locking, unlocking, and driving. Pairing these methods is done directly through the vehicle's touchscreen.
To pair a new key card or phone-as-key:
- Open the Tesla app on your paired phone or have your existing key card ready.
- On the Model 3 touchscreen, tap
Controls>Locks>Keys. - Tap the
+icon to add a new key. - Place the new key card on the card reader located behind the cup holders or follow the on-screen prompts for pairing your phone as a key via Bluetooth.
- Confirm pairing on the touchscreen. The vehicle will prompt you to authenticate with an existing key card or your phone-as-key that is already paired and authorized.
Important Considerations
- Phone as a Key: This is the primary method of access for most Tesla owners. Ensure Bluetooth is enabled on your phone and the Tesla app is running in the background. The app allows you to lock/unlock, start the car, and even summon it.
- Key Card: The key card serves as a backup and can be used to unlock the car by tapping it on the B-pillar sensor and to start the car by placing it on the center console reader. Guests can also use it.
Battery replacement
Since the Tesla Model 3 does not use a traditional key fob, there is no battery to replace in the conventional sense. The key card is a passive RFID device and does not contain a battery. Your phone, of course, has its own battery that needs to be charged regularly to use the phone-as-key feature.
Where to buy a replacement fob
As previously mentioned, the 2025 Tesla Model 3 does not use traditional key fobs. Your "replacement" options would involve obtaining a new key card or ensuring your phone is properly set up as a key.
- Tesla Service Center: This is the most reliable place to purchase a new key card. They can ensure the card is legitimate and properly paired with your vehicle. The cost for a new key card is typically around $35, though pricing can vary.
- Third-Party Vendors (e.g., Amazon, locksmiths): Be extremely cautious. While you might find "Tesla key cards" online, there
