Programming a key for your Model 3 is straightforward, but it requires following specific steps to ensure the key is properly synced with your vehicle. Below, we’ll cover everything you need to know.
What You’ll Need
Tesla Model 3 Key Fob: Ensure you have the key fob you want to program.

Step-by-Step Guide to Programming a Key Fob
Step 1: Enter Your Vehicle
Sit in the driver’s seat of your Tesla Model 3 and ensure the vehicle is powered on.
Step 2: Access the Controls Menu
On the touchscreen, tap the Car Icon (bottom-left corner) to open the main menu.
Select “Locks” from the list of options.
Step 3: Start the Key Programming Process
In the “Locks” menu, tap “Keys” or “Key Fobs” (depending on your software version).
Select “Add Key” or “Program Key Fob”.
Step 4: Authenticate with Your Key Card
The touchscreen will prompt you to place your Tesla key card on the center console (near the wireless phone charger) to authenticate.
Hold the key card in place until the vehicle recognizes it and confirms authentication.
Step 5: Program the New Key Fob
Once authenticated, the touchscreen will instruct you to place the new key fob on the center console.
Place the key fob on the designated area and wait for the vehicle to detect it.
A confirmation message will appear on the screen once the key fob is successfully programmed.
Step 6: Test the New Key Fob
Remove the key fob from the center console and test its functionality:
Lock and unlock the doors.
Open the trunk and frunk (if applicable).
Start the vehicle by pressing the brake pedal with the key fob inside the car.

Key Card as Backup: Always keep your Tesla key card as a backup in case the key fob fails or the battery dies.
Troubleshooting Tips
Key Fob Not Detected: If the vehicle doesn’t detect the key fob, ensure the fob’s battery is charged. Replace the battery if necessary.
Authentication Failed: If the key card authentication fails, ensure the card is placed correctly on the center console and try again.
Software Update: Ensure your Tesla Model 3 is running the latest software version. If not, perform an update before programming the key.
