Solution

If your Tesla Model Y's key fob is not working, follow these detailed steps to diagnose and resolve the issue.

Repair Instructions

Step 1: Replace Key Fob Battery

Open the Key Fob:
- Use the flathead screwdriver or coin to gently pry open the key fob at the seam.
- Be careful not to damage the casing.
Remove the Old Battery:
- Take note of the battery orientation before removing.
- Replace with a new CR2032 battery, ensuring the positive (+) side is facing up.
Reassemble the Key Fob:
- Align the two halves of the fob and press them together until they snap back into place.

Step 2: Re-pair the Key Fob

Enter the Vehicle:
- Sit in the driver’s seat with the functioning key fob.
Access the Touchscreen:
- Tap on 'Controls' > 'Locks' on the vehicle's touchscreen.
Add Key Fob:
- Select the option to add a key fob.
- Follow the on-screen prompts to place the key fob near the center console (where the key fob reader is located).
- Wait for confirmation that the key fob has been successfully paired.

Step 3: Check for Software Updates

Access Software Settings:
- On the touchscreen, go to 'Controls' > 'Software'.
Update Software:
- If there is an available update, follow the prompts to install it.
- Ensure the vehicle is connected to Wi-Fi for the update process.

Step 4: Inspect for External Interferences

Check for Interference:
- Move away from other electronic devices or sources of radio frequency interference.
- Test the key fob again from different locations.

Step 5: Factory Reset (Last Resort)

Backup Data:
- Ensure any important data/settings are backed up as a factory reset may erase personal settings.
Perform Factory Reset:
- Go to 'Controls' > 'Service' > 'Factory Reset'.
- Confirm the reset and allow the vehicle to reboot.

Conclusion

After performing these steps, your key fob should be functioning properly. If the key fob continues to experience issues despite these troubleshooting methods, consider reaching out to Tesla customer support or visiting a Tesla service center for further diagnosis and potential replacement of the key fob.
