how to resolve a key fob that won't work on my Tesla Outback (2015-2019)?

Solution

1. Preparation

• Gather necessary tools: small flathead screwdriver, multimeter, and replacement battery (CR2032).
• Ensure the vehicle is in a safe location and turned off.

2. Replace Key Fob Battery

1. Open the Key Fob

   • Use a small flathead screwdriver to gently pry open the key fob casing at the seam.
   • Take care not to damage the casing.

2. Remove Old Battery

   • Take note of the battery orientation (+ and - sides).
   • Carefully remove the old battery from its compartment.

3. Install New Battery

   • Insert the new battery (CR2032) in the same orientation as the old battery.
   • Ensure it fits snugly in the compartment.

4. Reassemble Key Fob

   • Align the key fob casing halves and press them together until they click securely.

3. Reprogram Key Fob (if needed)

1. Enter Programming Mode

   • Inside the vehicle, press the brake pedal and put the vehicle in "Accessory" mode.

2. Initiate Key Fob Programming

   • On the touchscreen, navigate to the settings menu and select "Key Fob."
   • Follow onscreen prompts to add a new key fob.

3. Test Key Fob Functionality

   • After programming, test all functions of the key fob: locking, unlocking, and starting the vehicle.
