Signs of a Dying Key Fob Battery

  • Reduced range: You might notice you need to be closer to your vehicle for the key fob to function.

  2. Locate the key slot: On the side of your key fob, you’ll find a small slot.
  3. Open the key fob: Insert the flathead screwdriver into the slot and gently pry open the key fob casing. Be careful not to damage the plastic.
  4. Remove the old battery: Carefully remove the old CR2025 battery.
  5. Install the new battery: Insert the new CR2025 battery, ensuring the positive (+) side faces upwards.

Troubleshooting: Key Fob Still Not Working?

Sometimes, even after replacing the battery, your key fob might not work. Here are a few things to check:
