Decoding Your 2020 Ford Expedition Key Fob Battery
The key to a smoothly operating key fob often lies within a small, yet powerful battery. For your 2020 Ford Expedition, this power source is a CR2450 battery.

- Pry Open the Fob: Insert the emergency key or your tool into the notch and gently twist to pry the two halves of the key fob apart. Be careful not to apply excessive force, as you could damage the casing.
- Identify the Battery: Once open, you’ll see the CR2450 battery. Take note of the battery’s orientation (+ side up).
