- Battery: Provides power to the electronic circuitry.
- Transponder Chip: A small microchip embedded in the key blade that contains a unique identification code.
- Buttons: Used to lock, unlock, and trunk release functions.
- Antenna: Allows the key fob to communicate with the vehicle’s immobilizer system.
Identifying the Battery Type
The type of battery used in your Ford Explorer key fob will vary depending on the model year and trim level. Common battery types include CR2032, CR2025, and CR1616. It’s crucial to use the correct battery size and type to ensure proper functionality. You can usually find the battery type printed on the back of the key fob or in your vehicle’s owner’s manual.

Before you begin, gather the following tools and materials:

Carefully align the back cover of the key fob and snap it back into place. Ensure that the cover is securely closed.
