How to Replace Your 2018 Jeep Key Fob Battery

Replacing your 2018 Jeep key fob battery is usually straightforward. Here’s a general guide, but remember to consult your owner’s manual for model-specific instructions.

3. Open the Key Fob: Use the flathead screwdriver to carefully pry open the key fob casing along the seam where the two halves meet. Be gentle to avoid damaging the plastic.

4. Remove the Old Battery: Once the fob is open, you should see the CR2032 battery. Use your screwdriver to gently pry the battery out of its slot.

5. Install the New Battery: Insert the new CR2032 battery into the slot, making sure the positive (+) side is facing upwards.

• Intermittent Functionality: This could indicate a loose connection within the key fob. Try opening the fob again and ensuring all components are securely in place.
