What You’ll Need for a Key Fob Battery Replacement
Replacing your 2018 Jeep Wrangler key fob battery requires minimal tools and a few minutes of your time. Here’s what you’ll need:
- A new CR2032 battery: This is the standard battery type for most Jeep Wrangler key fobs. You can find these batteries at most drugstores, grocery stores, and online retailers.

Step-by-Step Guide to Replacing Your Key Fob Battery
Follow these simple steps to replace the battery in your 2018 Jeep Wrangler key fob:
- Locate the Notch: On the back of your key fob, you’ll find a small notch or indentation. This is where you’ll insert your flathead screwdriver or pry tool.
- Open the Key Fob Case: Carefully insert the flathead screwdriver or pry tool into the notch and gently twist. This should separate the two halves of the key fob case. You may hear a slight click as it opens.
- Remove the Old Battery: Once the case is open, you’ll see the battery. Note the orientation of the battery (positive side up or down) before removing it. You can usually pry the old battery out with your fingertip or the flathead screwdriver if needed.
- Insert the New Battery: Place the new CR2032 battery into the battery compartment, ensuring it’s in the correct orientation (matching how the old battery was placed).
- Close the Key Fob Case: Carefully align the two halves of the key fob case and press them firmly together until they snap back into place. Ensure the case is fully closed and secure.
- Test Your Key Fob: Try using your key fob to lock and unlock your Jeep Wrangler to confirm the new battery is working correctly.
