In this guide, I will show you how to replace a battery in a Jeep key fob with detailed instructions and helpful tips to make the process as easy and straightforward as possible. Whether you’re a seasoned jeep owner or a first-time key fob user, this guide will provide you with the information you need to keep your key fob in top working condition. 

Step 1: Gather the necessary tools and new battery.  

Getting the tools together is the first step in changing the battery in your Jeep key fob. All you will need is:

Garage Tools
  • A small flathead screwdriver 
  • A dry cloth 
  • A replacement battery (CR2032). This battery is commonly used in Jeep key fobs and can be purchased at most electronics stores, hardware stores, or online. Make sure you have these tools and the new battery ready before you begin the process.

Step 2: Locate the battery compartment 

You will find a small seam on the back of your key fob, which is made of plastic. This is where the battery compartment is located. Use the flathead screwdriver to smoothly open the battery compartment. Be careful that you don’t apply too much pressure when you try to open it, as this could damage the key fob case.

Step 3: Take out the old battery 

Once the compartment is open, you will see the old battery. Carefully remove the battery by gently pushing it out with your thumb or a pointy tool. Dispose of the old battery properly for recycling, as it can be harmful for nature if you throw it in your household waste. 

Step 4: Clean the key fob

Use a dry cloth to clean your key fob, removing any dust or debris that may have accumulated during its use or when you opened your key fob. This will help to ensure that your key fob continues to work properly in the future. You can also use a small brush or compressed air to remove any dust from the small gaps and buttons of your key fob if necessary.

Step 5: Insert the new battery 

Take your replacement battery and insert it into the compartment with the correct side facing up. Be sure to line up the positive and negative sides correctly. The positive side is marked with a plus sign and the negative side with a minus sign.

Step 6: Close the battery compartment 

Carefully press the battery compartment back into place; as it’s made of plastic, it can become fragile as it gets older. Make sure it snaps and is securely closed. Ensure that the compartment is closed tightly and that there are no gaps by pushing all around the key fob. This will prevent any moisture or dust from entering the key fob when using it, which could damage it.

Step 7: Test the key fob

Try the buttons on your key fob or get close to your Jeep to ensure that it’s working correctly. If it doesn’t work, double-check that the battery was inserted the right way and that the compartment is correctly closed. Try again to lock or unlock your car, and if the key fob still doesn’t work, you should probably bring it to a repair shop or dealership to check it.

Testing the key fob


  • Keep a spare battery on hand so you can change it as soon as the old one runs low.
  • Try replacing the battery yourself before taking it to a professional.
  • Dispose of the old battery properly according to your local regulations concerning recycling. It could be dangerous and harmful to nature if not disposed of correctly.
  • If you find yourself struggling with the process, take your key fob to a professional to have the battery changed.

4. Inconsistencies
