Tools and Materials Needed

Step-by-Step Guide

Step 1: Locate the Notch

First, identify the notch on the key fob. This notch is located on the upper right side of the fob, where your index finger would naturally rest. It’s a small indentation that allows you to separate the two halves of the fob.

Step 2: Insert the Screwdriver

Next, insert a small flat-head screwdriver or even another key into the notch. Apply a little pressure and twist gently. This will start to separate the two pieces of the key fob.

Step 3: Separate the Two Halves

Continue twisting until the two halves of the fob start to separate. Once you see a gap forming, you can use your fingers to pull the two pieces apart completely.

Step 4: Remove the Old Battery

With the fob open, you’ll see the old CR2032 coin battery. Carefully tap it out of its holder. Make sure to note the orientation of the battery before removing it. The positive side should be facing up.

Step 5: Insert the New Battery

Take your new CR2032 coin battery and place it into the holder with the positive side facing up. Ensure it sits snugly in place. Double-check that the rubber piece covering the battery is also in its correct position.

Step 6: Reassemble the Key Fob

Once the new battery is securely in place, align the two halves of the key fob and press them together until they snap back into place. Your key fob should now be fully functional.

Why Use a CR2032 Battery?

The CR2032 coin battery is a three-volt lithium battery commonly used in small electronics. It provides a reliable power source for the key fob, ensuring long-lasting performance. Always use a high-quality battery to avoid frequent replacements.
