How to Change the Battery in a Toyota Prius Key Fob: A Step-by-Step Guide

Once you have your tools and new battery, follow these simple steps:

Locate the release button. On the back of your key fob, you’ll see a small button or sliding tab. This is the release button for the mechanical key.
Release the mechanical key. Press the release button and gently slide the mechanical key out of the key fob.
Open the key fob. Use the tip of the flat-head screwdriver to carefully pry open the key fob casing. There is usually a small notch where the two halves of the key fob connect. Insert the screwdriver into the notch and gently twist to separate the halves.
Remove the old battery. Once the key fob is open, you’ll see the old battery. It is usually held in place by a small clip. Gently lift the clip and remove the old battery.
Install the new battery. Insert the new CR2032 battery into the battery compartment, making sure the positive (+) side is facing up.
Reassemble the key fob. Align the two halves of the key fob and press them together until you hear a click.
