How to Change Your 2020 Toyota RAV4 Hybrid Key Fob Battery
1. Gather Your Tools and Supplies
The only tools you typically need for this process are a small flathead screwdriver or a similar tool to pry open the key fob, and a new CR2032 battery.

Always ensure you are working in a well-lit area.

Some models might require a twisting motion with the screwdriver after insertion to effectively separate the halves. You'll be looking for solutions for a stuck key fob .

Once the key fob is open, you'll see the old CR2032 battery. In many cases, it's held in place by a small plastic clip or retaining mechanism. Use your fingernail or the tip of the screwdriver to gently pry the battery loose. Pay attention to the orientation of the battery (positive side up or down) before removing it. Note down the battery direction to ensure correct replacement.
Avoid using metal tools to pry the battery directly, as this could short-circuit the battery or damage the fob's internal components.
5. Install the New Battery
Insert the new CR2032 battery into the battery compartment, ensuring that it's oriented correctly according to the previous battery's position. The positive (+) side of the battery should typically face up or down, depending on the design of the fob. Push the battery down until it clicks into place, securing it under the retaining clip (if applicable). Verify that the battery is firmly seated and makes good contact.

Carefully align the two halves of the key fob casing and press them together until they snap securely into place. Ensure that all the clips are properly engaged and that there are no gaps between the two halves. Insert the emergency key back into the fob until it clicks into the locked position. Ensure a tight seal to prevent moisture from entering the fob.
