Gathering the Necessary Tools
Before we begin, make sure you have the required tools:
- Flathead screwdriver
- CR2016 battery
If you need the battery, you can find it on Amazon for a few dollars. Once you have these items, you’re ready to proceed.
Opening the Key Fob
First, locate the indentation where the key ring attaches to the key fob. This is where you’ll insert your flathead screwdriver. Ensure the Toyota symbol is facing up. This orientation is crucial for the next steps.
Inserting the Screwdriver
Insert the screwdriver into the indentation and twist it gently. The key fob will start to crack open. Lift the back cover off carefully, keeping the key fob oriented as described.
Removing the Buttons
Underneath the back cover, you’ll see a piece of rubber holding the buttons. Be cautious, as these buttons can fall out easily. Set the back cover down carefully, ensuring it remains in the same orientation.
Accessing the Battery Compartment
Now, focus on the main part of the key fob. You’ll see an arrow indicating how to open the battery compartment. While it suggests using a coin, your flathead screwdriver will work just as well.
Opening the Battery Compartment
Insert the flathead screwdriver between the black part of the plastic and the clear area. Twist the screwdriver to lift the black piece of plastic. You don’t need to remove the clear plastic cover entirely.
Removing the Old Battery
Look for a small opening on the side of the battery compartment. Insert the corner of the flathead screwdriver into the opening and pry out the old battery. The CR2016 battery should come out easily.
Installing the New Battery
Take the new CR2016 battery and ensure the positive side is facing up. You should see the plus sign and the battery information.
Inserting the New Battery
Insert the new battery by positioning it towards the metal component first. Then, click the top part into place. Ensure the battery is secure before proceeding.
Reassembling the Key Fob
Place the black piece of plastic back on top of the battery compartment. Carefully lift the key fob and set the back cover on top. Click the back cover into place, ensuring everything is secure.
