Required Tools and Materials

Before you begin, make sure you have the necessary tools and materials. You will need:

  • CR2025 coin battery
  • Your Toyota Yaris iA key fob

If you don’t have a CR2025 battery, you can get one from Amazon.

Step 1: Removing the Internal Key

The first step is to remove the internal key from the fob. Flip the key fob over to the back. You will see a small switch.

Hold down the switch while pulling out the internal key. This key will be used to open the fob.

Step 2: Opening the Key Fob

Now that you have the internal key, insert it halfway into the slot on the side of the key fob.

Hold the front half of the device and twist the key. You will hear a cracking sound, which indicates the fob is opening.

Don’t worry; this sound is normal and means the fob is coming apart as it should.

Step 3: Accessing the Battery

Once the key fob is open, you will see a small plastic disc sitting on top of the battery.

Lift this disc out and set it aside. You will now see the CR2025 battery.

Step 4: Replacing the Battery

Remove the old CR2025 battery and dispose of it properly. Take your new CR2025 battery and make sure the positive side is facing up.

Slide the new battery into the slot where the old battery was.

Step 5: Reassembling the Key Fob

Place the plastic disc back on top of the new battery. Press it down so it sits flush with the surrounding plastic.

Make sure the battery is secure and making contact.

Click the two halves of the key fob back together. Insert the internal key back into its slot.
