Gather Your Tools
Before you begin, make sure you have the necessary tools:
- Flathead screwdriver
- New CR2016 battery
Opening the Key Fob
First, examine the keyring area of your key fob. You’ll notice a small slot in the plastic. This is where you’ll insert your flathead screwdriver.
To prevent the buttons from falling out, hold the key fob with the Toyota symbol facing up. Insert the flathead screwdriver into the slot and twist it gently. This action will separate the two halves of the key fob.
Removing the Internal Components
Once the key fob is open, you’ll see a small black box inside. Carefully lift this box out. Be cautious as the buttons underneath may fall out. Place the black box aside.
You’ll notice that the black box has instructions indicating to use a coin to open it. However, a flathead screwdriver works just as well. Insert the screwdriver into the small clear opening and twist it to open the box.
Replacing the Battery
With the black box open, you’ll see the CR2016 battery inside. Use the corner of your flathead screwdriver to lift and pry the battery out gently. It should come out with minimal effort.
When inserting the new battery, ensure the positive side faces up. Click it back into place securely.
Reassembling the Key Fob
Now, it’s time to put everything back together. Carefully place the black box back into its original position inside the key fob. Ensure it’s sitting securely.
Finally, click the two halves of the key fob back together. Your key fob should now be functioning with a brand new battery.
