Step-by-Step Battery Replacement
Step 1: Locate the Indentation
First, find the small indentation on the side of the key fob where the key ring attaches. This is where you’ll insert the flathead screwdriver.
Step 2: Open the Key Fob
Make sure the Toyota symbol on the back of the key fob is facing up. Insert the screwdriver into the indentation and twist gently. This will open the key fob.
Be careful to keep the key fob oriented this way to prevent the buttons from falling out.
Step 3: Remove the Buttons
Once the key fob is open, you will see the buttons. Carefully lift them out and set them aside. This will make it easier to access the battery compartment.
Step 4: Open the Battery Compartment
Look for a small space between the black plastic and the clear plastic at the bottom of the key fob. Insert the flathead screwdriver or a coin into this space and twist to open the battery compartment.
Step 5: Remove the Old Battery
Now, you can see the battery. Use the corner of the flathead screwdriver to gently wiggle the old battery out. Be careful not to damage the plastic around it.
Step 6: Insert the New Battery
Take your new CR2016 battery and make sure the positive side (marked with a +) is facing up. Click it into place in the battery compartment.
Step 7: Reassemble the Key Fob
Reinsert the buttons into their slots. Carefully place the battery compartment back into the key fob. Make sure everything is aligned properly before clicking the key fob shut.
