Step-by-Step Instructions
Step 1: Locate the Indentation
First, hold your key fob with the back side facing up. This means the buttons should be facing down and the Toyota symbol should be facing up. Look for the key ring attachment point. On the side, you will see a small slot or indentation along the seam of the plastic.
Step 2: Open the Key Fob
Take your flathead screwdriver and insert it into the indentation you located in Step 1. Twist the screwdriver gently. This action will cause the back part of the key fob to click off. Hold the key fob carefully to prevent the buttons from falling out.
Step 3: Remove the Internal Components
Once the back part of the key fob is off, carefully lift out the internal components. Be cautious as the small buttons inside may fall out if you are not careful. Set the back part of the key fob aside.
Step 4: Open the Battery Compartment
Now, look at the top of the key fob. There is a small space between the black plastic and the clear plastic. Use the same flathead screwdriver, or a coin if you prefer, and insert it into this space. Twist gently to open the battery compartment.
Step 5: Remove the Old Battery
With the battery compartment open, use the corner of the flathead screwdriver to lift out the old battery. Be gentle as there are delicate parts inside the key fob. The battery should come out easily with a little twist or push.
Step 6: Insert the New Battery
Take your new CR2016 battery and ensure the positive side is facing up. Slide the battery into the compartment and click it down into place. Sometimes the little rubber part inside may get in the way; you can adjust it with your flathead screwdriver.
Step 7: Reassemble the Key Fob
Now that the new battery is in place, it’s time to reassemble the key fob. Start by putting the black part back on and clicking it together carefully. Lift up your key and set the internal components with the clear plastic and buttons facing down. Click the back part of the key fob back into place.
