Test the key to make sure that the new battery is working. You should be able to unlock or lock the doors with your car remote without any issues.

Remember to dispose of the old battery properly, and avoid touching the new battery with your bare hands to prevent damage or malfunction.

Step 1: Access the Key Fob

1.1 Locate the Key Fob

The Toyota Prius key fob is a small plastic device that is used to control the locking/unlocking of the car doors, as well as to start/stop the vehicle. Before you can replace the battery, you’ll need to find the key fob.

• The key fob is typically attached to a keychain or a lanyard, so start by looking for those accessories.
• If you can’t find the key fob, check your pockets, purse, or any other place where you might have put it.
• If you still can’t locate the key fob, check the car’s manual for tips on where it might be located.

1.2 Open the Key Fob

Now that you have located the key fob, the next step is to open it up so that you can access the battery compartment. Follow these steps:

1. Take the key fob in your hand and locate the small release button on the back.
2. Press the release button to remove the metal key from the fob.
3. Once the metal key is removed, you should be able to see the battery compartment on the back of the fob.

Step 2: Open the Key Fob

Step 2.1: Locate the Key Release Button

The Toyota Prius key fob has a small button that you need to press in order to release the key. This button is located on the back of the key fob. Look for a small, round button that is next to the Toyota logo.

Step 2.2: Press the Key Release Button

Once you have located the key release button, press it down firmly. As you press the button, pull the metal key out of the key fob. The key should come out easily without too much force.

Step 2.3: Open the Key Fob

With the metal key removed from the key fob, you can now open the key fob to access the battery compartment. Hold the key fob face-down in your hand, and use your other hand to slip your fingers into the gap between the two halves of the key fob. Gently pry apart the two halves of the key fob until they separate.

Note: Be careful not to damage the key fob or its components as you pry it open.

• If you have trouble separating the two halves, use a flat-head screwdriver to gently pry them apart.
• Be sure to keep the two halves of the key fob together so that you do not lose any of the small components inside.

Now that the key fob is open, you are ready to replace the battery.

Step 3: Remove the Old Battery and Insert the New One

1. Locate the battery compartment

Before removing the old battery, you need to find the battery compartment. In most Toyota Prius models, the battery compartment is located on the back of the key fob. Look for a small button or tab that you can press to release the battery tray.

2. Remove the old battery

When you have located the battery compartment, open it and take out the old battery carefully. Be sure to note which side of the battery is facing up so you know how to insert the new battery.

If you are having trouble opening the battery compartment or removing the old battery, consult the owner’s manual or seek assistance from a professional mechanic.

3. Insert the new battery

Once you have removed the old battery, take the new battery and insert it into the tray in the same position as the old battery. Be sure that the positive and negative sides of the battery match the markings inside the battery compartment.

Close the battery compartment and ensure that it is securely latched in place. Your Toyota Prius key fob should now be ready to use with the new battery installed.
