In this blog post, we’ll explain how to replace the battery in your Prius key fob, so you can continue to enjoy all the benefits that this car has to offer.

Replace The Prius Key Fob Battery-Step By Step Guide

If you own a Toyota Prius, chances are you’re familiar with the key fob.

The key fob is a small, hand-held remote that controls various functions on your car.

It can be used to lock and unlock the doors, open the trunk, and even start the engine.

Most key fobs use a CR2032 battery, which is a coin-shaped battery that’s about the size of a dime.

Over time, these batteries will begin to die and will need to be replaced.

When this happens, you’ll notice that your key fob starts to act erratically.

The doors may not unlock when you press the button, or the trunk may not open.

In some cases, you may even have trouble starting the engine.

If you’re having any of these problems, it’s likely that your key fob battery is dead and needs to be replaced.

Fortunately, replacing the battery in a Prius key fob is a relatively easy process that can be done in just a few minutes.

To replace the battery in your Prius key fob, you’ll need:

  • A new CR2032 battery
  • A small flathead screwdriver or a jeweler’s screwdriver set
  • A lint-free cloth (optional)

Once you have all of the necessary tools, follow these simple steps:

Step#1

Start by removing the key fob from your key ring.

Most key fobs have a small release button that you can press to detach the fob from the key ring.

If your key fob doesn’t have a release button, you’ll need to use a small flathead screwdriver to pry it off.

Step#2

Once the key fob is detached from the keyring, flip it over so that you can see the backside.

You should see a small Phillips head screw holding the back of the case in place.

Use a Phillips head screwdriver to remove these screws and set them aside in a safe place.

If your key fob has more than two screws, make sure to keep track of which screws go in which holes.

This will make it easier to put the key fob back together later.

Step#3

Once the screws have been removed, gently pull the back of the case away from the rest of the key fob.

If it’s stuck, you can use a small flathead screwdriver to pry it loose.

Be careful not to damage any of the components inside the key fob as you remove the back of the case.

Step#4

With the back of the case removed, you should now be able to see the battery inside.

The battery is held in place by a small metal retaining clip.

Use your fingers or a small pair of needle-nose pliers to remove this clip and set it aside.

Step#5

Once the retaining clip has been removed, you can now remove the old battery from the key fob.

To do this, simply pull on the battery until it pops out of its slot.

Be careful not to touch any of the exposed electronics with your fingers as you remove the battery.

Step#6

With the old battery removed, you can now install the new one.

Start by gently inserting the new battery into its slot, making sure that the positive side (the side with the + symbol) is facing up.

Once the new battery is in place, replace the metal retaining clip to hold it in place.

And that’s it!
