How to Change Battery in Toyota Prius Key Fob

Changing the battery in your Toyota Prius key fob is a quick and easy process that can save you the hassle and expense of a trip to the dealership. This guide will walk you through the steps involved, ensuring you’re back on the road with a fully functioning key fob in no time.

If your Prius key fob starts acting up, a dead battery is often the culprit. Symptoms like reduced range, intermittent functionality, or the need to be unusually close to the car to lock or unlock it are all signs that your key fob battery might need replacing. Fortunately, you don’t need to be a car expert to handle this simple task. Let’s dive into how to change the battery in your Toyota Prius key fob.

Identifying Your Toyota Prius Key Fob

Before you begin, it’s important to identify the specific type of key fob you have. Different model years may have slight variations in design and battery requirements. Check your owner’s manual for the specifics of your Prius. For example, changing the battery in a 2010 Toyota Prius key fob battery change is slightly different than a 2011 Toyota Prius 3 button key fob.

Gathering the Necessary Tools

You’ll need only a few simple tools:

• A small flat-head screwdriver or similar tool for prying open the key fob.
• A new CR2032 battery (this is the most common type for Toyota Prius key fobs, but double-check your owner’s manual).

Step-by-Step Guide: How to Change the Battery in Your Toyota Prius Key Fob

1. Locate the release button: On the side of your key fob, you’ll find a small release button. Press this button to release the metal key.
2. Use the metal key: Insert the metal key (or a small flat-head screwdriver) into the slot where the key was released. Gently pry open the key fob casing. Be careful not to damage the plastic.
3. Locate the old battery: Inside the key fob, you’ll see the CR2032 battery. Note its position and orientation.
4. Remove the old battery: Carefully pry the old battery out using your flat-head screwdriver or fingernail. Avoid puncturing the battery.
5. Insert the new battery: Place the new CR2032 battery into the compartment, ensuring it’s in the same orientation as the old battery. You should hear a small click when it’s properly seated.
6. Reassemble the key fob: Snap the two halves of the key fob casing back together. Make sure they fit snugly.
7. Test the key fob: Try locking and unlocking your car to ensure the new battery is working correctly.
