Replace Battery in Highlander Key Fob: A Comprehensive Guide

Replacing the battery in your Toyota Highlander key fob is a simple task you can do yourself, saving you a trip to the dealership. This guide will walk you through the process, highlighting common issues and providing expert tips to make the replacement smooth and efficient.

Understanding Your Highlander Key Fob

Before we dive into the replacement process, it’s helpful to understand the different types of Highlander key fobs. Older models might have a traditional key with a separate fob, while newer Highlanders often feature a smart key or push-to-start system with a more integrated key fob. Knowing your key fob type is crucial for selecting the correct battery. The most common battery type for Highlander key fobs is the CR2032, a small, circular, lithium battery readily available at most stores. However, always check your owner’s manual to confirm the specific battery type for your model year.

Gathering Your Tools and Materials

Replacing your Highlander key fob battery requires minimal tools. You’ll need:

• A new CR2032 battery (or the correct battery for your model)
• A small flathead screwdriver or a similar tool for prying open the key fob
• Optional: A small plastic pry tool to minimize the risk of scratching your key fob

Step-by-Step Guide to Replacing the Battery

Follow these steps to replace the battery in your Toyota Highlander key fob:

1. Locate the release button or slot: Examine your key fob carefully. There’s usually a small button or slot that releases the key from the fob or allows you to access the battery compartment.

2. Release the key (if applicable): If your key fob has a detachable key, release it using the release button. This will often expose the battery compartment.

3. Open the key fob: Using your flathead screwdriver or pry tool, carefully insert it into the designated slot or seam and gently pry open the key fob. Be careful not to apply excessive force, which could damage the casing.

4. Remove the old battery: Once the key fob is open, identify the old battery. Gently pry it out using your screwdriver or pry tool. Note the orientation of the battery for correct placement of the new one.

5. Insert the new battery: Place the new CR2032 battery into the compartment, ensuring it’s oriented correctly, matching the position of the old battery. Press it firmly into place.

6. Close the key fob: Align the two halves of the key fob and press them together until they snap shut.

7. Test the key fob: Check if the key fob functions correctly by locking and unlocking your Highlander.
