Toyota Highlander Key Fob Battery Replacement: A Step-by-Step Guide

In this article, you will learn how to replace the internal battery of your Toyota Highlander key fob. It’s a simple process that you can do at home with just a few tools.

To complete this task, you will only need a CR2032 battery, which is readily available and inexpensive. You can easily purchase one online through various retailers.

To start, locate the push button on the side of the key fob. Hold it down and pull out the internal key. You will notice a vertical and horizontal line on the key fob – you’ll need to use these as reference points to open the device.

Using a flathead screwdriver, carefully insert it into the designated area and gently twist to pry open the key fob. Once opened, you can remove the circuit board and access the old battery.

To remove the old battery, place the screwdriver between the battery and the plastic, apply gentle pressure, and wiggle it out. The CR2032 battery should easily pop out. Insert the new battery with the positive side facing up and reassemble the key fob.

Place the new battery on the circuit board, ensuring it makes contact with the designated circle. Once in place, reattach the back piece of the key fob and insert the internal key. Your key fob should now be good to go.
