How to Change the Battery in a Toyota Key Fob

Changing the battery in your Toyota key fob is a quick and easy process that can save you time and money. In this guide, we’ll walk you through the steps involved in replacing the battery in most Toyota key fobs.

Locating Your Key Fob’s Battery Compartment

The first step in changing your key fob battery is locating the battery compartment. Most Toyota key fobs have a small release button or switch, often on the side or back. Sometimes, it’s hidden under a small cover. This release button allows you to separate the key fob’s two halves to access the battery. Check your owner’s manual if you can’t find it.

Using a Flathead Screwdriver or Similar Tool

Gently insert the screwdriver into the notch and apply slight pressure to pry open the key fob casing. Be careful not to damage the plastic. Remember, a gentle touch is key! https://keyfobx.com/how-to-change-battery-in-2019-toyota-corolla-key-fob/
