This guide will walk you through everything you need to know about your 2020 Toyota Highlander key fob battery, from the correct size to step-by-step replacement instructions.

Identifying the Right 2020 Toyota Highlander Key Fob Battery

The 2020 Toyota Highlander uses a CR2032 battery for its key fob. This small, circular battery is widely available at most electronics stores, pharmacies, and even supermarkets.

What tools do I need to change my key fob battery?

Replacing your key fob battery is a quick and easy process. You’ll need a small flat-head screwdriver or a similar tool to pry open the key fob casing. Some key fobs have a designated notch or slot for easier opening.

Step-by-Step Guide to Replacing Your 2020 Toyota Highlander Key Fob Battery

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 emergency key.
Separate the key fob halves: Use the emergency key or a flat-head screwdriver to carefully pry open the key fob casing. Start at the notch or seam where the two halves join. Be gentle to avoid breaking the casing.
Identify and remove the old battery: Once open, you’ll see the CR2032 battery. Carefully remove it by gently prying it out with your screwdriver or fingernail. Note the orientation of the battery for correct replacement.
Install the new battery: Insert the new CR2032 battery into the compartment, ensuring it sits correctly and matches the orientation of the old battery. Press it down firmly until it’s secure.
Reassemble the key fob: Align the two halves of the key fob casing and press them together until they snap shut.
Test the key fob: Try locking and unlocking your Highlander to ensure the new battery is working correctly.
