How to Take the Battery Out of a Toyota Key Fob

If your Toyota key fob has stopped unlocking or locking your car doors, the culprit is often a dead battery. Luckily, replacing the battery in most Toyota key fobs is a quick and easy DIY job. This guide will walk you through the simple steps of how to take the battery out of a Toyota key fob so you can get back on the road in no time.

Locating the Battery Compartment

Before you begin, you’ll need to gather a few things:

Your Toyota Key Fob: This might seem obvious, but it’s important to start with the right key fob.
A Small Flathead Screwdriver: This will be used to pry open the key fob casing.
A Replacement Battery: Toyota key fobs typically use a CR2032 battery, but double-check your owner’s manual to be sure.

Now, let’s locate the battery compartment:

Examine Your Key Fob: Most Toyota key fobs have a small seam or groove running along the edge. This usually indicates the location of the battery compartment cover.
Locate the Release Button/Switch: Some Toyota key fob models might have a small release button or switch on the back. If you find one, press it to detach the key fob cover.

Opening the Key Fob

Insert the Screwdriver: Carefully wedge the tip of your flathead screwdriver into the seam or groove of the battery compartment cover.
Gentle Pry: Apply gentle pressure and pry the cover open. Be careful not to use excessive force, as this could damage the key fob casing. The cover should pop open easily.

Removing and Replacing the Battery

Identify the Battery: Inside, you’ll find a small, round, silver battery. This is the CR2032 battery that powers your key fob.
Note the Orientation: Pay attention to which side of the battery is facing up – usually the positive (+) side is facing up.
Remove the Battery: Gently pry out the battery using your fingernail or the tip of your screwdriver.
Insert the New Battery: Place the new CR2032 battery into the compartment, ensuring it matches the same orientation as the old battery.
Reassemble the Key Fob: Align the cover and press it firmly back into place until you hear a click.

Testing the Key Fob

Once you’ve replaced the battery, test all the buttons on your key fob to ensure it’s functioning properly. If your Toyota still isn’t responding to the key fob, there may be another issue at play.
