Just like any battery-powered device, the battery in your Toyota key fob will eventually need replacing. A dead or dying key fob battery can be a real inconvenience, leaving you unable to remotely lock or unlock your doors, or even start your vehicle in some cases. Fortunately, replacing the battery in most Toyota key fobs is a straightforward process you can easily do yourself at home. This guide from the experts at keyfobx.com will walk you through each step, ensuring you can quickly get your key fob working like new again.
Step-by-Step Toyota Key Fob Battery Replacement
Changing your Toyota key fob battery is a simple DIY task. Follow these steps to get the job done quickly and efficiently:
-
Locate and Remove the Mechanical Key. Almost all Toyota key fobs come with a physical key hidden inside. Look for a small release button, usually a metal or plastic tab, on your key fob. Press and hold this button while gently pulling out the mechanical key. This key can be used to manually unlock your car door if your key fob battery is completely dead, and is also necessary to open the key fob casing.
-
Open the Key Fob Casing. With the mechanical key removed, you’ll see a slot or seam where the key was located. This is where you need to open the key fob. Use a small flathead screwdriver or a thin, sturdy object like a guitar pick or even the mechanical key itself. Carefully insert the flat tool into the slot and gently twist or pry to separate the two halves of the key fob casing. Take your time and avoid applying excessive force to prevent damaging the plastic.
-
Access and Remove the Old Battery. Once the key fob is open, you’ll see the internal components, including the battery. The battery is usually a small, round, silver disc. Note the type and orientation of the battery before removing it. Most Toyota key fobs use a CR2032 3V lithium battery. You can usually find the battery type printed on the battery itself. Carefully remove the old battery. You might be able to gently pry it out with your fingertip, or you can use the tip of a small screwdriver if needed, being careful not to scratch the circuit board.
-
Install the New Battery. Take your new CR2032 battery and install it in the same orientation as the old one. Usually, the positive (+) side of the battery faces upwards, but double-check the markings in the battery compartment to be sure. Push the new battery firmly into place to ensure good contact.
-
Reassemble the Key Fob. Carefully align the two halves of the key fob casing and press them back together until they snap securely into place. Ensure there are no gaps and the casing is fully closed. Finally, slide the mechanical key back into the key fob until it clicks and locks into position.
When Do You Need a Full Toyota Key Fob Replacement?
While battery replacement solves most key fob issues, sometimes a full Toyota key fob replacement is necessary. This is typically the case if your key fob is lost, stolen, or severely damaged. If your key fob is physically broken, water damaged, or if replacing the battery doesn’t solve the problem, it’s likely time for a replacement.
Getting a new Toyota key fob usually involves visiting a Toyota dealership or a qualified locksmith. They will be able to provide you with a new key fob and program it to work with your vehicle’s security system. While replacing the battery is a simple DIY task, key fob programming and replacement often require specialized equipment and expertise.
