What type of battery is used in a Toyota 4Runner key fob?
The battery used in a Toyota 4Runner key fob is a small, coin-shaped lithium battery. This type of battery is commonly used in small electronic devices, such as key fobs, remote controls, and watches. The lithium battery provides a long-lasting and reliable source of power for the key fob’s electronic components, including the transmitter and receiver. It is designed to be compact and lightweight, making it ideal for use in small devices like key fobs.
The specific type of lithium battery used in a Toyota 4Runner key fob is typically a CR2032 or a CR1632, depending on the model year and type of key fob. These batteries are widely available at most hardware stores, auto parts stores, and online retailers. They are also relatively inexpensive, with a typical cost ranging from $2 to $5 per battery. It is recommended to replace the battery with a new one of the same type and size to ensure proper functionality and to avoid any potential compatibility issues.
How do I determine the correct battery size for my Toyota 4Runner key fob?
To determine the correct battery size for your Toyota 4Runner key fob, you can consult the owner’s manual or the manufacturer’s website.

These batteries are designed to provide a long-lasting and reliable source of power, and they are widely available at most hardware stores and auto parts stores.

You may also notice that the key fob’s buttons require more pressure to operate or that the lights on the key fob are dimmer than usual. If you notice any of these symptoms, it is likely time to replace the battery.
To replace the battery, you will need to purchase a new CR2032 or CR1632 lithium battery, depending on the type of key fob you have. You can find replacement batteries at most hardware stores, auto parts stores, or online retailers. Once you have the new battery, simply remove the old one from the key fob and replace it with the new one. Make sure to handle the battery carefully and avoid touching the electrical contacts to prevent damage or corrosion.
Can I replace the battery in my Toyota 4Runner key fob myself?

To replace the battery, simply remove the screw or clip that holds the case together, carefully pry the case open, and remove the old battery. Then, insert the new battery and reassemble the case.
It is recommended to consult the owner’s manual or a repair manual for specific instructions on replacing the battery in your Toyota 4Runner key fob. You can also find videos and tutorials online that can provide step-by-step guidance. If you are not comfortable replacing the battery yourself, you can take your key fob to a Toyota dealership or an auto parts store for assistance. The staff at these locations can replace the battery for you and ensure that the key fob is functioning properly.
How much does it cost to replace the battery in a Toyota 4Runner key fob?
