As a proud Toyota owner, you understand the importance of having a reliable and functional key fob. However, when the battery in your key fob starts to drain, it can be frustrating and inconvenient. One of the most common questions Toyota owners ask is, “What kind of battery does my Toyota key fob take?” In this article, we will delve into the world of key fob batteries, exploring the different types of batteries used in Toyota key fobs, how to replace them, and provide valuable tips on how to extend the life of your key fob battery.
Understanding Toyota Key Fob Batteries
Toyota key fobs are equipped with small batteries that power the device, allowing you to lock, unlock, and start your vehicle remotely. The type of battery used in your Toyota key fob depends on the model and year of your vehicle. The most common types of batteries used in Toyota key fobs are CR1632, CR2032, and CR2450. These batteries are small, round, and typically have a diameter of 16mm, 20mm, or 24mm, respectively.
Types of Toyota Key Fob Batteries
The CR1632, CR2032, and CR2450 batteries are all lithium coin cell batteries, which are known for their high energy density, long shelf life, and reliability. CR1632 batteries are commonly used in older Toyota models, while CR2032 batteries are used in most modern Toyota vehicles. CR2450 batteries are less common but may be used in some specialty or high-end Toyota models.
Battery Characteristics
When selecting a replacement battery for your Toyota key fob, it’s essential to consider the battery’s characteristics, such as its voltage, capacity, and chemistry. The voltage of a CR1632, CR2032, or CR2450 battery is typically 3 volts, which is sufficient to power the key fob’s electronics. The capacity of the battery, measured in milliampere-hours (mAh), determines how long the battery will last. A higher capacity battery will generally last longer than a lower capacity battery.

What is the typical lifespan of a Toyota key fob battery?
The typical lifespan of a Toyota key fob battery is around 2-3 years, but it can vary greatly depending on several factors. These factors include how often you use your key fob, the climate you live in, and the type of battery used. If you live in an area with extreme temperatures, your key fob battery may not last as long as someone who lives in a more moderate climate. Additionally, if you use your key fob frequently, the battery will drain faster than someone who only uses it occasionally.
To maximize the lifespan of your Toyota key fob battery, it’s essential to take proper care of it.
