This guide will equip you with everything you need to know about Prius key fob batteries, from identifying the correct type to choosing the best replacement option.
Why is My Prius Key Fob Battery Dying?
Before we dive into the specifics of battery types, let’s look at some common reasons why your Prius key fob battery might be draining too quickly:
- Age: Like all batteries, key fob batteries have a limited lifespan. Over time, their ability to hold a charge diminishes.

- Extreme Temperatures: Exposure to extreme heat or cold can shorten battery life.
