Is your Toyota Prius key fob acting up? Are you experiencing a decreased range, or is your Prius beeping at you after you turn it off? These are common signs that your key fob battery is getting weak and needs replacing. Don’t worry, this is a simple task you can easily do yourself in just a few minutes. This guide will walk you through the process of changing the key fob battery in 2004-2009 Toyota Prius models, saving you time and money. Replacing your Prius key fob battery promptly is crucial because, unlike traditional cars, there’s no mechanical key to start your Prius if the fob battery dies completely. Let’s get started and ensure you’re never stranded!

Before you begin, gather these simple tools and parts:
- Small Phillips head screwdriver: A #0 precision screwdriver is ideal.
- Small flat-head screwdriver or paperclip: For prying open the battery compartment.
- CR2032 Battery: This is the standard battery for most Toyota Prius key fobs. You can find these at most drugstores, grocery stores, and online retailers.
