What Is a Prius Key Fob and Why Do You Need to Replace Its Battery?
A Prius key fob is a remote device used to unlock and start a Toyota Prius vehicle. It operates through radio frequency signals that communicate with the car’s ignition system and security features.
According to Toyota, the key fob enhances convenience and security, allowing drivers to access their vehicles without inserting a traditional key.
The key fob contains a battery that powers its functions, including remote locking, unlocking, and engine start capabilities. When the battery is low or dead, the key fob may become unresponsive, making it impossible to access the vehicle.
