1. Why Does My Toyota Remote Need a New Battery?
Key fobs, or keyless entry remotes, are essential for modern Toyota vehicles. They offer convenient access and security features. However, like any battery-powered device, the battery in your Toyota remote will eventually need replacement.
1.1. Understanding Key Fob Technology
Key fobs use radio frequency identification (RFID) technology to communicate with your Toyota. They send signals to lock, unlock, and even start your vehicle. According to a study by the National Highway Traffic Safety Administration (NHTSA), keyless entry systems have significantly reduced vehicle theft.

Recognizing the signs of a weak battery can prevent you from getting stranded. Here are common indicators:
