Key Fob Batteries

A fob battery is a small, coin-shaped battery that powers key fobs, which are remote control devices used for keyless entry in vehicles, garage doors, and security systems. Typically, these batteries are lithium-based and come in various sizes, with CR2032 and CR2025 being among the most common. A fob battery is designed to provide long-lasting power, ensuring that your key fob operates reliably for extended periods.
