A key fob battery is a small, coin-shaped battery that powers a car’s remote keyless entry system. It allows the fob to send signals to the vehicle, enabling functions like locking or unlocking doors, starting the engine remotely, or opening the trunk. Most key fobs use lithium coin cell batteries, such as CR2032 or CR2025. Over time, the battery can lose power, leading to reduced range or complete failure of the fob. Replacing the battery is usually quick and inexpensive, and it restores full functionality to the key fob. Regular replacement helps avoid unexpected issues with vehicle access or ignition.
