What is a Car Fob Battery?
A car fob battery is a small, specialized battery designed to power the remote keyless entry system in your vehicle. These batteries are typically CR2032 or CR2450 in size and are used to provide power to the fob’s electronic components. The battery is responsible for transmitting the signal to the vehicle’s computer, which then unlocks or starts the engine.
Why Do Car Fob Batteries Drain So Quickly?
Car fob batteries are notorious for draining quickly, often leaving you stranded with a dead fob. There are several reasons for this:
- Constant use: Car fobs are designed to be used frequently, which means the battery is constantly being drained.
- Interference: Other electronic devices in your vehicle can interfere with the fob’s signal, causing the battery to drain faster.
- Weak battery: Over time, the battery’s capacity to hold a charge can decrease, leading to faster drainage.

There are several types of car fob batteries available, each with its own unique characteristics:
