The convenience of modern technology has made our lives easier in many ways, but sometimes it can also be frustrating when it fails to function as expected. One such instance is when your car’s remote key fob stops working due to a dead battery. A car fob, also known as a remote keyless entry (RKE) system, is a vital component of your vehicle’s security and convenience features. It allows you to unlock and start your car without having to physically insert a key into the ignition. However, like any other electronic device, a car fob battery can drain over time, causing it to lose power and stop functioning.
Changing the battery in your car fob is a relatively simple process that can be done at home with a few basic tools. In this article, we will guide you through the steps involved in replacing the battery in your car fob, including the types of batteries used, the tools required, and some tips to keep in mind.

Types of Batteries Used in Car Fobs
Car fobs typically use small, specialized batteries that are designed to provide a high level of power in a compact package. The most common types of batteries used in car fobs are:
- CR2032: This is the most widely used battery type in car fobs. It is a 3-volt lithium coin cell battery that is widely available at most electronics stores.
- CR2031: This is a slightly smaller version of the CR2032 battery, but it is still widely used in many car fobs.
- CR2450: This is a larger version of the CR2032 battery, but it is less common in car fobs.
It is important to note that not all car fobs use these battery types, so it is always a good idea to check your car’s owner’s manual or the manufacturer’s website to determine the correct battery type for your specific vehicle.
