Changing the key fob battery is a simple task that can save you time and money. Knowing how to change the battery in your key fob can prevent you from being locked out of your car and avoid costly trips to the dealership or an auto locksmith. This guide will walk you through the process for various key fob types, offering clear instructions and helpful tips.
Locating the Key Fob Battery Compartment
The first step in changing your key fob battery is finding the battery compartment. Key fobs vary significantly in design. Some have a small release button or switch, while others require a small screwdriver or even a coin to pry open. Your car’s owner’s manual is the best resource for specific instructions for your make and model. Generally, the battery compartment is located on the back or side of the key fob.
Identifying the Correct Battery Type
Once you’ve opened the battery compartment, identify the type of battery your key fob uses. Common types include CR2032, CR2025, and CR1632. The battery type is usually printed on the battery itself. Make a note of it before heading to the store to purchase a replacement. Using the wrong battery type can lead to improper function or even damage to your key fob.
