Replacing the battery in your 2018 Audi key fob is a simple task that can save you time and money. This guide will provide you with step-by-step instructions and helpful tips to make the process smooth and effortless.
Understanding Your 2018 Audi Key Fob
Before we dive into the battery replacement process, it’s important to understand the different types of key fobs used in 2018 Audi models. Some models use a traditional key fob with a physical key blade, while others utilize a keyless entry system with a proximity key. Knowing your key fob type will help you identify the correct battery replacement procedure.
Identifying the Correct Battery
Most 2018 Audi key fobs use a CR2032 battery. This small, circular battery is readily available at most electronics stores, pharmacies, and online retailers. It’s always recommended to have a spare CR2032 battery on hand to avoid any unexpected lockouts.

Changing the battery in your 2018 Audi key fob is a straightforward process that typically requires only a few minutes and a small flathead screwdriver. Here’s a detailed guide:
