How to Change the Battery on a Nissan Key Fob

Changing the battery in your Nissan key fob is a quick and easy process that can save you the hassle and expense of a trip to the dealership. This guide will walk you through the steps involved in replacing the battery for various Nissan key fob models.

Understanding Your Nissan Key Fob

Before we dive into the battery replacement process, it’s important to understand the different types of Nissan key fobs. Knowing your key fob type helps ensure you follow the correct procedure. There are generally two main types: the traditional flip key and the smart key/keyless entry remote. Each type has a slightly different battery replacement procedure. Understanding this distinction will make the process smoother and prevent any accidental damage to your key fob.

Identifying Your Key Fob Type

• Flip Key: This type of key has a physical key blade that folds into the fob. It usually has buttons for lock, unlock, and panic.
• Smart Key/Keyless Entry Remote: This type of key fob is typically thicker and doesn’t have a visible key blade. It allows for keyless entry and push-button start. Some models may have a hidden emergency key blade.

Gathering Your Tools and Supplies

Before you begin, gather the necessary tools and supplies. You’ll need:

1. A small flathead screwdriver or a similar tool for prying open the key fob.
2. A new CR2032 or CR2025 battery (check your owner’s manual for the correct type). Having the correct battery is crucial for proper key fob operation.
3. Optional: A small container to hold the screws and other small parts to prevent loss.
