A dead key fob battery can leave you stranded, so knowing how to replace it yourself is a valuable skill. This guide provides a step-by-step walkthrough for various Nissan key fob models, ensuring you’re back on the road in no time.

Understanding Your Nissan Key Fob

Before diving into the battery replacement process, it’s important to identify the type of key fob you have. Nissan has used several different designs over the years, each with slight variations in the battery replacement procedure. Knowing your key fob type will help you follow the correct instructions and avoid any unnecessary complications. Common Nissan key fob types include the traditional switchblade key, the smart key fob with push-button start, and the intelligent key with remote start.

Identifying Your Key Fob Type

Look closely at your key fob. Does it have a physical key that folds out? If so, it’s likely a switchblade key. Does it have a hidden key that can be removed? Then it’s probably a smart key or intelligent key. Knowing this distinction will guide you to the correct instructions below.
