What Kind of Battery Does My Key Infiniti Fob Need?

Infiniti key fobs, like most car key fobs, rely on small batteries to power their functions, from locking and unlocking your doors to starting your engine. Knowing what kind of battery your Infiniti key fob needs is crucial for maintaining its functionality and avoiding frustrating situations where your fob suddenly stops working. This article will guide you through everything you need to know about Infiniti key fob batteries, including the specific types, how to replace them, and some helpful tips for extending their lifespan.

Identifying Your Infiniti Key Fob Battery

The most common battery type for Infiniti key fobs is the CR2032. This is a small, circular, lithium coin cell battery readily available at most electronics stores, pharmacies, and online retailers. However, some older Infiniti models may use different batteries, so it’s always best to double-check. You can do this by consulting your owner’s manual, looking for markings inside the key fob battery compartment, or searching online for information specific to your Infiniti’s year and model. Finding the correct battery from the start saves you time and potential incompatibility issues.

Replacing the battery in your Infiniti key fob is usually a simple process you can do yourself. Here’s a general guide, but remember to consult your owner’s manual for specific instructions for your model:

Locate the release button or slot: This is usually a small button or slot on the key fob’s side or back.
