How to Replace Your 2008 Infiniti EX35 Key Fob Battery
Replacing the battery in your 2008 Infiniti EX35 key fob is a straightforward process that you can typically do yourself in a few minutes. Here’s a general guide:

Locate the Emergency Key: Your Infiniti key fob includes a physical emergency key. Find the release button or latch on your key fob – it’s usually a small button or slider. Press or slide it to release and remove the emergency key.

Identify the Battery: Carefully open the casing to reveal the CR2032 battery. Note the orientation of the battery (+ side up or down) before removing it.
-
Remove the Old Battery: You can usually pry out the old battery with your fingertip or a small tool.
-
Insert the New Battery: Place the new CR2032 battery into the compartment, ensuring it’s in the correct orientation (usually + side facing up).
-
Close the Key Fob Casing: Carefully snap the key fob casing back together until it’s securely closed.
-
Test the Key Fob: Test the lock, unlock, and panic buttons to ensure the new battery is working correctly.
Important Note: While changing the battery is usually simple, always refer to your Infiniti EX35 owner’s manual for specific instructions for your model year, as slight variations might exist.
