Common Causes and Solutions for a Key Fob Not Detected

There are several reasons why your 2015 Nissan Altima might not be recognizing your key fob. Let’s break them down, starting with the easiest fixes.

Dead Key Fob Battery

This is the most common culprit. A weak or dead battery can prevent the key fob from transmitting the signal your car needs.

How to check: Try using your spare key fob. If the spare works, it’s a good indication the battery in your primary fob is the issue.
How to fix: Replace the battery. You can find replacement batteries at most auto parts stores or online. Check your owner’s manual for the correct battery type. https://keyfobx.com/replace-key-fob-battery-nissan/ provides step-by-step instructions.

Interference
