2007 Volvo S40 Key Fob Battery: A Comprehensive Guide

If you own a 2007 Volvo S40, chances are you’ve encountered issues with your key fob battery. A dead key fob battery is a common problem, but luckily, it’s an easy fix. This comprehensive guide will walk you through everything you need to know about your 2007 Volvo S40 Key Fob Battery, from identifying the signs of a dying battery to replacing it yourself.

Signs Your 2007 Volvo S40 Key Fob Battery Needs Replacing

Before you start digging around for a new battery, it’s essential to make sure that a dying battery is actually the culprit. Here are a few telltale signs that your 2007 Volvo S40 key fob battery needs replacing:

  • Decreased Range: The most common sign is a decreased range for your key fob. If you find yourself having to stand closer to your car to lock or unlock it, or if the key fob doesn’t work at all unless it’s very close to the car, it’s likely time for a new battery.
  • Intermittent Functioning: Is your key fob working sporadically? One moment it works fine, and the next it takes multiple presses to get it to register? This is another sign of a failing battery.
  • Dashboard Warning Light: Some Volvo S40 models may display a warning light on the dashboard if the key fob battery is low.
