The key fob for your 2016 Nissan Sentra plays a crucial role in your daily commute. It allows for keyless entry and ignition, making your driving experience that much smoother. However, like all electronics, your key fob relies on a battery, and specifically a CR2032 lithium coin cell battery, to power these convenient features. Over time, this battery will eventually drain, requiring a replacement. Don’t panic when this happens! Changing the battery in your 2016 Nissan Sentra fob key is a simple process that you can do yourself at home with just a few tools and a few minutes of your time. This comprehensive guide will walk you through each step, ensuring you get back on the road with minimal hassle.
