Replacing the battery in your 2018 Chevy Tahoe key fob is a quick and easy process that can save you time and money. This guide will walk you through each step, from identifying the right battery to testing the fob after the replacement.
Understanding Your 2018 Tahoe Key Fob
Before we dive into the replacement process, it’s helpful to understand a bit about your key fob. The 2018 Tahoe typically uses a “smart key” fob, which allows for keyless entry and push-button start. These fobs rely on a small battery to power their functions. Over time, this battery will naturally deplete, leading to decreased range or even a completely unresponsive key fob. Knowing how to replace this battery yourself can prevent being stranded with a dead fob. Do you know that sinking feeling when you click your fob and…nothing? Yeah, let’s avoid that.
What You’ll Need for a 2018 Tahoe Key Fob Battery Replacement
- A new CR2032 battery: This is the standard battery for most 2018 Tahoe key fobs. Make sure you grab a fresh one for optimal performance.
- A small flathead screwdriver or a key: This will be used to pry open the key fob casing. Some fobs even have a small slot specifically for this purpose.
- Optional: A small plastic pry tool. This can help prevent scratching your key fob during the opening process.
