Replacing the key fob battery in your 2016 Toyota 4Runner is a simple task that can save you time and money. A dead key fob battery can leave you stranded, so knowing how to replace it is essential. This guide provides a step-by-step process, troubleshooting tips, and answers to frequently asked questions.
Recognizing a Dying Key Fob Battery
Several signs indicate your 2016 Toyota 4Runner key fob battery needs replacing. Reduced operating range is a common symptom. You might find yourself standing closer to your vehicle than usual to lock or unlock it. Another indicator is a weaker signal. The lock/unlock response might be sluggish or require multiple button presses. Sometimes, the key fob might not work at all.
Tools and Materials You’ll Need
The battery replacement process requires minimal tools. You’ll need a small flat-head screwdriver or a similar tool to pry open the key fob casing. Of course, you’ll also need a new CR2032 battery. These are readily available at most electronics and auto parts stores. Having a spare battery on hand is always a good idea.
