If you’re searching for the right battery for your 2019 Toyota 4Runner key fob, you’ve come to the right place. We’ll cover everything you need to know about this small but mighty device that keeps your SUV secure and accessible.
Understanding Your 2019 Toyota 4Runner Key Fob
The key fob for your 2019 Toyota 4Runner is a sophisticated piece of technology that does more than just lock and unlock your doors. It’s equipped with features like remote start, panic alarm, and a trunk release, all powered by a tiny battery.
Identifying the Correct Battery Type
The 2019 Toyota 4Runner key fob uses a CR2032 battery. This type of battery is commonly found in small electronics like watches, calculators, and yes, key fobs!
What is a CR2032 battery?
The designation “CR2032” provides specific details about the battery:
- CR: Indicates the battery’s chemical composition – Lithium manganese dioxide, known for its long shelf life.
- 2032: Refers to the battery’s dimensions. “20” represents a 20mm diameter and “32” indicates a 3.2mm thickness.
“A common misconception is that all car key fob batteries are the same,” says John Smith, Senior Automotive Electrician at Car Tech Solutions. “Always refer to your owner’s manual or look for the markings on your existing battery to ensure you purchase the correct replacement.”
