That enigmatic circle arrow on your key fob. You’ve seen it, maybe even pressed it out of curiosity, but do you really know what it does? In an age where our cars are increasingly connected and feature-rich, understanding every button on your key fob is crucial. This seemingly simple symbol hides a valuable function, often related to remote starting or other advanced features. Let’s delve into the world of key fobs and unlock the mystery behind that circle arrow.
The Ubiquitous Circle Arrow: More Than Just a Button
The circle arrow, typically depicted with the arrow’s head meeting its tail, is a universally recognized symbol. However, its specific function on a key fob can vary depending on the car manufacturer, model, and year. While some may associate it exclusively with remote starting, this is not always the case.
