Physical keys used to be the only way to start a car, but now key fobs have replaced them in many newer vehicles. A key fob is a small, electronic device that allows drivers to lock, unlock, and start their cars without ever having to insert a physical key. To start the car, the driver simply presses a button on the key fob, and the car’s engine turns on. This technology has made it easier and more convenient for drivers to access their cars (via Car & Driver).
However, there are some downsides to this technology. Key fobs can be more expensive to replace if lost or damaged compared to traditional keys. Additionally, key fobs require batteries to function and can run out of power unexpectedly. This can leave drivers stranded and unable to start their cars. Despite these drawbacks, key fobs are here to stay and are likely to continue evolving as car manufacturers incorporate new technologies into them, such as proximity sensors that allow drivers to unlock their cars automatically when they approach them.
