Key Fob Not Working Here’s What You Can Do

People usually forget to lock their keys when in a rush. It was hard to ask to wiggle a metal key in the lock every time. A key fob is developed by using advanced technology for people’s ease. It is a perfect example of wireless technology that we use in our daily life. However, only a few people give it a thought.

What is a Key Fob?

The word FOB stands for “Free On Board.” A key fob is similar to a small remote control. You can call it a keyless remote control system, as it is used to lock and unlock your car without directly using the key. It consists of a built-in authentication system that helps secure your car.

A key fob uses radio frequencies to communicate with your car. You have to press the button to hear a chirping sound. It assures you that the car is locked or unlocked now.
