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.
