What's a Key Fob?

A key fob is a Keyless Entry Remote Transmitter configured with authentication protocols or mechanisms to provide access to a physical object like computer systems or automobiles. They are known as hardware tokens when used on computer systems while automobile engineers and mechanics call them car key Fob(s).
However, there is a misconception about Fob among non-professionals. Some think it has the same meaning as F.O.B. (Free On Board), which is a term used in commerce to represent a Sales and Purchasing Agreement (SPA) that can be concluded without payment at the time of shipment.
In this article, we explained what a key fob is, how it functions, and how you can take advantage of the technology to fortify the security system of your automobile.

A Brief History of the Key Fob

Before diving into its history, it is good to understand that the key Fob is the same thing as the remote keyless system (RKS) or remote central locking systems. It is an electronic remote control that consists of a transmitter and a receiver inside the vehicle. It works just like the standard car key by authorizing access through radio transmission without physical contact.
With a key fob, all you need is to press a button on the remote and the vehicle will be locked or unlocked.
The history can be traced to the 1800s and early 1900s when an ornament attached to a pocket-watch chain was known as a fob. But in 1980, it was introduced as a nickname to the Keyless Entry System in vehicle models like Mercury Cougar, Ford Thunderbird, Lincoln Continental Mark VI, etc.
However, the terms fob and key fob gained prominence in 1989 when General Motors introduced the remote keyless systems using a handheld transmitter in their car models. And till date, it has widespread acceptability by all automotive manufacturers in the world.

How Key Fob Works

Key fob or keyless remotes have a built-in Radio Frequency Identification (RFID) system. The device works through electromagnetic waves and should be within a certain range of about 5–20 meters to communicate with a specific vehicle. It locks or unlocks the door by sending a coded signal via electromagnetic field or radio waves to a receiver unit in the car.
Most modern cars use fob with a frequency of 315MHz and 433.92MHz. The more sophisticated fob systems use encryption to prevent thieves from intercepting and spoofing the signal.
There is a growing demand for vehicles with key fobs or remote keyless entry systems and if your car is still using the manual systems, you need to consider an upgrade.

This is The Right Time to Integrate a Two-Factor Authentication in your Car!

Yes, you can optimize the security of your vehicle by integrating a Multifactor Authentication (MFA) system. This is the next level of security which enables the key fob to provide easier, more robust counterfeiting protection for your car and other valuables.
With a duo security or Two-Factor Authentication, you will not only spook a burglar or a thief into fleeing the scene but you will take the security of your car to the next level.
