What Is Key Fob, And Why You Need It

Posted by Keyless Entry Remote on May 11th 2021


Today, if you buy a new car, you can expect it to come with a keyless entry system and a remote control to operate that system. The remote control is often referred to as a key fob. By definition, it is referred to anything that is used on a keychain for decoration or functionality, but most of the time, when this term is used, it refers to the keyless remote. They have become as much of a status symbol as anything else, but knowing exactly how they work can go a long way.

The Evolution of Key Fob

Not long after the invention of the keyring, people began adding other useful accessories to keyrings other than just their keys; that was how the key fob was born.  People often carry key fobs along with keys on a ring or chain. These fobs were initially developed as small weapons. But nowadays, they are mainly used as decorative items and are purely aesthetic. They are also modified to be used as small tools or to give a better grip. There is a large variety of key fobs available in different sizes, styles, and functionalities. 

How Does Key Fob work

A key fob works like many other basic remote control systems. In the remote control is a computer chip that creates a unique code that the receiver is programmed to recognize. You don't have to worry about someone being able to replicate this code because a standard 40-bit rolling code is choosing from a trillion possibilities. Also, the code used by the system is not always the same, and consequently, the remote control and the receiver must be synchronized. This is done after installing the keyless entry system, so there is no need to worry about it.

How to use key fob 

One issue can occur from this key fob style, if you press the remote and are not close enough to the cars for the receiver to pick up the transmission, then the two won’t be synchronized. This problem is resolved very quickly because a typical system will have many other codes that it will accept after de-synchronization (usually 256). 
Nevertheless, this suggests that if you press the remote 257 times while not in range of the car, you might have a problem because the remote has no appropriate codes delegated attempt. In this case, you will need to reprogram the system; the procedure differs by make and models of the vehicle, and that can be discovered online.

Keep in mind that since this innovation is so complex,  keyfobs are not interchangeable and can not be copied. You need to take good care of it because if you lose or break it, then a new one will have to be purchased and programmed. This will be at another cost; however, it depends on the type of car you have.
