How Key Fobs Work: A Detailed Guide from Locksmith in Dubai

Aug-11-2023 | By Admin

A key fob is a small programmable device that provides easy excess to your car, office, or house. It provides on-device, one-factor authentication to facilitate easy access to a device or system such as computer system, car, mobile device, restricted room or areas, network services among many other keyless entry systems. With a key fob, you don’t have to unlock the devices with a real key or new lock installation as is the case with manual locks.

More so, key fobs also allow remote access, meaning you can allow someone to access your car, or restricted room even when you are you are not close to your device. So, besides being more secure, key fobs are also more convenient.

How does a key fob works?

Now that you know what a key fob is, the next question in your mind is: how do they work? Key fobs are equipped with a short-range radio frequency identification antenna and chip. They use radio frequencies to transmit a unique coded signal to a receiver that is unique to the device. The receiver also contains the radio frequency identification tag, which is basically some form of stored information.

When you click the transmitter it sends signals to the fob, which in turn adjust the transmitter frequency. It is important to note that the communication between the key fob and the receiver happens instantly when the user presses the key fob.

The radio frequency identification chip on the fob is designed to transmit specific radio frequency identification tag data. The signal will only be transmitted successfully if the data on the key fob matches with the receiver device that has been programmed to access the signal.

For instance, when a key fob is programmed to work on a certain car, it will only lock and unlock that particular car and no other key fob can work on that car. This is because for a key fob to function, the information on the key fob must match with the receiver tag. If there is a mismatch, then locking and unlocking will not be successful.

Key fobs can be programmed to perform various functions. For instance, in cars, key fobs can be used to lock and unlock the car, start the ignition, and control automatic windows.

What are key fobs used for?

The main uses of a key fob include:

Locking and unlocking the car door system
