Hello World! Welcome Friends! A key fob is a small handheld electronic device that serves as a remote control for various functions related to vehicles. This device uses radio frequencies to allow the user to control some of a car’s functionalities without a physical key. It can be used to lock or unlock car doors, open trunks, activate car alarms, and even start the engine remotely. A key fob eliminates the need to rely on a physical key to control some of a vehicle’s functionalities and offers more convenience. Besides, these devices enhance a car’s security.
While key fobs have become an integral part of modern cars, it’s surprising how many people use them without a clear understanding of their inner workings. Here at QuickPro Locksmith, we understand how key fobs work thanks to our expertise and industry experience. If you’re looking for a professional locksmith in Smyrna to help you with key fob programming or car key replacement, look no further than QuickPro Locksmith. Read on to understand how key fobs work.
How Does a Key Fob Work?
A key fob works through radio frequency identification (RFID), which is an intelligent barcode system that uses electromagnetic fields to locate or identify stored information known as tags. The key fob contains a transmitter and an integrated circuit that stores encrypted codes unique to the receiver device. When you press a button on the key fob, the device sends a distinct code to the receiver in the car. The receiver, whether it’s a car’s door lock or alarm system, checks the validity of the code. If the code matches, the receiving system performs the requested action, such as unlocking doors, activating the alarm system, unlocking the truck, or starting a car’s engine. The distinct code has to match what the receiving system has been programmed to accept. If there’s a mismatch, the function will not be performed. Key fobs provide an added layer of security by performing the requested function only when the distinct code matches what the receiver is programmed to accept.
Uses of a Key Fob
- Key fobs are widely used to remotely lock, unlock, and start vehicles, eliminating the need for physical keys.
