Types of Key Fobs
In a lot of modern vehicles, key fobs are utilized to replace traditional keys made of plastic or metal. They offer a variety of convenient features which can make driving more comfortable and easier. Key fobs are small remote controls that transmit commands to the locking systems on doors and ignition via radio frequency. Fobs can also be used with smartphone applications to unlock and open your vehicle from any location, provided you have the app and key fob within reach.

The emergency key is a metallic key that slides into and out of the key fob. It can be used to start the engine as well as control the car's controls.

Another type of key fob is a passive one that doesn't require presses to unlock or begin the car. These aren't as popular as active key fobs because they have a shorter battery life and can be harder to track. Key fobs that use this design have an active sensor that detects close proximity to the vehicle and sends a signal to the receiver. The car's receiver checks to see if it matches the ID code that is stored in its memory. This is what allows the car to be unlocked and begin.
Future car key fobs for keys will likely have more features. They will integrate with smart home systems, and other IoT devices to aid people in managing their cars and daily lives. They could also come with more security features, like anti-hacking technologies and advanced encryption.

If you do not follow these steps exactly, your car might not recognize the keyfob or the communication between them could be distorted.
