What Can a Smart Car Key Fob Do For You? Mercedes introduced the first fobs in 1998. They are also referred to as smart keys, keyless entry or keyless entry fobs. These computer-controlled key fobs can accomplish many things, including locking and unlocking a car and also starting it. They function by sending an encrypted and rolling message. They are protected from hackers with a technological edge. Safety A smart key fob is constantly communicating with the vehicle via radiofrequency waves. It sends a low-power signal that, when pressed will instruct the car to open doors and begin its engine. The car recognizes the encrypted code that is generated by a specific key fob. This means that even when the key fob has been stolen, it won't be used to begin the car. But a brand new type of hack can let thieves exploit this communication. Relay attacks are carried out with devices that transmit at the same frequency as the key fob. A thief can place one of these devices in a purse or hiding location to thwart the lock command from a distance, according How Stuff Works Electronics. This is a risk that could become more frequent as more motorists are switching to smart keys. Apart from these security features, the smart key fob can simplify your life by automatically tending to the needs of your vehicle. For instance the key fob linked to your smartphone could detect your presence and open the doors so that you don't have to press a button on the remote. It can also detect the moment you leave and automatically lock the vehicle, so you don't have to fret about not locking the doors. Many smart key fobs also have an indicator for the battery that alerts you ahead of time when the battery is at a low level. The majority of models let you replace the battery quickly and easily without any tools or equipment required. Convenience Smart keys do not need to be inserted physically into an ignition slot to unlock or start the car. Instead, the driver needs to have it on their hands and bring it within the range of the vehicle, as explained by the BMW Group. In reality, some smart keys, including the Display Key, come with an extremely small LCD color touchscreen that allows drivers to access features such as locking and unlocking, as well as keyless start right from their key fob, without having to connect to the car's Bluetooth system. Another way that smart keys could help save time for drivers is by automatizing the process of locking their car doors when they leave. Consumer Reports says that this feature is present on a variety of automobiles. It can also make it easier for drivers to maneuver around tight spots without accidentally pushing someone or something. Open Road Auto Group explains that smart key systems do not transmit the same frequency signal repeatedly which can make them more susceptible to relay attacks. Smart keys are specific to each vehicle so a stolen car cannot be connected to a hotwire. This makes it extremely difficult for thieves to steal a car. Security Some of the high-tech electronic features found in the latest automobiles are contained in the key fob. These devices do much more than just lock and unlock doors, or emit chirping sounds to assist motorists in finding their vehicle in a parking lot, but some owners may not be aware of everything that smart key fobs are able to do. Certain keys, such as instance, will activate the automatic windows and sunroofs on an automobile when you press. One auto editor in CR walked into her Honda Accord to find the windows closed and the sunroof open. She was thankful for her Smart Key that automatically locked the car. According to How Stuff Works, some smart keys use computer encrypted signals to stop car thieves. This technology prevents hotwiring, in which thieves take the engine control module (ECM) which is typically located in the front of the engine block. The ECM is responsible for many important functions like engine power, transmission control, and more. Smart keys also have anti-theft codes, as well as an unique security code for ID assigned to each key. This will disable the ignition when the wrong key is used. The security ID is a unique code that is sent from the ECM to the key when it's put in the ignition, and is verified by a sensor inside the car. Maintenance Smart car key fobs can do more than unlock the door. It can remotely start your engine, trigger the brakes and suspension and even start your car. It can also provide information about your car, including the level of fuel and the temperature of your oil. A smart car key fob, just like any other electronic device requires regular maintenance in order to function properly. Modern key fobs include battery indicators to alert the driver when it's time to replace the battery. Replacing the battery is a simple procedure, and no special tools are required. In some instances the smart key might stop working completely. If you suspect that this is the problem attempt to reset the smart key after leaving the vehicle and then returning to it. This can help the car recognize that the fob is present and allow it to be functional again. Contact www.g28carkeys.co.uk if are not able to get your key fob to work.
