What Can a Smart Car Key Fob Do For You? Mercedes introduced the first fobs in the year 1998. They are also known as smart keys, keyless entry or keyless entry fobs. These computer-controlled fobs are capable of performing many tasks, such as locking and unlocking the vehicle or getting it started. They function by broadcasting a rolling encrypted signal. This makes them less vulnerable to hackers with a technological edge. Safety A smart key fob constantly communicates with a vehicle using radiofrequency signals. It transmits a low power signal that, upon pressing, tells the vehicle to unlock doors and start the engine. The car can recognize the unique encrypted code of a particular keyfob. This means that even when the key fob has been stolen, it cannot be used to begin the car. A new hack allows thieves to take advantage of this communication. Relay attacks are carried out with devices that transmit at the same rate as key fobs. How www.g28carkeys.co.uk says that thieves can put one of these devices into a pocket or hidden spot to block the remote control of the lock. This is a risk that is likely to become more prevalent as more and more drivers change to smart keys. A smart key fob isn't just a security feature, but it can also simplify your life by automatically taking care of the needs of your vehicle. For example the key fob linked to your smartphone could detect your proximity and unlock the doors, meaning that you don't have to hit a button on the remote. It can also sense when you're leaving the car and auto-lock the car, so you don't need to worry about not locking the doors. A majority of smart key fobs have an indicator for batteries that tells you when the battery is not fully charged. Most models allow you to replace the battery quickly and easily without the need for any special tools. Convenience Smart keys do not have to be physically inserted in an ignition slot to unlock or start the vehicle. Instead, the user requires it to be on their hands and bring it within range of the vehicle, as described by the BMW Group. In reality, some smart keys, including the Display Key, feature a small LCD touchscreen that enables users to access features such as locking or unlocking as well as keyless start directly from their key fob without having to connect to the car's Bluetooth system. Another way a smart key can save drivers time is by automatizing the process of locking their car doors when they leave it. Consumer Reports says that this feature is available on a wide range of vehicles. It can also make it easier for drivers to maneuver into tight spaces without accidentally hitting someone or something. Smart key systems typically do not transmit the same frequency signal repeatedly which could make them more susceptible to relay attacks, as explained by Open Road Auto Group. Smart keys are specific to each vehicle, which means that a stolen car can't be connected to a hotwire. This technology makes it difficult for thieves steal the car. Security Modern cars come with more advanced electronic features than ever, and some of them are contained inside the key fob. These gadgets are capable of more than just locking and unlocking doors, or making chirping sounds to help drivers locate their vehicle in parking areas. However, some owners may be unaware of the full capabilities. Certain smart keys, for example, can activate the auto windows and sunroofs of an automobile when pressed. A Auto editor of CR once walked out to her Honda Accord only to find all the windows closed and sunroof up. This is one of the reasons she was grateful for her Smart Key, which locked the vehicle automatically. Some smart keys use computer-encrypted signals to stop car thieves, according to How Stuff Works. This technology prevents hotwiring in which thieves steal the engine controller module (ECM) which is usually located at the front of the engine. The ECM manages a range of important functions, including transmission control and engine power. Other technologies in smart keys include anti-theft code and a unique security ID that is assigned to each key, which can turn off the ignition if it's not the right one. The security ID is a unique code that is transmitted by the ECM from the key to the ignition and then confirmed by a sensor inside the car. Maintenance Smart car key fobs can do much more than unlock the door. It can remotely start your engine, activate the brakes and suspension and even start your vehicle. It also can provide information about your vehicle such as fuel level and oil temperature. Like any piece of electronic equipment smart car key fob requires regular maintenance to function properly. Modern key fobs have indicators for the batteries to inform the driver that it is time to replace the battery. Replacing the battery is a simple procedure, and no specialist tools are required. In certain instances, however, a smart key could stop functioning completely. If you suspect that this is the issue, try to reset the smart key after leaving the vehicle and returning inside. This will allow the car to detect that the key fob is still in the vehicle and let it regain functionality. Contact a locksmith in the event that you have trouble getting your key fob to work. They can reprogram it so that your vehicle recognizes it once more and allows you to utilize all of its features. This is usually cheaper than purchasing a new fob and can save you money over time. In some instances, the locksmith can fix an existing key fob to be able to exchange it for a new one. This could save you money in the end.
