What Can a Smart Car Key Fob Do For You? Mercedes introduced the first fobs back in 1998. They are also known as smart keys, keyless entry or keyless entry fobs. These computer-controlled key fobs can perform many tasks, including locking and unlocking a vehicle as well as launching it. They operate by broadcasting a rolling encrypted signal. This helps protect them from thieves who are tech-savvy. Safety A smart key fob continuously communicates with a vehicle, through radiofrequency signals. It emits a low power signal that, upon pressing it, signals the vehicle to unlock doors and start the engine. The car can recognize the unique encrypted code from a particular keyfob. This means that even when the key fob is stolen, it can't be used to start the car. But a new type of hacking technique can permit thieves to take advantage of that communication. Relay attacks are carried out with devices that transmit at the same rate as keys. How Stuff Works Electronics says that a burglar could slip one of these devices in pockets or in a hidden place to block the remote lock command. This is a problem which could become more frequent as more and more drivers change to smart keys. Apart from these security options, a smart key fob can simplify your life by automatically attending to your vehicle's needs. For example a key fob linked to your smartphone can detect your presence and then unlock the doors so that you don't need to push the remote button. It can also sense when you're leaving the car and auto-lock the car, so you don't have to worry about forgetting to lock the doors. A lot of smart key fobs come with a battery indicator which warns you when the battery is depleted. Most models allow you to replace the battery quickly and conveniently without any tools or equipment required. Convenience As opposed to a traditional metal key Smart keys do not need to be physically inserted into the ignition slot to unlock or start a vehicle. Instead, the driver has to put it on their person and be able to bring it within range of the vehicle, as explained by the BMW Group. In reality, some smart keys, including the Display Key, come with small LCD color touchscreen that allows drivers to access features such as locking or unlocking and keyless start right from their keys without having to connect to the car's Bluetooth system. Another way a smart key can help save time for drivers is by automatizing the process of locking their doors after they leave. Consumer Reports says that this feature is offered on a number of automobiles. It also makes it easier for drivers to maneuver into tight spots without accidentally squeezing someone or something. Additionally, smart key systems generally do not transmit the same frequency signal repeatedly, as this could make them more vulnerable to relay attacks, as explained by Open Road Auto Group. So, a stolen vehicle cannot be hotwired if it is equipped with a smart-key because the encrypted signal that the key fob transmits is unique to each vehicle. This technology makes it difficult for thieves to steal cars. Security Some of the top-of-the-line electronic features in today's modern automobiles are included in the key fob. These gadgets do much more than just lock and unlock doors, or make chirping sounds that assist drivers in finding their vehicle in a parking lot, but some owners may not be aware of all that these smart key fobs can accomplish. Certain smart keys, for instance, will activate the automatic windows and sunroofs on an automobile when pressed. A auto editor for CR once went out to her Honda Accord only to find all the windows shut and the sunroof up. She was thankful for her Smart Key that automatically locked the car. According to How Stuff Works, some smart keys employ computer-encrypted signals to stop car thieves. This technology can prevent hotwiring in which thieves steal the engine controller module (ECM) which is typically located in front of the engine. G28 is responsible for a variety essential functions, including engine power and transmission control. Smart keys also come with anti-theft codes as well as a unique security ID code assigned to each key. This can disable ignition when the wrong key is used. The security ID is a number that is transmitted by the ECM from the key to the ignition and then verified by a sensor inside the car. Maintenance Smart car key fobs can do more than just unlock the door. It can remotely start your engine, turn on suspension and brakes, and even start your vehicle. It can also provide information about your vehicle like fuel level and oil temperature. Like any piece of electronic equipment, a smart car key fob needs regular maintenance to ensure it functions correctly. Modern key fobs come with indicators for the batteries to inform the driver when it is time to replace the battery. It's simple to replace the battery and you don't require special tools. In certain situations, however, a smart key can stop working completely. If you suspect this is the case try resetting the smart key by removing the vehicle and then returning to it. This will enable the car to understand that the key fob remains inside the vehicle, and allow it regain functionality. If you're not able to connect your fob call a locksmith help. They can reprogram the fob to ensure that it can be recognized by your car and you can make use of all its features. It's generally cheaper to do this than buy the new fob for your key, and it will save you money in the long run. In some instances, the locksmith can fix an existing key fob to be able to swap it to purchase a new one. This can save you even more money in the long run.
