What Can a Smart Car Key [Valetinowiki.Racing] Fob Do For You? Also known as fobs, keyless entry or smart keys, they were introduced by Mercedes in 1998. Key fobs that are computer controlled can perform a variety of functions, including locking and unlocking a vehicle as well as launching it. They function by broadcasting an encrypted and rolling signal. This keeps them safer from tech-savvy thieves. Safety A smart key fob communicates with a vehicle via radiofrequency waves. It transmits a low power signal that, when pressed it, prompts the vehicle unlock doors and start the engine. The car recognizes the unique encryption code from a particular keyfob. This means that if the keyfob is stolen, the car is unable to be started. However, a new kind of hacking technique can enable thieves to gain access to that communication. Relay attacks are carried out using devices that transmit at the same frequency as a key fob. How Stuff Works Electronics says that a thief could place one of these devices in an unnoticed pocket or a hidden location to stop the remote control of the lock. This issue could become more commonplace as more people switch to smart keys. Aside from these security features, an intelligent key fob could make life easier by automatically tending to your vehicle's needs. For example a key fob connected to your smartphone can detect your presence and then unlock the doors, so you don't need to push a button on the remote. It can also recognize that you're leaving the vehicle and automatically lock it, so you will not forget to lock the doors. A majority of smart key fobs have an indicator for batteries that tells you when the battery is not fully charged. Also, replacing the battery in the majority of models is a simple and simple procedure that does not require any special tools. Convenience Unlike a traditional metal key smart keys do not need to be physically inserted into an ignition slot in order to unlock or start a car. Rather, the driver simply requires it to be in their possession and be able to bring it within range of the vehicle, as described by the BMW Group. Some smart keys, like the Display Key, come with an incredibly small LCD touchscreen that grants drivers access to features such as locking, unlocking and keyless starting directly from their key fob, without the need to connect the Bluetooth system in the car. A smart key can also save drivers time by automating the closing of their car doors when they leave. Consumer Reports says that this feature is available on many vehicles. It also makes it easier for drivers to maneuver into tight spaces without accidentally hitting the door or something else. Furthermore, smart key systems do not typically send the same frequency signal repeatedly, as this could make them more vulnerable to relay attacks, according to Open Road Auto Group. Smart keys are unique to each vehicle, which means that a stolen car can't be hotwired. This technology makes it extremely difficult for thieves to steal a car. Security Modern cars come with the most advanced electronic features ever before, and some of those are located in the key fob. These devices are capable of much more than locking and unlocking doors, or making chirping noises to help motorists locate their car in parking areas. However, some owners may be unaware of the full capabilities. Some smart keys, for example, can activate the auto windows and sunroofs of an automobile when they are pressed. A auto editor for CR once went out to her Honda Accord only to find all the windows closed and the sunroof opened. She was thankful for her Smart Key that automatically locked the car. Some smart keys use computer-encrypted signals to stop car thieves according to How Stuff Works. This technology can prevent hotwiring in which thieves steal the engine controller module (ECM) which is usually located at the front of the engine. The ECM regulates a variety of essential functions, including transmission control and engine power. Smart keys also come with anti-theft codes and a unique security code for ID assigned to each key. This can disable the ignition if the wrong key is used. The security ID is a code that is transmitted by the ECM from the key to the ignition and then confirmed by a sensor located in the car. Maintenance A smart car key fob does more than just unlock your door. It can remotely start your engine, trigger the brakes and suspension and even start your vehicle. It also provides information about your car including the level of fuel and the oil temperature. Like any piece of electronic equipment smart car key fob requires regular maintenance in order to function correctly. Modern key fobs feature indicators for the batteries to inform the driver when it's time to replace the battery. It's simple to replace the battery and you don't need any special tools. In some cases the smart key may stop working completely. If you suspect that this is the case attempt to reset the smart key by removing the vehicle and coming back inside. This will help the car recognize that the fob is still in place and allow it to get back to its normal function. Contact a locksmith if you have trouble getting the key fob to work. They can reprogram it to ensure that your car recognizes it again and allows you to utilize all of its features.
