What Can a Smart Car Key Fob Do For You?

Known as fobs or keyless entry or smart keys, they were first introduced by Mercedes in 1998. The fobs that are computer controlled are capable of performing a variety of functions including locking and unlocking the vehicle or starting it.

Safety

A smart key fob continually communicates with a vehicle, via radiofrequency waves. It emits a low power signal that, upon pressing the button, instructs the vehicle to open doors and start the engine. The Car fob programming is programmed to recognize the unique encrypted code of a specific key fob. This means that if the keyfob is stolen, the car cannot start.

But a brand new type of hack can permit thieves to take advantage of that communication. Relay attacks are based on devices which transmit on the same frequency as the key fob. How Stuff Works Electronics says that thieves could put one of these devices inside an unnoticed pocket or a hidden location to block the lock command remotely. This is a problem that could become more frequent, as more drivers are switching to smart keys.

Another way that smart car replacement key keys could help save time for drivers is by automating the process of locking their doors when they leave it. This feature is found in many vehicles, according to Consumer Reports, and can also help get into tight parking spaces without accidentally squeezing something or anyone.

Furthermore, smart key systems do not typically send the same frequency signal repeatedly, as this could make them more susceptible to relay attacks, says Open Road Auto Group. Smart keys are specific to each vehicle which means that a stolen car can't be hotwired. This technology makes it difficult for thieves steal cars.

Security

Today's newer cars pack in more advanced electronic features than ever before, and some of them are housed in the key fob. These devices are capable of more than locking and unlocking doors, or making chirping sounds to help drivers locate their vehicle in parking spaces. However many owners are unaware of the full capabilities.

Certain smart keys, for example, will trigger the auto windows and sunroofs of the vehicle when they are pressed. A CR auto editor once walked out to her Honda Accord only to find all the windows closed and the sunroof opened. This was one of the reasons she was so grateful for her Smart Key, which locked the vehicle automatically.

According to How Stuff Works, some smart keys utilize computer-encrypted signals to stop car thieves. This technology stops hotwiring, where thieves steal the vehicle's engine control unit (ECM), that is usually located on the front of the engine block. The ECM controls a variety of vital functions, such as engine power and transmission control.

Other technologies used in smart forfour key keys include anti-theft code and a unique security ID 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 validated with a sensor in the car.

Maintenance

In some instances, the smart key will cease to function completely. If you suspect that this is the case, you can reset it by taking the car out and then coming back inside. This will enable the car to understand that the key fob is still inside the vehicle, and allow it regain functionality.

If you're not able to make your fob work get in touch with a locksmith for help. They can reprogram your fob so that it is recognised by the car and you can make use of all its features.
