They function by sending a rolling encrypted message. This helps protect them from tech-savvy thieves.

Safety

A smart key fob constantly communicates with the vehicle through radiofrequency signals. It transmits a low power signal that, upon pressing the button, instructs the vehicle to unlock doors and begin the engine. The car can recognize the unique encrypted code from a specific keyfob. This means that even when the key fob is stolen, it cannot be used to begin the car.

A new hack allows thieves to exploit this method of communication. Relay attacks are carried out with devices that transmit at the same rate as a key fob. How Stuff Works Electronics says that a thief could place one of these devices inside the pocket or hidden area to block the remote control of the lock. This is a risk that could become more frequent as more and more drivers change to smart keys.

A majority of smart key car key fobs have a battery indicator which warns you when the battery is running low. Most models allow you to replace the battery quickly and easily, without the need for any special tools.

Another way smart keys can help save time for drivers is by automatizing the process of locking their doors when they leave it. This feature is offered in a wide range of vehicles, according to Consumer Reports, and can also make it easier to get into tight parking spaces without causing injury to something or someone.

Open Road Auto Group explains that smart key systems don't transmit the same frequency signal in a series of in order to make them more vulnerable to relay attacks. Smart keys are unique to each vehicle, so a stolen vehicle can't be connected to a hotwire. This makes it extremely difficult for thieves to steal a car.

Security

The latest cars are equipped with more advanced electronic features than ever before, and some of them are found inside the key fob. These gadgets are capable of more than locking and unlocking doors or making chirping sounds to help motorists locate their car in parking areas. However there are some who are unaware of the full capabilities.

For instance, certain smart keys can trigger the auto windows of a car and sunroof when pressed. One auto editor from CR was able to walk into her Honda Accord to find the windows completely shut and the sunroof wide open. This is one of the reasons she was thankful for her Smart Key, which locked the vehicle automatically.

According to How Stuff Works, some smart keys make use of computer-encrypted signals to stop car thieves. This technology can prevent hotwiring in which thieves steal the engine controller module (ECM), usually located at the front of the engine. The ECM controls a variety of essential functions, including transmission control and engine power.

Other smart keys' features include anti-theft codes and a unique security ID that is assigned to each key. This can block the ignition if it's not the right one. The security ID is a number that is transmitted by the ECM from the key to the ignition, followed by verification with a sensor in the car.

If you're unable to make your fob work get in touch with a locksmith for assist. They can reprogram it to ensure that the car can recognize it again and allows you to utilize all of its features.
