5 Common Myths About Smart Car Key Fob Replacement You Should Avoid
What Can a Smart Car Key Fob Do For You?
Mercedes introduced the first fobs in 1998. They are also known as smart keys, keyless entry, or keyless entry fobs. These fobs controlled by computers are capable of performing a variety of functions, such as locking and unlocking the car, or beginning it.
They work by transmitting an encrypted message that is continuously transmitted. This makes them more receptive to thieves who are tech-savvy.
Safety
A smart key fob continually communicates with the vehicle using radiofrequency signals. It sends a low-power signal that, when pressed tells the car to unlock doors and begin its engine. The car recognizes the unique encrypted code from a specific keyfob. This means that if a key fob is stolen, the car will not start.
However, a new kind of hacking could permit thieves to take advantage of that communication. Relay attacks are carried out using devices that transmit at the same frequency as the key fob. How Stuff Works Electronics says that a burglar could slip one of these gadgets into the pocket or hidden area to block the key fob's lock command remotely. This is a risk that is likely to become more prevalent, as more drivers adopt smart keys.

Certain smart keys, such as the Display Key, have tiny LCD touchscreen that allows drivers access to features like locking, unlocking, and keyless starting directly from their key fob without needing to connect to the Bluetooth system of the car.
A smart key can also help drivers save 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 usually do not transmit the same frequency signal repeatedly which could make them more vulnerable to relay attacks, explains Open Road Auto Group.

Security

According to How Stuff Works, some smart keys employ computer-encrypted signals to prevent car thieves from stealing. This technology can prevent hotwiring in which thieves steal the engine controller module (ECM) typically located in front of the engine. The ECM regulates a variety of vital functions including engine power, transmission control and many more.
Smart keys also include anti-theft code and a unique security code for ID assigned to each key. This will disable the ignition if the wrong key is used.
