What Can a Smart Car Key Fob Do For You? Also known as fobs, keyless entry or smart keys, they were first introduced by Mercedes in 1998. Key fobs that are controlled by computers perform many tasks, including locking and unlocking a car as well as launching it. They function by sending an encrypted message that is continuously transmitted. They are protected from thieves who are tech-savvy. Safety A smart key fob continually communicates with a vehicle through radiofrequency signals. It sends out a low-power signal that, when pressed, tells the vehicle to open doors and begin the engine. The car recognizes the unique encryption code from a specific key fob. This means that if a key fob is stolen, the car will not start. But a new type of hacking could enable thieves to gain access to that communication. Relay attacks are carried out using devices that transmit at the same frequency as the key fob. A thief can place one of these devices in a pocket or a hiding location to thwart the lock command from a distance, says How Stuff Works Electronics. This is a risk which could become more frequent, as more drivers adopt smart keys.

It can also sense when you're leaving the car and auto-lock the car, so you don't need to worry about forgetting to lock the doors. Many smart key fobs have an indicator for batteries that informs you in advance that the battery is getting low. The replacement of the battery in most models is a straightforward, easy procedure that does not require any special tools. Convenience As opposed to a traditional metal key Smart keys do NOT need to be physically inserted into an ignition slot to unlock or start a car. Rather, the driver simply requires it to be on their hands and bring it within range of the vehicle, as explained by the BMW Group. In reality, certain smart keys, including the Display Key, have small LCD touchscreen in color that allows drivers to access features such as locking, unlocking, and keyless start directly from their key fobs without needing to connect to the car's Bluetooth system. Another way that smart keys can save drivers time is by automating the process of locking their doors when they leave it. Consumer Reports says that this feature is available on many automobiles. It can also make it easier for drivers to maneuver into tight spots without accidentally squeezing someone or something. Smart key systems generally do not transmit the same frequency signal over and over and this can make them more susceptible to relay attacks, as explained by Open Road Auto Group. As such, a stolen vehicle cannot be connected to a hotwire if equipped with a smart key as the encrypted signal that the key fob transmits is unique to each vehicle. This makes it very difficult for thieves steal the car. Security Some of the top-of-the-line electronic features in today's newer automobiles can be found in the key fob. These gadgets are capable of more than just locking and unlocking doors or making chirping sounds to assist drivers locate their car in parking spaces. However, some owners may be unaware of the full capabilities. For instance, certain smart keys can trigger windows that automatically open and sunroof once they are press.

Certain smart keys use encrypted computer signals to deter car thieves according to How Stuff Works. This technology is able to prevent hotwiring in which thieves steal the vehicle's engine control unit (ECM), which is usually found in the front of the engine block. The ECM is responsible for many important functions including engine power, transmission control, and many more. Smart keys also have anti-theft codes, as well as an unique security ID code assigned to each key. This could disable the ignition if the wrong key is used. The security ID is a specific code that's transmitted from the ECM to the key once it's put in the ignition and confirmed by a device inside the car. Maintenance A smart car key fob does much more than unlock your door. It can remotely start your engine, trigger the brakes and suspension and even start your car. It also provides information about your car such as the fuel level and the oil temperature. Like any piece of electronic equipment, a smart car key fob needs regular maintenance in order to function correctly.
