They also have features that are specifically designed to stop burglaries and theft of vehicles, such as panic buttons, which produces a sound to frighten away people who might be a threat to thieves or in areas that are isolated, such as underground garages that are parking.

Key fobs accomplish all of these functions by sending radio signals between the car and the key fob via low-power wireless technology. This is a fantastic feature, especially for drivers who are on the move and do not have much time.

A smart key is usually designed to look more like a plastic card than an actual key, and it can be used to open the trunk or car's doors when a button on the fob is pressed. Certain smart keys come with touchscreens that allow drivers to control the vehicle's settings, like audio and climate.

The RFID signal sent between the key fob and a car is distinct, encrypted, and tied to the onboard computer this makes it virtually impossible for hackers with the latest technology to hotwire a stolen vehicle equipped with one. The fobs can also be programmed to transmit a new frequency signal each time they're used, meaning the computer in the car won't be able to recognize an old one as the "true" signal.

Security

Many people are hesitant adopt digital keys as they are worried about security. While having a physical key fob at hand does feel more secure, it's important to recognize that digital keys are also more secure than you might think.

This is useful if you have multiple drivers or wish to restrict certain features when you loan your car to a novice driver.

Another benefit of smart keys is that they employ encryption to prevent theft, which isn't a possibility with traditional keys. This technology makes it extremely difficult for tech-savvy thieves to steal a vehicle by imitating an authentic frequency signal, reports How Stuff Works Electronics. Smart keys transmit a unique encrypted message each time the vehicle's remote or unlocked.

The battery of a smart key will eventually run out like any other battery-operated device. The majority of systems have backup systems to unlock the car and begin it if the battery is not able to function. The emergency method can vary however, it is usually holding the key within the proximity to the lock sensor on the car or pressing a button that activates the emergency starter.

The transmitter is integrated into the key fob is carried with you and the receivers are located in your vehicle as well as around the outside of it. The receivers pick up the radio frequency signal that is sent by your smart key when you approach the vehicle and activate the ignition and doors.

While this system comes with many advantages, including not having to search in darkness to find a key, it can be vulnerable to certain types of attacks. How Stuff Works Electronics reports that if the battery of your key dies or is lost, someone could pick up the low frequency transmission signal and gain access to your vehicle. Most smart keys have encrypted signals, which makes hacking more difficult.

If you notice that the smart key fob you purchased does not work as expected, it could be due to an issue with interference. In this instance, you shouldn't put your key in proximity to such devices until the battery of the device has been replaced.
