Vehicle Smart Key Technology

The smart key technology that is found in vehicles enables drivers to unlock and start their car by simply rubbing the door handle or placing the key into the pocket. It also allows for many other adjustments, including the position of the seat, internal temperature settings and mirror positioning.

However, this could result in security issues.

Security

Smart keys are key fobs with computers that communicate with a vehicle through one of the antennas that are embedded in the vehicle to unlock doors and begin the engine. In contrast to conventional keys that emit the same frequency signal every time they are used, smart keys transmit encrypted signals that are only compatible with the specific vehicle they belong to. This makes it more difficult for thieves who are tech-savvy to fake or intercept the signal and use the key to take your car.

Mercedes' Keyless Go system for instance, comes with an internal transponder that can identify the driver's keys. The Smart Key automatically unlocks and opens the doors and tailgate when it is within 1.5 meters. It also turns on the engine by pressing a button on its key.

Additionally some smart car key reprogramming keys- like those from BMW come with individual user settings that allow the driver to adjust the mirrors, seat and the steering wheel's position as well as audio preferences at the push of the button. They also have a backup lock that prevents the vehicle from starting if the key is not in the ignition.

This technology prevents drivers from accidentally locking their cars, particularly when searching through a purse or backpack for keys in a parking space packed with people or on a busy street with high crime rates. Many systems will also alert drivers when the battery of their key is low, though this feature may differ from manufacturer to manufacturer.

The smart car key programmer key also makes use of rolling codes to prevent hacking attempts and cloning, reports BMW. The computer inside the vehicle reads the code and confirms it prior to launching the engine. Most systems have a physical backup in the form of an unnoticed key blade.

If you turn on the vehicle while holding the key in your hands, for example windows and sunroof can be opened to allow fresh air to enter the interior. You can also set up an automatic speed limit that will only be applied when the car is powered by the selected key. This feature is beneficial if you're lending your vehicle to a driver who has little experience.

Battery Life
