Security
Smart keys are computerized key fobs which communicate with the vehicle through an embedded antenna. It can unlock doors and activate the motor. In contrast to conventional keys that emit the identical frequency signal each time they are activated, smart keys transmit encrypted signals that only match the specific car they belong to. This makes it much more difficult for hackers with the latest technology to intercept or spoof the signal, and use your key to steal your vehicle.
For instance, Mercedes' system -- called Keyless Go -- has an internal transponder which can identify the driver's keys. When the Smart Key comes within 1.5 meters of a car it instantly unlocks the door and tailgate, and the engine starts when a button on the key is hit.
Furthermore certain smart keys- like those from BMW -- have individual user settings that allow the driver to adjust seat, mirrors and the steering wheel's position as well as audio preferences at the touch of one button. They also have a backup lock that prevents the vehicle from starting if it is not connected to the key.
This technology assists drivers from accidentally locking their cars, especially when they have to search their purse or backpack for keys in a parking lot packed with strangers or on a busy street with high rates of crime. Many systems also alert motorists when their keys are not fully charged, however this feature differs by manufacturer.

Modern smart keys also recognize the key that is being used and adjust the settings of the vehicle in line with the use of the key, says How Stuff Works Electronics. If you switch on the vehicle while holding the key in your palm, for example the windows as well as the sunroof can be opened to allow fresh air to enter the interior.

To activate it, press the lock button until you release it and press the unlock button.
This will prevent your smart key fob's smart device from being able to transmit or receive radio waves. This will significantly extend the life of your battery. You can always restart this function by pressing the unlock and lock buttons once more.
