Security

Smart keys are key fobs that are computerized and communicate with a vehicle via one of the car's embedded antennas to open doors and to start the engine. Unlike conventional keys, which emit the same frequency signal each time they are used, smart keys transmit encrypted signals that are only compatible with the car they belong to. This makes it harder for criminals with a technological edge to intercept or spoof the signal and use your key to steal your vehicle.

Certain smart keys, like those from BMW, also have user-specific settings, which allow the driver to adjust the seat, mirrors and steering wheel's location and audio preferences at the press of a single button. They also have the backup lock, which stops the vehicle from starting if it is not connected to the key.

This technology prevents drivers from locking their vehicles, particularly when they have to search their purse or backpack to find keys in a parking area packed with strangers or on an area with high crime rates.

How Stuff Works Electronics notes that modern smart keys also detect the key being used and adjust the vehicle settings accordingly. For instance, if you turn on the car while holding the key fob in your palm, the windows and sunroof can be opened to let air circulate through the cabin.
