vehicle smart key (https://yogaasanas.science/) technology allows drivers to unlock and start the car by grabbing the door handle or placing the key in the pocket. It also permits a variety of other adjustments like seat positions, internal temperature settings, mirror positioning and stereo presets.

Security

Smart keys are key fobs that are computerized that communicate with the vehicle via an embedded antenna to unlock doors and activate the motor. Smart key fobs, unlike traditional keys that emit the same frequency every time they're used, transmit encrypted signals which are only compatible with the car to which they belong. This makes it harder for criminals with a technological edge to intercept or spoof the signal, and then use your key to steal your vehicle.

Mercedes' Keyless Go system for instance, comes with an internal transponder that can identify the driver's key. When the Smart Key comes within 1.5 meters of a car it will automatically unlock the tailgate and door and starts the engine when the key's button is pressed.

Furthermore certain smart keyslike those made by BMW come with individual user settings that let the driver adjust the seat, mirrors and the steering wheel's position and audio preferences at the click of the button. They also come with a backup lock that prevents the vehicle from starting if it is not connected to the key.

This technology helps drivers avoid accidentally locking their vehicles particularly when they are searching bags or purses for keys on a parking lot with strangers or a busy street where crime is high.

The smart key also employs rolling codes to ward off hacking attempts and cloning, says BMW. The computer inside the vehicle detects the code and verifies it prior to launching the engine. Most systems come with a mechanical backup in the form of a hidden key blade.

How Stuff Works Electronics notes that modern smart keys can be able to detect keys used and adjust the car settings in line with the use of the key. For instance, if you turn on the car while holding the key fob in your palm the windows and sunroof open to let air circulate through the cabin.

To activate it, hold the lock button down and then press the unlock button.

The computer in the car will check the code every millisecond after the smart key is placed. BMW also has a similar system with its Display Key, which includes an LCD touchscreen on the smart key for smart car for added convenience, and allows drivers to lock, unlock, and start their vehicles without ever taking the key from their pockets.
