Many of the latest BMW models are equipped with a smart-key system that lets you lock and unlock your car by simply pressing the steering wheel. Additionally, certain models also come with a system that lets you start the engine from a distance and also remotely close the windows and the sunroof. These advanced keys use radios for locking and unlocking and infrared (IR) to communicate with the dashboard.

The IR circuit is the source of a bidirectional infrared bridge that sends commands from and to the dashboard, and also to the receptacle inside the key. This lets the key control the car from a few meters away. The key is equipped with an RF coil which picks up and transmits the remote signal for locking from the car to the dashboard.

These smart keys also store information, such as power seat and mirror settings. To share access with someone else, you need to connect the key with an iPhone and then follow the directions on your device. This will allow you to share a digital key that works as long as the phone is running and in Bluetooth range.

Modern smart keys, as opposed to older car keys that transmit the same frequency repeatedly (which could affect cars using the same system, making it easier for criminals with tech skills to take cars), broadcast a different encrypted message each time they're used to open or shut a door or pop out the trunk.
