Today, many new BMW cars come with an intelligent key system that allows you to lock and unlock your vehicle with just a click of an icon on the steering wheel. Certain models also come with a remote system that allows you to start the engine and shut the sunroof and windows from the distance. These advanced keys use radio for locking or unlocking and infrared (IR) to communicate with the dashboard.
The IR circuit powers an infrared bridge bidirectional that sends commands to and from the dashboard and to the receptacle in the key. The key is able to control the car even at a distance of few meters. The key also has an RF coil that detects the remote lock signal of the car and transmits it to the dashboard.

The vehicle's embedded antennas then respond by emitting a specific frequency in order to identify the key and allow it to unlock or start it.
Hacking is possible but not impossible. A skilled professional could intercept the IR transmissions and gain access to your vehicle.

If you lose your keys, be sure to have your VIN number and government ID handy in case you need an replacement.
