Smart Keys
Today, many of the latest BMW cars come with an intelligent key system that lets you lock and unlock your car with just a click of an icon on the steering wheel. Some models also feature remotes that allow you to start the engine and close the windows and sunroof from an extended distance. These advanced keys use radio to lock or unlock, and infrared to connect with the dashboard.
The IR circuit is the source of an infrared bridge bidirectional that transmits commands to and from the dashboard and to the receptacle in the key. The key is able to control the car from a distance of just a few metres. The key has an RF coil that picks up and transmits the remote lock signal from the car to the dashboard.
