Today, many new BMW vehicles come standard with a smart key system that allows you to lock and unlock your vehicle by simply pressing an icon on the steering wheel. Some models also feature remotes that allow you to start the engine and close the sunroof and windows from a distance.

This allows the key to control the car from a few meters away. The key has an RF coil that detects and transmits the remote lock signal from the car to the dashboard.

Contrary to older key fobs for cars that transmit the same frequency over and over (which could impact other models and makes using the same system, and could making it easier for tech-savvy thieves to take vehicles), modern smart keys transmit a distinct encrypted signal every time they're used to open or close a door or pop the trunk. The radio antennas in the vehicle respond by emitting the appropriate frequency to identify the key, lock it or turn it on.
