" Smart key is an electronic access and authorization system which is available as an option or standard in several cars. It was first developed by Siemens in the mid-1990s and introduced by Mercedes-Benz under the name "KEYLESS GO" in 1998 on the W220 S-Class. Daimler-Benz filed the first design patents for KEYLESS GO on May 17, 1997 in German patent offices.
The smart key allows the driver to keep the key fob in their pocket when unlocking, locking and starting the vehicle. The key is identified via one of several antennas in the car's bodywork and a radio pulse generator in the key housing. Depending on the system, the vehicle is automatically unlocked when the door handle, trunk release, or an exterior button is pressed. Vehicles with a smart key system fitted are required to have a mechanical backup[citation needed], usually in the form of a spare key blade supplied with the vehicle. Some manufacturers hide the backup lock behind a cover for styling.
Vehicles with a smart key system can disengage the immobiliser and activate the ignition without inserting a key in the ignition, provided the driver has the key inside the car. On most vehicles this is done by pressing a starter button or twisting an ignition switch.
Smart is another word for intelligence.
