What Is Proximity Key?
by Dan Spencer -
A proximity key (also called Intelligent Key, Keyless Go, Push-to-Start or Smart Key) is a computerized device that enables a keyless entrance and ignition mechanism in your vehicle.
When you’re within the appropriate radius, the key-less entry interacts through radio frequency waves with your engine control unit to lock and open doors and even to crank the engine having the key in the pocket.
In 1998, Mercedes-Benz was the first car-maker to implement this platform in the automotive industry.
Presently, vehicle drivers can take advantage of key-less entries and push start ignition on nearly all automobile models and enjoy functionality like alarm, power windows, mirror adjustment, remote start and many more.
