mercedes keyless go
Mercedes KEYLESS GO is a system available on most Mercedes vehicles that uses a smart key to lock and unlock the car's doors and start the vehicle without you ever having to remove the key from your pocket. The car uses antennas in the doors, fuel flap, and bumper to communicate with the key wirelessly. To open the door, you simply touch one of the door handles, and once the system has authenticated the key it will unlock the car. To lock the vehicle from the outside, you can press the lock button on any of the door handles. Once inside the car, it can be started or stopped by simply pressing the Start/Stop button.
