BMW i remote App. Ok not e everyone has a BMW i but again this just shows you where this technology is going. If you did own a that car you can check the status of your car. You can lock the doors, and get alerts when it’s time for a service.
The potential is that your Watch will be the key to your car some day. When you walk up to the car, it will unlock and start up remotely. As you leave the car it will lock up automatically
