The ViperKey system replaces your car key or key fob, and automatically unlocks your door as you approach. As long as you have your phone in your pocket, the ViperKey will let you slide into your car without having to touch a button. Once you exit, ViperKey will automatically lock your doors — ideal for OCD types who are always concerned someone is going to jack their sweet Mazda Miata from the Target parking lot. No need to launch an app, and no need to do anything other than grab the door and go.
