Z Wave Plus Smartlock

  • Smarter user codes. This lets you retire your spare keys and replace them with four-digit user codes for family and trusted visitors. It’s easy to create a code for each of your kids, your dog walker, or a contractor who needs access. Unlike a spare key, you can easily delete a user code or give it an expiration date.
  • Awareness and peace of mind. Alarm.com-powered smart locks can generate smartphone alerts when people unlock the door with their user code. If your kids come home before you do, you can get an alert every day when they arrive. Alarm.com can even send you an unexpected activity alert if your door is unlocked at a strange time. 
  • Voice-controlled security. With Alarm.com, you can lock up at night simply by talking to your Google Home or Amazon Echo device. With our updated Alarm.com Skill for Alexa, you can securely unlock your doors too, using a Secure Command with a four-digit pin.  
  • Scenes automation. It’s easy to include an Alarm.com-powered smart lock into a Scene, where a single command controls many devices. Activate our pre-set Away Scene, for example, and your security system arms, your front door locks and your garage closes, giving you a smoother getaway from home. —with the first instance of a lost key doubtless occurring soon after.
