This keyless lock can be fitted to most single-cylinder deadbolts so you can carry on using your existing hardware and your keys when you want to. It attaches easily to the existing deadbolt of the door so it only takes around 10 minutes to fit and you only need a screwdriver.
It needs four AA batteries and offers completely flexible access – you can grant access for weeks, days or hours at a time and it automatically opens as you approach with your smartphone. When you leave home, the door will lock behind you either instantly or up to 30 minutes later. The device is compatible with Alexa, Google Assistant and many other smart security systems.
