To bring this remarkable technology to life, we used geofencing a virtual boundary.
When users return home and enter this virtual fence, the lock automatically switches to an open-ready state.
Then, as they approach the door, it unlocks automatically, eliminating the need to enter a passcode.
Plus, you’ll have the added bonus of impressing friends with this cutting-edge technology.

PLUS LINK does not only upgrade accessories to locks. It can also upgrade the security itself.
One example is KeyinE, the Plus LOCK. Door lock ensures security when the door is closed. But what happens when the door opens? There are numerous occasions when you have to open the door unprotected. Our Creative Lab came up with a solution in which security is still enabled even when the door is opened.
With KeyinE, you have two options. Completely opening the door, or opening it secured by a door chain. And the usability is super simple. Two dedicated buttons for two situations. Simply press secured open button and the Plus LOCK will lock itself while KeyinS(the door lock) opens up. We want people to actually use it, that’s why we tried to make it as simple as it can be.
* This product works only on doors that open outwards.
