The motorised cylinder lock, known as Gear, allows for a smart house entrance door. In fact, thanks to the Bluetooth interface, the door can be opened from a Smartphone using the UrmetSclak APP. The Gear is positioned inside the home and is powered by 2 rechargeable batteries. It can be used with Euro or Oval cylinder locks and does not eliminate the mechanical key. The Gear must be completed with a Euro cylinder lock or with the Euro/Oval cylinder lock adapter.
