INSTALLATION
Since my office/lab doesn't have exterior direct access from the street the door to my office/lab is nothing exciting, it's basically a 20 year old wooden door.
For this door the proper mount is B (over 3mm overhang) and as you may be able to tell it attaches onto the door via a double side tape.
After that i only needed to place the key in the lock and mount the Nuki Smart Lock 2.0.
You may also want to mount the tiny door sensor so you may know at all times whether the door has been opened or not (again this uses a double side tape).
The keypad was mounted on the exterior of the door as seen above (close up cause the exterior of the door had quite a few scratches on it).
