I have a Suedesign front door with a Fuhr motor lock and a Fuhr fingerprint scanner. Also remote controls, which came with the lock. The fingerprint scanner is located in the door, as is the control unit. It works very reliably, even with my damaged hands. My husband is let in by the door less often, but he also has very damaged hands with scars, calluses, and thick hard skin – from work. Therefore, he uses the remote control.
