Everyday Usability 36: Electronic Locks

Lately an electronic lock confused me, but to my rescue I have to say that it managed to confuse a friend of mine as well. The photo below shows the lock. Where would you place your key to open the door?

For me there appeared to be just one option, the metal circle below the handle. Unfortunately nothing happened when the key was pressed against it. Instead it turned out, after several trials, that the plastic structure on top was not only an aesthetic element but also the proper device to open the door. Rethinking the design I remember some electronic doors with a similar plastic device, but in my memory they have a small lamp indicating them as a device. Besides to add a lamp as visual cue it would have been much easier to open the door without the visually dominant metal circle below the handle. A company logo could have been integrated as engraving.
