i wonder if one could really copy more advanced keys (f.e. the ones from KABA [0] are pretty common here) by just having some scans of the keys. these keys generally have different layouts on each side, and sometimes also on the small top/bottom sides. so just a snapped photo definitely would not be sufficient. and even with flatbed scanners like the team in the article used, capturing the depth of the holes might be problematic...
