Security problems with La Gard and S&G electronic locks
http://tresoroeffnung-bayern.de/blog/20 ... hloessern/
And a short summary: There is a tool publicly available in Germany which opens La Gard Safeguard, Basic and 33E locks until about 2014 and S&G 6120 series locks within about 15 minutes just via the keyboard cable.
I assume the weakness was known some years before (since 2014?) to safe technicians which kept quiet. And I assume the tool is not only available in Germany. This tools looks to me like what he is talking about: http://www.taylortechtools.com/phoenix (came up after a very very simple search as the first hit). So if you have such a lock you might want to consider a replacement.
