Some time ago Bobik has answered a question about lockpicking:
Bobik wrote:...that will just force everyone to store their belongings in a safe place and there will be nothing much to pick. Also we would like to reduce to minimum amount of PvP, where one of the sides of that PvP is not online and can not counter you in any way. That statement goes both to lockpicking and to PvA (player vs assests) destruction and so on. We will do our best to avoid that senseless gameplay moments.
Also you probably know that you cant pick door locks, which means that if people will store their items in the chest which is located in the house itself, there is no use to have lockpicking. But I believe what Bobik has written covers the topic pretty much.
