Has anyone come across replacement locks for double glazed doors that work similar to the old Yale type. So that when you close the door it locks without having to use the key. and if you dont want it to lock you can put the snip on. It seems strange to me that in these times of increased crime a backward step takes place with these locks that need the key to lock them. In my opinion the old system was better, when you shut the door it meant that a key was required to gain entry unlike now were you only have to push the handle down.
