The security door can only be opened with a key. Why can't the handle be opened?
It's a two - hand handle. You can drive with a two - hand handle. But you must use the key when you lock it
The handle can not be opened because the bolt in the handle (the square type long pin) is separated from the lock body, or the bolt is missing, if it is separated from the bolt and inserted into the square hole of the lock body.
You should use the AB lock, you first put the handle of the two screws unloaded, you can see there is a box type plug.
