New lock on the door.
The problem was that they came in the morning instead of the afternoon... and I was in kind of a nightdress, so when they rang the door I was super quick to take on a pair of pants and tried my best for the nightdress to look as a longer t-shirt... I got to the door just seconds before they used the main key. 
They had some troubles with my lock, it didn't want to move at first. Hanging on for dear life until there was a miracle spray that melted the resistance away. And here it is, the new door lock.
I'm so very tired today. Haven't got much done, but there's a new day tomorrow.
