We don't pay a maintenance fee, owners are responsible for the communal areas. The only thing we pay is for stair cleaning but that's because an owner could be bothered to set this up. If there are any issues we get in the relevant trademan. This is scotland by the way perhaps things are different in England in flats.
Its a bit informal from what I have experienced. We as owners have to arrange all communal repairs and you can follow a Tenement Management Scheme but its basically a set of guidelines on how to maintain shared/areas. But essentially its for us to spot issues and then someone contacts the rest of the owners to try and take action on it.Re neighbours - I'd be getting on the front foot and letting them know beforehand. That way hopefully they'll be appreciative, or what have you.
I have managed to get a simple cabinet key (circular with one groove at the top). Looking on youtube it seems I may be able to use this to turn the mechanism along with a thin metal rod to release the tensioned pins in sequence. But I will get on a ladder and make sure the door isn't just pushed too or the key isn't on top of the box!I have been told, that if you dismantle a green Pentel Rollor ball pen, the barrel of the pen is the correct diameter to fit the circle and one pushed in can be used to turn the lock.
