3 point door locking system jammed Post your questions and get answers concerning many areas of this subject

[ajjbultd]

hoping someone can advise me, I have a 3 point locking mechanism on my main (aluminium) door (where you have to lift the handle to actuate before locking) but due to some reason (I suspect someone slamming the door) the handle only lifts part of the way meaning the 3 point system only comes out halfway and I am unable to lock the door!!
can anyone suggest what may be the problem and if I would be able to fix?

With the door open are you able to move the handle all the way up?
If so the problem will be with the latches not fitting into keeps and that most likely means the door has dropped. If the handle doesn't go all the way up when the door is open, it sounds like the mechanism so try WD40 or something. But most likely you may have to replace the mechanism
