During particularly cold or particularly hot months your upvc door may have contracted or expanded slightly causing it to not close properly.
Door lubrication is required.
If your upvc door won t lock even when still open this is usually because of the following reasons.
Pry up on it until it comes loose and remove it.
There could be something stuck such as part of a door mat at the bottom edge of the door stopping it from closing.
Try wd 40 on it first.
Multipoint lock is damaged.
Problem with lock cylinder.
Upvc gearbox failure most common.
I ve put wd40 and 3 in 1 in there no.
If it won t lock open the door.
Tap the end of a chisel under the door stop on the striker side of the jamb.
From the outside i can see what appears to be a brass pin but it s stuck and won t move no matter what.
Upvc gearbox failure or multipoint lock damage.
The door probably will need adjusting.
What happens is that the locking points and keeps misalign making the door harder to open and close.
Basically when it gets a bit warmer or colder than normal outside the door starts to shrink contract and then expand.
You lift the handle up to engage the bolts and the key goes in and turns perfectly smoothly.
You say something has broken off from the locking mechanism it could have broken off from the gearbox this is in the centre of the locking strip.
But if this happens with more than one key its the lock if another key works ok look at both keys if the one that works is smaller in anyway file the bad key to make it the same size sometimes if you move the key in or out slightly you can often find a way of making them work.
All of these factors can make locking and opening your upvc door difficult.
Once you ve checked the door and frame make sure you have a look underneath the door.
You say there is an obstruction when you turn the cam i think the gearbox is at fault.
