Key will not turn inside cylinder
!!! UPDATE: We have bought some graphite and covered the key and sprayed some inside as well. It unlocked it! Did the job. Will get it replaced soon though. Thank everyone for the suggestions!!!
I’ll try to explain it as simply and clearly as I can.
Our balcony has a door, which is a sliding door with a handle installed on the glass.
When we insert the key it goes all the way in without any trouble, but for the last week it has started to not want to turn right or left.
Today it’s completely stuck in the neutral position, in the middle. It will not turn left (to unlock the door) and it will not turn right (to lock it). But right now in the neutral position the door is still locked.
We have tried pushing, pulling, lifting, shimming the door and keyhole, the cylinder. Inserting the key slowly by 1mm each time etc etc.
It just won’t budge to the left. Here is a photo of the handle we have installed.
What could be the issue and the solution? Thank you
