PVC Door worn lock

[MARTINI77]

Hi

I cannot lock my pvc back door.

I can lift handle and all locking parts engage. I have checked this with door open.

I lift handle to engage multi locks and then put in key with is at the 6 O Clock position. I turn it anticlockwise. Normally it would go back the the 6 O Clock position where I can then remove the key. This happens whether door is shut or not.

Now it is only going back to the 7 O Clock position not quite making the full 360 degrees of turn. Hence I cannot remove the key to complete the locking process.

I have given it a good squirt of WD40. Didn't know that this was a bad move until I read forum about ten mins ago.

I am hoping that its a quick fix i.e new cylinder and not a full lock and locksmith call out.
Regards

John

If it works while the door is open then its a problem with the adjustment, it may have dropped slightly or just expanded with heat, normally if the key doesnt turn fully round then the handle hasnt quite gone up enough, a dropped door usually causes this.

If you have these type of hinges then an use an allen key (6mm i think)under the hinge pins to lift the door a bit

If its the barrel at fault then theres plenty of recent threads on how to remove barrels, how to measure etc etc and they're quite cheap too, no need for a locksmith

If you cannot remove the key with the door open or closed, then its the cylinder at fault. Sounds like the cam has slipped (its the black section in the middle of the cylinder), preventing the key from doing a full turn.

Replace it - many threads on this subject.

check the movement of the cylinder out of the door too
