Upvc locks knackered

[Roger465]

Just moved house to one built in 1994 which has 3 external doors of the multi point locking variety. On 2 of the doors, the locks are so stiff I can't lock the doors. Squirted some WD40 into everything, but no difference.

Can the locks be serviced or repaired or replaced or anything?

Thanks

How are the locks if the doors open.

Still not perfect but better...?

Sorry, I should have verified, is it the locks that are difficult to turn, or is it the handle that doesn't turn and engage propely before you turn the locks.

It's the locks. So the key won't turn past a certain point once the door is closed and you pull the handle up.

 

[Doggit]

But if you open the door and then lift the handle, and turn the lock, it's still stiff, but better. That implies the hooks aren't engaging in the frame because the door dropped.

Ok makes sense I guess... can anything be done?

Check on Youtube how to toe and heel a upvc door. You'll need some spacers, and to be able to get the glass out (or get someone to do it for you) but you effectively need to put some spacers under the glass window on one side at the bottom, and the other side at the top, to force it back up. That's assuming that there's glass in it of course.

Thanks mate, that's really helpful. Once I have a basic grasp of the problem, I can take it further. Cheers
