New French door won't lock

[kingandy2nd]

Hi all,

I've recently fitted some upvc french doors I got from screwfix. Unfortunately I can't get them to lock - more specifically I can't turn the key in the lock sufficiently to get the centre bolt to move into a locked position. It won't even do it when the door is open.

The key moves a little in the lock, and the bolt moves a tiny bit but no more. The lock cylinder works fine when removed from the door.

I guessed that the mechanism was buggered because it was only a cheap door, but on buying another identical mechanism from eBay I'm still having the same problems.

Any tips for me as to what I'm doing wrong? Thanks

Hope you don't think I am being funny but if it has a turning handle are you pushing it up far enough?

Fair question mate. Raising the handle as far as possible makes no difference.

On my other patio door you don't even need to raise the handle to lock the bolt, it just moves on the turn of the key.

Don't know if it is any help as I don't know if your's are sliding or French but my old sliding patio had a pin that had to be pressed in, if you tried it when the door was open you had to push it in by hand.

Sorry should have been clear, these are upvc french doors. Nothing else except handle and lock on show.

Sorry no other ideas unless the euro lock is faulty or binding on something.

Well I've just pulled the mechanism out of the door again. Out of the door it still won't lock - the bolt moves slightly upwards as you turn the key, but doesn't move horizontally.

Could I have been unlucky twice with two faulty ones?

Hard to say without having a go in person but I would think it quite unlikely to have 2 duff lock mech's.

Id take the lock into a screwfix branch and get them to try it.

As its French doors is there a euro cylinder in the slave door you could try in the master door?

Victory!!!

In looking again, this particular mechanism does need for the handle to be lifted up fully to lock. However the bars (don't know technical name) which come from the handle and pull/push the top and bottom locking mechanisms were not aligned in such a way that it allowed for the bottom bar to let the lock mechanism work.

By shifting these bars downwards a cm and then re screwing the gear mechanism back to the rest of the lock mechanism it has works
