I have a problem locking this door.The multi point latches appear to be working ok but when I come to lock it the key turns half way and then meets resistance. The handle has to be turned up as hard as possible and the key will then complete its turn with difficulty. The same happens when unlocking. This problem also occurs if I attempt to lock it when the door is open so it cant be caused by the keeps not being in alignment.
Ive also tried a different eurocylinder and there is no improvement.
Help please.
