Key will not remove when locked.

[john1945]

Greetings,When I lock a multi point door I raise the handle, and turn the key (inside or out) the door locks. However the key cannot be removed. Turn it back door unlocks,key extracts. The mechanism has 2rollers(mushrooms)and two hooks and clearly work,markings are GU and Mark2. I have removed the barrel, what I assume is a locking flap appears on locking. Have tried another key. Clearly can lock the door by leaving inside key in but have to leave house by other exit. Any ideas,thanks John

The "mushrooms" or bolts need adjusting.
As it obviously works when the door is open and you artificially lock it.
