Over the passed Two years I have had to replace 3 cylinders in my front UPVC door. syptoms are that we are unable to remove the door key, when the door is unlocked. What is causing the problem?

Ok so its not some cheap no name brand. The things I can think of that can make the cam slip is if the incorrect key blank (if you got more keys cut) have been used which can do this. If there’s a key on the other side of the cylinder. Or I think this can happen is the pin in the centre of the cylinder wears so does not properly engage the cam.
Not sure if a stiff locking mechanism can cause the cylinders cam to slip.
Can you remember at what position was the black bit (the cam) was at on the old cylinder? With no key was it at 5 o’clock or 7 o’clock or 2 o’clock or 10 o’clock position?

I have no idea. present cam is positioned approx 3 o'clock when in the unlocked position
It's well out of position then - should be at 5 or 7 o'clock, depending on orientation of the cylinder. I've encountered this on most brands, so it's not unique to cheapo's. The most common cause is trying the open the cylinder whilst a key is in the other side.
