Don't forget that you can't turn the key unless you've fully turned

the handle with a full thwack against its end stops helps.

Yes I have 2 other doors with similar mechanism and I did do a fair bit
of thumping before I remove the euro lock. With the lock removed I
should have been able to use say an allan key to replicate what the euro
cam would have done but again that is jamming and not turning fully.
