I do also have an expired card, but sought for Schengen visa to avoid these kind of issues and whenever possible I would suggest getting a Schengen visa when the cards expire - though I am aware that this is not as easy as it is written.
In the meanwhile, I would also print out the decree that spells out the extension - in theory with that decree even the expired cards should be valid - but it is all in theory.
I’ve previously written here that Turkish airlines let people get on planes with SEF appointments, but of course, that was just one reflection from the Istanbul airport. Expired cards can always become a headache especially with an officer who is unwilling to listen to you or spend time understanding the issue.
