Yes, tighten the feelers up tight, put in the lock, press in, then rotate a bit from side to side and the feelers should set
The other way is to have the feelers slack and tension the lock, slowly push each feeler in until you feel the shear line, do that on each one and you should get it to turn, remove the tool and tighten the feelers up.
I dont think the ace series can be called high security,
