Sometimes when I was working on a mortise cylinder on the Adams Rite latches, I notice it will act as though they were stripped when I tried to remove them. I discovered that the real problem was the wrong backset being used for the lock, and when I tighten the retainer screws, it forced the cylinders against the back edge of the prep, making them slightly impossible to remove.
If you get into this problem as a locksmith technician, all you have to do is loosen the retaining screws on the lock itself and remove the cylinders with ease. I have found that the best way is to use an uncut key blank as a turning tool to turn the mortise cylinders. Once you've loosened the setscrew, simply insert the uncut blank and turn the cylinder.
It’s much better than trying to grip the edge of the cylinder with the fingers and it doesn't damage the scalp of the cylinder like Vise-Grips would usually do. If the blank key won't turn the cylinder: then I would try loosening the retaining screws as I mentioned before.
