I got it, thanks for everybody's help! I was on my "giving up after this attempt" attempt and I really "put some back into it" and it turned free! I've tried it a number of times since and it works but still seems to be touchy. If I gently put pressure on the key and then back off and do it again, it seems to work. Do I need a new key? MAybe they teeth are worn a little? Regardless, I'm back on the road.
