First, I would get her softer and more supple so she turns better with direct reining. Teaching her to neck rein isn't going to help with her steering problem. It will add more confusion to her. Start with flexing her on the ground and flexing from side to side undersaddle. Also, do a lot of circles and serpentines when riding.
To teach her to neck rein, bring one rein against the side of her neck and leave it there. When she doesn't respond, and she won't, use the other rein as direct rein. That's why she needs to be better at direct reining. With lots of practice, she will learn that when she feels the rein against her neck, you want her to turn.
Everyone should be allowed at least one bad habit, and that's NOT owning a horse! Mares RULE! Geldings drool!
