Aim at the center mirror, push the button and keep holding and aiming. I find it's not usually instantaneous and requires some aim. Infrared = fail.

The receiver is in the clown nose on the mirror. you need to be fairly direct in aim & close to the car. As far as the key - you have the earlier key - the round button is lock, the rectangular is unlock. N.B. As remote batteries lose their strength - the reception/range becomes even more crap.
