Can I start my 2018 CX-9 using the auxiliary key only like we used to do with the 1st gen? Sometimes I need to leave the car in a mall parking for example and my wife can find it after and drive home. We used to do that with our 2010 when we go out bringing only 1 key fob, so we split it; one gets the fob and the other gets the auxiliary key, and it always worked. Any way to achieve this with our 2018 model?
