I may ask or say some stupid things, I'm trying to dumb the question to my level. When we first got my wife's 2013 EQ, we thought it did not have remote start, because the buttton did not work. I'm assuming your remote does not have the arrow in a circle button.
On her previous truck a Jeep, you pressed the arrow/circle button twice, the horn honked and it cranked. After thinking about it for two weeks, I got online and looked it up, as we did not get an actual owners manual (there were about 4 badly torn pages in the glove compartment). That's when I found out you have to hit the lock button twice, then hit the start button. That was a year ago, my wife still can't get the hang of it, she hits the right buttons it just doesn't work for her. LOL I do it for her in the mornings when the frost is on the window, but she's SOL in the afternoon when it's like 100F.
Anyway back to the original question, does your FOB have the circle button. (again I work on the KISS principle the stupid question is on me not you.)
