Not sure if this was discussed but just saw a youtube video that shows how to fit a Mercedes push button on the Q30 to get keyless start button, as simple as that.
Search for "Convert Infiniti Q30 or QX30 to Push Button Start" video on youtube.
The part can be bought on ebay or amazon, costs ~35$. Has anyone actually tried it?
If I remember correctly there was some sort of issue with it where the vehicle didn't have to be in park or something to turn off. Like you could leave it in Drive and press the button and it would turn itself off without issue?
5 out of 5 stars Best $35 Investment for a 2017 Infiniti QX30!!, December 13, 2016
This review is from: Genuine Mercedes-Benz Keyless Go Ignition Button
I am so excited that for a mere $35, this button converted the key-based ignition switch to keyless in my 2017 Infiniti QX30. It took 2 seconds to "install" and worked immediately. Now I can leave my keys in my computer bag and I don't have to fumble with keys at all to enter the vehicle and start it up. Best $35 I could have spent.
