Please help me with my Fit

Hey all...I have a 2015 Fit that suddenly stopped cranking and yes I'm aware of the push start issue. I bought a new OEM button and had a mechanic friend put it in and still nothing. So it's now at a different mechanic's and he's struggling too. The smart entry system light had been coming on and off a bit but it was cranking just fine and then suddenly nothing. The original mechanic cleared all the codes after replacing the button and no new codes are coming up, but still no crank.
