Bmw E46 no crank no start

Описание: Need help with my BMW 2002 E46 325CI. I HAD IT WORKING AND RUNNING BEFORE THEN ALL OF A SUDDEN IT JUST DOESN’T START.  It does start sometimes and when it does start, it starts up very clean. Haven’t done a EWS test yet, just replaced battery in key, car battery has 12.6V. Let me know if you have any more questions about it to further help diagnose it. I am in need of help. Thank you!  🙏
