Not starting after battery replacement

Hello, I had recently returned from vacation and my car was not starting off of a jump. I have rep[laced the battery, but I am still having issues starting the car. My vehicle is a push to start. After the battery replacement, the ignition light will turn on but no other lights will come on in the car including the dash. I also believe my key has de-configured from the car. I have replaced the battery in my key as well. I'm not sure If there is something I can do to fix it. Let me know.
