Anti-theft immobilizer preventing car from starting

When I was installing the remote start into my car with push-to-start, something went wrong and I couldn’t complete it. I started undoing everything and tried to start the car. During this process, I guess I forgot connecting one of the wires I cut, which made my car immobilized. I’m trying hard to get it back to start. I tried following the solution mentioned for Hyundai cars on your website, but still unable to start. Can someone please help me get my car started?
