MY CAR WANTS TO TURN OVER BUT WON'T. I BELIEVE MY SECURITY SYSTEM STOPPED IT.

What is your question?

At ONE TIME BEFORE A MECHANIC WORKED ON MY CAR AND CHANGED A FEW SENSORS BUT THE CAR DIDN'T START. HE THEN REMEMBERED THAT THE SECURITY SYSTEM WAS NoT ALLOWING IT TO SPARK, OR LETTING THE GAS FLOW. How do I fix it myself so the car will start? I need to go to the hospital to get help with my back.
