the anti theft chip came out of my key now my car will not start

my dad had just bolted in my battery and cleaned the red wire and tighten it. we took my car down the road and did not have any issues. we pulled back into the yard and parked the car. the car was still running at this point. my key to the car has been busted open and we was wondering what the white thing in it was so while the car was still cranked and running we pulled the white piece out. the car made a funny noise instantly as soon as we took the white piece out. so we quickly put it back in. then we cut the car off. well we tried to recrank it and it would not start. the lights would pop up but the engine would not start. i am not to car savvy so i am not sure the technical terms to use. but i had a spare key and we tried using it, but the car still would not crank.
