2002 civic start no start

Question type: General

Bought a 2002 civic about a year ago and from time to time it would crank but not  start , after waiting some time it would fire right up , It's my sons car , he has a key and I have a key , both came with the car , come to find out today that his key works and mine does not , they both turn the lock cylinder and turn the starter but only his will make it run . From my understanding the lock switch shouldn't care what key it is or if it's a screw driver as long as the circuit is lit up , So what's up with that ?.

the key needs to have a chip/transponder in it that the ECM recognizes for it to start , one key given to me by the previous owner did not have one , while it turned the engine over it was not recognized by the computer .
