It may be the wrong key, or it may be the wire for keysense broke in the column, but it sounds like an ignition/key problem, Do all lights and radio work? Or is the car dead? And have you checked the cable going to the starter?
Some dont even have the chip. It can be the starer solenoid at the starter on GM. For an "engine not cranking" condition with A/T, determine if condition exists in both Park and Neutral positions. If condition occurs in one position and not other, a more probable cause is neutral start switch.
