It would help if we knew the year, make and model of your car.

in order of what you should look for, clean the contacts on the key, try different key, try bypassing key with resistor, try bypassing security module signal to pcm.

It'* probably not actually the ignition switch unless he actually checked it out. The VATS wires have a tendency to break and or fray with movement of the steering wheel. A common point of failure is where the wires connect to the ignition switch, which is why the dealers usually just replace the switch instead of trying to repair the wires right by the switch
