So he can use a screwdriver to turn the ignition switch and it starts and runs fine? But if he tries to use the key and ignition lock cylinder he loses spark?
I would start by checking to outputs from the actual ignition switch. It may be worn or faulty and using the ignition cylinder itself is not making the connections. Looking at the switch it is possible that using a screwdriver could push in on the connections while the cylinder only rotates and he gets no power to the ignition circuit.
