What you need is a extra key hoop. They are about $20 at the dealer. Remove the key halo plug for the ignition key and plug in the spare halo and put in your ash tray. Then put the 98 key in the ashtray and start the car with the 96 key.
You are using the 98 Key chip for EWS verification and using the 96 key for the ignition tumblers to start the car.
