so how do i get the code do turn ignition key on and off
Youll need to go to Autozone and have them check it or get your own OBDII code reader. I got one from Harbor Freight pretty cheap.
Vehicles older than 1995 models typically feature the OBD-1 trouble- code system; cars made after 1995 usually have the OBD-2 system. The differences between the two systems are that the older codes contain two digits, while the new codes begin with a letter indicating what system in the engine is malfunctioning, followed by a series of numbers (see Resources). The key "On/Off" method works on older vehicles; the digital dash and jumper-wire methods work for newer vehicles.
