Answers :

This car must have a chip in the key, if you look at the key you will see a chip, you will need an ohm meter, this chip is a resistor, you can take it to radio shack and ask them to measure the ohms and give you a resistor with the same ohms, you will take that resistor and install it in the wire and this will bypass the antitheft system, you will need to look under the dash follow the steering column down from steering wheel and you will see an orange wire, you will cut that wire and inside of it will be two small wires, when you cut it you will use the part that goes away from column not the part going up to wheel, strip orange coating back a bit and you will have two wires, what you want to do is connect wires together using the resistor, in other words the resistor will connect the two, one wire goes on one end of resistor and the other wire on the other end, you dont need to soilder them just twist tight and tape, the system is now bypassed, good day.
Replace the ign lock cylinder. Or get new cylinder and plug it into the connector from the old lock cylinder at the lower part of steering column. Put old chip key in the new cylinder and hide under dash. Start car with a duplicate key from old key. No need to tear apart steering column ever again for this problem.
