I had lost my keys and have to get to work, so I pulled the ignition out, and went to start with a screwdriver, it turn over but the locked in the on position and lights on dash said secerty system, now the ignition is locked in the on position and car will turn over but not start.

This procedure will bypass the sensor in the ignition switch but the rest of the system has to be operational.

Look for the black wire and the yellow wire from the pass-lock sensor in the column, cut the wires and you can solder in a 2.2 K ohm resistor connecting them together and then attempt to start the car. It will stall do not turn the ignition off. Let the ignition on for ten minutes or until the theft light goes out. Turn the key off for ten seconds then attempt to start the car. If it now runs you have been successful. If it does not you either made a mistake or there are other problems besides the ignition lock cylinder.

Well nothing changed after doing what you said, but I really needed to know why my ignition is stuck on the on position? I could not turn key off like you described, wait ten minutes turn key on off position for ten seconds. Then restart car, could not turn switch off for ten seconds. Because it is stuck in the on position, there for system could not restart like you said. Right now I have battery cable off negative.

There may be a cable connected to the shifter that stops you from locking the steering wheel unless you are in Park.

Find out why it is not unlocking the switch. You have to investigate this yourself. Move the shifter around and see what the cable is doing if anything.

Okay, the cable moves two little buttons in and out as I shift, look at orange, changes nothing.

This system may not work with the lock removed. It is not designed to do that. My advice is repair the damage and put the system back to original condition.

Nobody told you to hook those wires together. You were supposed to solder a very specific resister between them.
