I assume you have already tried a relearn.

You cannot totally eliminate the system. The computer has to receive the unlock signal from the ignition switch or it wont turn the fuel on.

That being said, you can bypass the sensor in the ignition switch but the rest of the system has to be operational.

Look for the orange/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 don't 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.
