That is why I said go to a place that installs theft systems just ask them I didn't say to have them diagnose it. If you have a manual It should be in that as well but I kind of figured you didn't

This uses a Passkey security system and the most common failure is the sensor in the ignition switch. There is no reset procedure for this one. You can bypass the sensor if that is the only problem but the rest of the system has to be operational.

That sensor can be bypassed. You would need a digital ohmeter to measure the resistance of the pellet in the key. Now go to Radio Shack and buy a resister of the exact same value as the key pellet. Go to the base of the steering column and locate the two thin white wires that go up to the sensor. Cut the two wires and solder the resister between the two ends coming from the harness. This will permanently bypass the sensor but not the rest of the system.
