I found this

This may work: 1. Turn on the ignition, with the engine OFF. 2. Attempt to start the engine, then release the key to ON (vehicle will not start). look at 'security light', after approximately 10 minutes it should shut off 4. Turn off the ignition, and wait 5 seconds. 5. Repeat steps 1 through 4 two more times for a total of 3 cycles/30 minutes/ The vehicle is now ready to relearn the Passlock Sensor Data Code The vehicle learns the Passlock Sensor Data Code and/or password on the next ignition switch transition from OFF to CRANK. You must turn the ignition OFF before attempting to start the vehicle. 6.Start the engine (the vehicle has now learned the Passlock Sensor Data Code and/or password).

Not sure though as I would think some of the body sensors are missing and not giving the anti-theft computer thing a signal.
