This should work to reset the security system.
30 Minute Learn Procedure
Turn ON the ignition, with the engine OFF. Attempt to start the engine, then release the key to ON; the vehicle will not start. Observe the SECURITY telltale; after approximately 10 minutes the telltale will turn OFF.
Turn OFF the ignition, and wait 5 seconds. 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 and/or passwords on the next ignition switch transition from OFF to CRANK.
I have had good luck with disconnecting the battery for 30 minutes and then reconnecting it, unlock the drivers door with the key or use the remote and it should be reset.
