found on another site, just keep in mind your vehicle must have a fully charged, good battery because the process takes some time. if you have any doubts put a battery charger on it.

To do the security relearn:

1.) Attempt to start the car by turning the key to the Start/Run Position.

2.) Observe that the vehicle fails to start and that the security light is illuminated.

3.) Release key to the 'ON/Accessory' Position. (DO NOT turn key to the 'OFF' position).

4.) Allow the vehicle to sit with the key in the 'ON/Accessory' Position for at least 10 minutes until the security light turns off. (turn off lights/radio/etc to save battery)

5.) Turn key to 'OFF' position and remove key. Allow the vehicle to remain in the 'OFF' position for at least 45 seconds.

6.) Repeat steps 1-5 for 3 cycles.

7.) On 4th attempt, your car should now start.
