You might have longer lasting results with the "30 minute" security re-learn procedure. Or you have a problem with one of the Passlock components.
Here's the Security Relearn Procedure:
(Copied and Pasted from a past thread generously provided by member RickCoMatic)
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, DO NOT remove the key.)
4. Allow the vehicle to sit with the key in the 'ON/Accessory' Position for no less than 11 minutes (the security light should stop flashing, if not wait up to 3 more minutes).
5. Turn key to off position and allow the vehicle to remain in the 'OFF' position for no less than 30 seconds.
6. Repeat #1 - #5 for 3 cycles.
7. On 4th-5th attempt, car should start.
NOTE : Since this is a fairly long procedure, I would limit all electrical sources, such as disconnecting headlights, to prevent discharge of battery.
NOTE 2 : It is SAFE to wait LONGER than the allotted time, but it is not safe to wait less time. I.e. 12 minutes instead of 11 minutes should be safe; however, waiting 10 minutes instead of 11 minutes is not safe.
Properly executed, this procedure should take approximately 35 minutes to complete.
