Pontiac Grand Am Forum:security light problem

My 2000 Grand Am does this also. Turn the key to the on position for 10 minutes then turn off, repeat 2 more times. the system should reset. Mine usually resets on the second time, if the security light stops flashing then i try to start. My mechanic told me it takes three times to reset but it never has on my car, good luck.

This is caused by a bad ingnition switch in most cases however if you have a cut key (non factory ingnition key) sometimes it will register it as a bad key..remove the key and try again...however I do believe you only get 3 tries otherwise the car is locked out of startup for 30min to 1hr.
