The security light is on my 2001 buick regal LS wont start how do I fix this?

I have a 2001 buick regal LS. I recently had to change the steering column out and now the care will not start. I am thinking its because the security light is on. Does anyone know how to reset the code to make the security light go off so the car will start? Or if maybe it could be something else?|||Try this to reset the pass-lock security system.





This is free and all it takes is about 35 minutes of your time. If it doesn't work, all you are out is a little bit of your time.





First. make sure the battery is fully charged. If you have automatic headlights or daytime running lights disable them and it will help save your battery power. You should find instructions for this in your owner's manual. You could park the car in the sunlight which would not activate your head lights on most models.





Turn off all of the vehicle accessories. Roll down the windows. You roll down the windows just in case your doors lock while resetting your pass-lock security system.





Place the key in the ignition. Turn the key to the run position but don't start the engine. Don't use the accessories position as this will not work.





Leave the ignition in the on position for 10 minutes. At the 10 minute mark the security light will flash.





When the security light flashes turn the ignition off.





Wait a minute





Repeat these steps two more times. Do not start the engine or place the ignition in the accessories position or you will need to start over from the beginning.





After the third time of doing this your security system should be reset.





You say you changed the steering column. If this procedure does not work you may need to take the car to your nearest GM service department and get that "Great GM Feeling". If you did not install the original ignition switch with the new steering column it is very possible that the new ignition switch needs to be matched with the Pass Lock security system. This can only be done by a GM dealer because this process requires the use of a special scan tool connected to the diagnostic port. Most likely the only person that you will find with this scan tool is a GM dealer.





And no, the Pass Lock 2 security system can not be disabled. It is integrated into the car's computer systems and can not be bypassed or disabled.
