IT HAS SOMETHING TO DO WITH THE IGNITION NOT KNOWING IF THE RIGHT KEY IS BEING USED. IT MAKES ITSELF THINK IT HAS BEEN STOLEN SO YOU HAVE TO HAVE THE DEALER REFLASH YOU SECURITY SYSTEM.
ALL I KNOW TO TRY IS TO WAIT 3 MINTUES AFTER TRYING TO START IT, AND FASTEN YOUR SEATBELT THEN TRY TO START. IT HAS SOMETHING TO DO WITH THE PASSKEY ll SECURITY SYSTEM. I HAVE HEARD THAT WHEN THIS HAPPENS IT MAY BE A FUSE GOING BAD BUT IT ALSO MAY NEED TO BE "RE-LEARNED". SO IT MAY NEED TO GO TO DEALER

Could be the key itself, the lock cylinder, or the Theft Deterrent Module that controls the whole system. This link explains the system and offers a very good way to just bypass the system permanently...

I had my ignition cylinder & housing replaced now my car won't start. How do I reset the passlock system so my car will start


Hello, Try this: Get in car, turn the key to start, when it don't start let key come back to run (do not turn off) The security light should be blinking, let car set for about ten minutes or until security light stays on steady at that time turn key off for 10 seconds then turn back on (do not go to start) security light will be blinking again wait 10 minutes and security light should go out. Turn key off, wait 10 seconds . Turn key on (do not go to start) security light will be blinking again, wait 10 minuets and security light will go out. AT THIS TIME TURN KEY OFF FOR 10 SECONDS THEN START THE CAR.

The locks jump up and down when i drive,sometimes wont start


the security system problems are common on this - do the lights flash and horn cycles when it locks up - the security system is wired into car main computer - can't be bypassed as far as i know - i read that to get around this lock doors manually - no key or remote - also hood switch could be problem

Car having troble starting


ok whenever the security light comes on its a bad thing. it means that for some reason your cars passlock system is not recognizing your key. unless you have a buddy with a scan tool (not a code reader, used for changing computer settings) you will probably need to go to your dealership and have them check your passlock system. they may be able to reset it to match your key again or they may find that your passlock mechanism in your ignition is bad.

Starts but then it shuts off


Make sure those 3 wires on the passlock sensor are good.That sensor is on the lock cylinder on the right side of the steering column. You may want to check the wires on the ignition switch also.(green,black).But I would look at the sensor 1st since that is where they hook up those remote starters as far as I know.

Security light flashes car wont start


You need to go to GM and find out what defective part is causing this, the most common is the sensor in the ignition lock cylinder fails, then when you try to start it doesn't send a usable signal from the key chip to the electronic module that controls the security system and it locks you out.
