The engine may start and stall with the security light flashing. This is commonly caused by a failed passlock sensor which is part of the ignition lock cylinder. A secondary cause could be the ignition switch itself. Worn contacts inside the ignition switch can cause voltage drop issues which can affect the passlock system. Proper diagnoses should be performed before replacing any parts.

    Same here. Passlock system would engage the security system preventing me from starting the car. After it got so bad it was (especially when cold/wet outside) doing it more often then not and started making me late, I bought a new ignition switch (large number of complaints about this elsewhere online) and got ready to replace it.

    Access it by pulling out the center dash vent (above the stereo) and looking where steering column comes in from the dash. You'll see a module about the size of a small fist attached to the ignition assembly. Since this is far from the only electrical problem these cars have, I decided to try re-socketing the module and making sure the wires were all seated well before replacing the part. AND IT WORKED! I haven't had any issues with it since trying this 6 months ago. Very glad I did.
