This car has been driving me nutts for atleast a year. Its my sister's car sometimes it wont start I tell her to move the shifter down to drive and back to park. Sometimes it starts sometimes it wont. Then after sitting for about an hour it will start. I was thinking of just changing the switch so I figured it was on top of the trans where the shift cable connects but its not. Now she just told me that sometimes the secruity light will flash a few times the day before it acts up. Shit im thinking maybe a bad key. Anyone ever run into a problem like this.

very rarely, I ever had to replace the N.S.S switch.
99.99% of the time is the passlock sensor / anti-theft sensor.
FYI...it is not the key...
replace the passlock sensor / anti-theft sensor, your problem will go away....trust me on that....I've done that passlock thingy almost every week.
Where is it located. Will it have to be programmedvery rarely, I ever had to replace the N.S.S switch.

IIRC, it is in the ignition lock cylinder, as long as the key doesn't have a black resister in it
programming is easy, key on for 10 minutes, then off, and repeat 2 more times
I agree 100%..Seen it a gazillion times.very rarely, I ever had to replace the N.S.S switch.

The large part of the key the part you hold is black. with a BowtieIIRC, it is in the ignition lock cylinder, as long as the key doesn't have a black resister in it

They're located inside the igntion lock cylinder.Where is it located. Will it have to be programmed
You need a passlock sensor which is part of the ignition lock cylinder. If you go to a dealer and get a lock cylinder you can use your old actual cylinder part and just replace the sensor, that is in the part where the cylinder turns, so you dont have to recode the cylinder. Then the theft deterrent must be relearned.
In order to initiate the relearn:
1. Hook up your scan tool to erase any of the passlock/vehicle theft deterrent trouble codes. If there are any other codes, note them before you erase them, so you may address them after the relearn has been completed. If you don't have scan tool then disconnect the battery for 10 minutes before relearn.
2. With the ignition key in the “On” position from the code-clearing step, attempt to start the vehicle. At this point, if the vehicle starts, and the security light has not illuminated, a relearn is not necessary, and you’re done. If the vehicle starts and stalls, leave the key in the “Run” position and wait for the “Security” light to turn off. This will take approximately 10 minutes. At any time during this relearn, the light may flash or be on steady. If the ignition switch is turned off at any time during this relearn cycle that the security light is illuminated, the entire cycle must be restarted from the beginning. For most cars, one cycle will be sufficient for the relearn. If the vehicle will not start after the first cycle, then continue the process from step #3 to the end. Most trucks will require that you continue from step #3 to the end.
3. When the light turns off, turn the ignition switch to the “Off” position for approximately ten seconds.
4. Next, repeat steps 2 and 3 two more times for a total of three cycles. After the third time, the new code will be relearned on the next start attempt when the ignition switch is rotated from the “Off” position.
5. From the “Off” position, start the vehicle, observing the security light. If the vehicle starts and runs normally, and the security light is off, the relearn is complete. If the vehicle does not start, check for trouble codes before proceeding further."
The lock cylinder and transponder will resolve this issue. If you turn the ignition switch to the on position for ten minutes the security system will complete a relearn. This will be your for step for the diagnosis. When the system completes the relearn the security light will turn off. Turn off the ignition and then start the vehicle. The best repair procedure is to let your local GM dealer code your lock cylinder to the VIN. Ensure to discard any remaining keys. I have new keys cut to ensure the old keys don't damage your new lock cylinder. This procedure of discarding your old keys is overkill but will cause you less heartache later. Leave me a PM if you like.
