    this is a dealer repair, if u do it u will be unable to start the car and will end up taking it to the dealer for re-programing of the module to accept the new key.

You need to get rid of passlock or spend a lot of money in the new cylinder and key that only a dealer would make. There is a detailed write-up for bypassing passlock here: http://newrockies.ca . The guy is great, and this was the only way I was able to save my Park Avenue.

What will cause a 1999 Pontiac Sunfire to not go into the extended learn mode when replacing the ign lock assembly .


Did you clear codes ? . All codes in the theft deterrent module must be cleared for a relearn.
PASSLOCK Changing - Components Description
Important: Due to component variability, the vehicle theft deterrent (VTD) system must have the learn procedure performed regardless, if the vehicle starts on the first ignition cycle after a VTD repair.
All codes in the theft deterrent module must be cleared for a relearn.
Engineers design the Passlock™ system in order to prevent theft even if the various theft deterrent parts change. The Tamper mode will engage if any of the following components change:
• The Passlock™ lock cylinder
• The instrument cluster
• The powertrain control module (PCM)
If you replace any of the above components, the system will enter the long tamper mode. If the system enters the long tamper mode, ensure that the system completes a long tamper mode cycle. During the long tamper mode cycle, the THEFT indicator will flash for the full 10 minutes. The instrument cluster and the PCM require the full 10 minutes in order to complete the learn cycle. Ensure that the ignition switch remains in RUN until the indicator stops flashing. If you turn the ignition switch before the indicator stops flashing, repeat the long tamper cycle from the beginning.
Are there any codes ?
Problem
Action
The THEFT SYSTEM indicator will not light under any circumstances.

I installed a new steering column in my 2004 Pontiac sunfire and now it will not start. It tries then I beta back fire.


Anti-theft system isn't allowing it too .
The Passlock™ System is provided in order to prevent vehicle theft if the ignition lock cylinder is forced to rotate or the ignition switch is operated while separated from the ignition lock cylinder case. If starting is attempted without authorization from the Passlock™ System, the powertrain control module (PCM) will disable engine starting. Start disable may be in the form of fuel disable or starter disable, depending on engine application.
The components of the Passlock™ System are as follows:
• The ignition lock cylinder and key
• The ignition lock cylinder case, including the Passlock™ sensor
• The ignition switch
• The body control module (BCM)
• The security indicator on the instrument cluster
• The powertrain control module (PCM)

Car starts then cuts out


MAKE SURE YOUR BATTERY IS CHARGED OR NEW. TAKE OFF THE STEERING COLUMN COVERS. PUT THE KEY IN, NO EXTRA KEYS HANGING FROM IT. START THE CAR. UNPLUG THE CONNECTOR WITH THE YELLOW, BLACK, AND WHITE WIRES CONNECTING TO THE PASSLOCK/LOCK CYLINDER, AND IT WILL CONTINUE TO RUN.TAPE THE CONNECTORS. REPLACE COVER. YOUR THEFT LIGHT WILL STAY ON/FLICKER. YOU HAVE DISABLED THE SYSTEM. NOW THE CAR WON'T CUT OFF WHILE TRYING TO START IT. SUMMARY: YOUR PASSLOCK WAS FAILING. OTHERWISE IF YOUR IGNITION SWITCH WAS FAILING, IT PROBABLY WOULDN'T TRY TO START. FOUND THIS ON A SITE FOR A CAVALIER...... AND SUNFIRES DIAGRAMS AND THEFT FEATURES ARE MOSTLY THE SAME. NO PELLET IN KEY. NO RESISTORS. NO CUTTING WIRES. NO 10 MIN RELEARN. HOPE THIS HELP.

Is it possible just to remove the vtd on a 1998 pontiac sunfire and how can I find out if it does have the vtd on this 1998 pontiac sunfire ...car is not starting ...ruled out everything else ! Any help...


Is the security light lit on the instrument cluster ? The vehicle has spark ? Does it have fuel pressure ? Did you check with a fuel pressure gauge ? The passlock anti-theft system use's a sensor in the ignition lock assembly .
The Passlock™ lock cylinder is a locking cylinder that turns a rotating magnet past a stationary hall effect sensor. The rotating magnet creates a resistance code (R-Code) that the cylinder sends to the instrument cluster. The Passlock™ lock cylinder interfaces with the instrument cluster through a 3 wire connection. The 3 wires have the following functions:
Plus software programmed into the instrument cluster and PCM/ECM engine computer .
There is nothing you can do if the anti-theft system is not working , taking out parts won't do any thing , the software in the computers still won't let it start . Your best bet ,take it to a GM dealer .

My 1999 sunfire gt starts and runs for a second then dies what can i do to fix this problem??


GM vehicles like your sunfire are notorious for failing antitheft systems called passlock. When this system fails, you get what you have. The engine will start for 5 seconds or less and then stall and shut down. There is a dead giveaway for this problem, after it stalls you'll see a light on the dash that says SECURITY or ANTITHEFT. If you see this light, that explains your problem. Here is a link that will help you.

I have a question about my 1999 Pontiac Sunfire. I have a key, that has a hole,with a black center. is that black center for the anti theft system?? and if that key is not used, will that cause problems?...


there is nothing special about your keys , no transponder . Has a hall effect sensor that is part of the ignition lock cylinder housing . You could get a key made at hardware store . woludn't make a difference .
