QuestionQUESTION: Someone broke into my aztek and after tearing off the shroud aroung the steering wheel, cut the 5 wires going to the passkey collar that goes over the ignition cylinder. I don't know that my terms are correct, but hopefully you get the picture. I soldered the wires back together, but it still won't recognise the key. I can start it with the aftermarket remote start, but since it doesn't know when I put the key in the ignition, the second I try to put it into gear it cuts off. I know the resistance has to be right for it to work, but I don't know how to get the right measurement for the key, or which wire the resistance is in. Please help.
ANSWER: Hi Alex:
I assume you put the wires back together on the right wires meaning you matched the colors back up right. There is really no way to correctly bypass that system the remote starter is a cheap attempt to do so. What may have happened is when the column was damaged is the wires may have been pulled out of the circuit board in the passkey module. or the module in the exciter module is damaged. or you increased the resiatnce in the circuits with the repair all of theses are possibilities... The only right way to fix it is to replace the passkey module around the lock cylinder.. Then that module need to be programmed to the car witch is a long drawn out process with out the proper equipment. Us at the dealer use a scan tool and it takes 10 minutes to get the module learned to the truck. good luck :)

QUESTION: Thank you for your quick reply. All the "advice" I had found was on how to bypass a working system, and nothing on repairing a damaged system, as I do want it fixed correctly. A couple more questions if I may. Since I am on a fixed income, and have way more time than money, how do I know the new module I get will match my key? If I give the dealer the VIN or the numbers off the module it has now, will that tell them which one to oreder? Also, once I get it, how do I program the module to the truck? Thank you,
Alex
Answeryou don not have to worry about the key and the VIN. the new module will learn the electronic serial # of each key when you do the learn I have attached to this answer. You will have to do the 30 minute learn process but make sure the battery doesn't go dead turn off all the accories in the truck and if you have one attach a trickle charger to the battery while you do this just as long as the battery doesn't go dead.
Here it is The 10 minute procedure is fo us at the dealer when we have a scan tool to use so jump down past that at start at the 30 minute procedure
:
Set Up a New Theft Deterrent Control Module
Use this procedure only if replacing the theft deterrent control module with an GM SPO Replacement Part.
•Connect a scan tool to the vehicle.
•Turn ON the ignition, with the engine OFF.
•With a scan tool, select Setup New VTD Module in the Vehicle Theft Deterrent, Special Functions data list.
•Follow the scan tool on-screen instructions.
Important:
• When replacing a theft deterrent control module with an GM SPO Replacement Part, the module will learn the keys immediately. The existing powertrain control module (PCM) must learn the new fuel continue password when you replace the theft deterrent control module.
• When replacing a PCM with a GM SPO Replacement Part, the new PCM will learn the incoming fuel continue password immediately after programming and upon receipt of a password message. Once a password message is received and a password is learned, perform the learn procedure to change this password again. A PCM which had been installed in another vehicle will have learned the fuel continue password of the other vehicle's theft deterrent control module. Perform either the 10-minute relearn procedure or the 30-minute relearn procedure after programming to learn the fuel continue password of the current vehicle's theft deterrent control modules.
• When performing either relearn procedure, all previously learned keys will be erased from the theft deterrent control module's memory.
• Additional keys may be learned immediately after the first relearn procedure by inserting the additional key and turning the ignition to RUN within 10 seconds of removing the previously learned key.
• Use only a master key when performing the first relearn procedure. If you use a valet key first, the theft deterrent control module will not allow additional keys to be learned.
Tools Required
• Scan tool
• Techline Terminal with current Service Programing System (SPS) software
10-Minute Relearn Procedure
Use this procedure after replacing the following components:
• The passkey III (PK3) keys
• The theft deterrent control module
• The PCM, see Important above
Important: If replacing a theft deterrent control module with a GM SPO Replacement Part, perform the procedure to setup a new theft deterrent control module prior to the 10-minute relearn procedure.
•Connect a scan tool to the vehicle.
•Turn ON the ignition, with the engine OFF.
•Insure that all power consuming devices are turned OFF on the vehicle.
•With a scan tool, select Request Info. under Service Programming System and follow the scan tool on-screen instructions.
•Disconnect the scan tool from the vehicle and connect the scan tool to a Techline Terminal with the current Service Programming System (SPS) software.
•On the Techline Terminal, select Service Programming System and follow the Techline Terminal on-screen instructions.
•Disconnect the scan tool from the Techline Terminal and re-connect the scan tool to the vehicle.
•With a master passkey III key, turn ON the ignition with the engine OFF.
•With a scan tool, select Program ECU under Service Programming System.
•At this point the scan tool must remain connected for the duration of the 10-minute relearn procedure.
Important: On some vehicles the SECURITY telltale maybe illuminated on steady for the duration of the 10-minute relearn procedure.
•Observe the scan tool, after approximately 10 minutes the scan tool will display "Programming Successful, Turn OFF Ignition". The vehicle is now ready to relearn the key information and/or the passwords on the next ignition switch transition from OFF to ON.
•Turn OFF the ignition and wait 5 seconds.
•With a master Passkey III key, start the vehicle. The theft deterrent control module has now learned the key transponder information and the PCM has now learned the fuel continue password.
Important: Perform this step ONLY on vehicles with EXPORT and Canadian configured theft deterrent control modules.
•Turn OFF the ignition and wait 15 seconds minimum.
Important: Perform this step ONLY on vehicles with EXPORT and Canadian configured theft deterrent control modules.
•With a second master passkey III key, start the vehicle. The theft deterrent control module has now learned the second master Passkey III key transponder information
•With a scan tool, clear any DTCs.
30-Minute Relearn Procedure
Use this procedure after replacing the following components:
• The passkey III (PK3) keys
• The theft deterrent control module
• The PCM, see important above
Important: This procedure is not available on vehicles equipped with option code (Z49 or BAE).
If replacing a theft deterrent control module with an GM SPO Replacement Part, perform the procedure to setup a new theft deterrent control module prior to the 30-minute relearn procedure.
•With a master passkey III key (Black), turn ON the ignition, with the engine OFF.
•Observe the Security telltale, after approximately 10 minutes the telltale will turn off.
•Turn OFF the ignition, and wait 5 seconds.
•Repeat steps 1-3 two more times for a total of 3 cycles or 30 minutes.
Important: The vehicle learns the key transponder information and/or passwords on the ignition switch transition from OFF to CRANK. You must turn the ignition OFF before attempting to start the vehicle.
•With a master passkey III key, start the vehicle. The vehicle has now learned the key transponder information and the PCM has now learned the fuel continue password.
•With a scan tool, clear any DTCs.
