If you're familiar with passkey III then help me out.

I put in the key on a 2000 buick, the security light is blinking, the car functions normally otherwise - until I go to start it. I turn the ignition forward and zap - the whole car turns off. Nothing. Not even an attempt at turning the starter. Now, giving the battery a jump-start actually works to get around this worthless security feature.

Does passkey actually turn off the car entirely??
 
Go look at the positive battery terminal.Ill bet its all green an powdery white.I have werked at GM dealer for 3 years now.very common for the corrosion build up UNDER the stupid rubber boot.I actually believe it PROMOTES corrosion.Pull off the + battery cable and inspect the bolt-ecpecially if its black-that meens the terminal at the battery case is leaking.Again very common on GM's>AND no the passkey feature disables the starter an the PCM doesn't comand the fuel pump relay OR the injectors to pulse.But all else will werk+radio,lights,windows,ETC......
 
kubastic..I amloged into GM dealer website for service as we type.I can realy some info to ya if ya like HELL i can even tell you your warranty history for ya while im at it.just need yer vin number!!!:spin3: plus i need to know what buick you have,you didnt specify
 
well, the terminals weren't green but I fiddled with them. Had the door wide open. Nothing.

But I closed and then opened the door. And it was on again. I'm speechless. Started up.

2000 park avenue. If you have any tips for me I'm interested though. I have a whole mess of keys from the used car dealer: some say PK3, some say GM PK3 M, and others have no markings.

2000 Buick Park Avenue Vehicle Theft Deterrent (VTD) Description

The vehicle VTD functions are provided by the Pass-Key® III system. Pass-Key® III consists of an ignition key with a transponder embedded in the head, the VTD Controller Module, the exciter assembly, and the PCM.
The exciter assembly is an antenna which is made up of wire coils which surround the ignition lock cylinder. These coils, powered by the VTD Controller Module, emit electromagnetic energy which energizes the transponder pellet within the head of the key. The energized transponder transmits a unique value by radio frequency which is detected by the exciter. The VTD Controller Module receives and compares this value to one stored in memory (a learned value). If the received transponder value matches a learned value, the VTD Controller Module sends a password via the class 2 serial data line to the PCM. The PCM compares this password to one stored in memory (a learned password). If the passwords match the PCM enables engine starting.
This password is unique for each VTD Controller Module along with the unique value of the key's transponder. This method prevents swapping one of the following modules in order to start the vehicle:
• The VTD Controller Module -- which must receive the unique key value and then sends a unique password.
• The PCM -- which must receive the correct password from the VTD Controller Module to enable engine starting.​

The ignition key for PASS-Key® III equipped vehicles is a typical looking ignition key with a transponder located in the plastic end of the key. The transponder value is fixed and unable to be changed. The PASS-Key® III system uses the ignition key transponder value to determine if a valid ignition key is being used to start the vehicle. There are approximately 3 trillion possible transponder values. There are no visible electrical contacts. The keys may be identified by the letters PK3 stamped into the steel shank of the key. PASS-Key® III systems use the following types of ignition keys:

Master Keys Master keys (black plastic end) are for full access operation of the vehicle. Master keys may perform the following functions
• Start the vehicle.
• Lock/unlock all of the door locks.
• Lock/unlock all of the storage compartments.
• Lock/unlock the rear compartment lid lock.
• Lock/unlock the rear compartment valet lock out switch, which is located on the IP.​

Valet Keys Valet keys (gray plastic end) are for restricted operation of the vehicle.
• The valet key may perform the following functions:
- Start the vehicle.
- Lock/unlock all of the door locks.
• The valet key cannot perform the following functions:
- Lock/unlock all of the storage compartments.
- Lock/unlock the rear compartment lid lock.
- Lock/unlock the rear compartment valet lock out switch, which is located on the IP.​
<A href="http://service.gm.com/servlets/BlobShtml?ShtmlFile=591479&evc=sm&pubid=146&cellId=59265&mspsdsubkey=960#ss2-591479">Ignition Lock Cylinder

The ignition lock cylinder performs all of the functions of a lock cylinder on a non PASS-Key® III vehicle. The ignition lock cylinder for vehicles with Pass-Key® III may be located on the steering column or on the instrument panel. In either location the exciter coils surround the ignition lock cylinder such that they are very close to the head of the key which contains the transponder pellet.
If an ignition lock cylinder is replaced, new Pass-Key® III keys must be cut to match the mechanical coding of the new lock cylinder. The new keys must be learned by the VTD (Pass-Key® III) Module. When replacing an ignition lock cylinder, refer to Programming Theft Deterrent System Components .
<A href="http://service.gm.com/servlets/BlobShtml?ShtmlFile=591479&evc=sm&pubid=146&cellId=59265&mspsdsubkey=960#ss3-591479">VTD (Pass-Key® III) Module and Exciter

Vehicles with steering column mounted ignition switches have the exciter integral with the VTD (Pass-Key® III) Module which is located within the steering column. Vehicles with instrument panel mounted ignition switches have exciter modules separate from the VTD (Pass-Key® III) Module with the vehicle wiring harness connecting the two. The VTD (Pass-Key® III) Module for vehicles with instrument panel mounted ignition switches is located within the instrument panel.
The VTD (Pass-Key® III) Module can learn up to ten keys (transponder values).
The VTD (Pass-Key® III) Module provides the signal to the exciter which energizes the transponder within the key. It also receives and verifies the transponder signal value. When the VTD (Pass-Key® III) Module has verified that the transponder signal value matches the value of a learned key, it sends an enable password to the PCM via the class 2 serial data line. If the transponder value is not correct, it sends a disable password to the PCM.
<A href="http://service.gm.com/servlets/BlobShtml?ShtmlFile=591479&evc=sm&pubid=146&cellId=59265&mspsdsubkey=960#ss4-591479">Powertrain Control Module (PCM)

The PCM verifies that the password received from the VTD (Pass-Key® III) Module via the Class 2 serial data line is correct. The VTD (Pass-Key® III) Module can learn only one enable password. If the enable password is correct, the PCM enables the fuel system and engine starting system.
The PCM disables the fuel and starting systems if any of the following conditions occur:
• The enable password incorrect.
• The system disable password is sent by the VTD (Pass-Key® III) Module.
• No passwords are received -- there is no communication with the VTD (Pass-Key® III) Module.​

Important

  • If replacing a theft deterrent control module with a GM Service Parts Operation (SPO) replacement part, the module will learn keys immediately. The existing PCM however, must learn the new fuel continue password when the theft deterrent control module is replaced.
  • If replacing a PCM with a GM SPO replacement part, after programming, these modules will learn the incoming fuel continue password immediately upon receipt of a password message. Once a password message is received, and a password is learned, a learn procedure must be performed in order to change this password again. A PCM which has been previously installed in another vehicle will have learned the other vehicles fuel continue password and will require a learn procedure after programming in order to learn the current vehicle's password.
  • When performing the 10 minute or the 30 minute re-learn procedures, all previously learned keys will be erased from the VTD module's memory.
  • Additional keys may be learned immediately after the 10 minute or 30 minute re-learn procedure by inserting the additional key to be learned and turning the ignition to the RUN position within 10 seconds of removing the previously learned key.
  • When performing the 10 minute or the 30 minute re-learn procedures, use only a master key (black) during the procedure. If a valet key (gray) is learned first, the VTD module will not allow additional keys to be learned.
<A href="http://service.gm.com/servlets/BlobShtml?ShtmlFile=850020&pubid=146&evc=sm&cellId=59393#ss1-850020">10 Minute Re-Learn Procedure

Use this procedure after replacing any of the following components:
  • The keys
  • The theft deterrent control module
  • The PCM if necessary, refer to the Important statement above
  • Tools Required
  • Tech 2 Diagnostic Tool
  • Techline Terminal with current service programing system (SPS) software
  1. <LI type=1>Connect the Tech 2 Diagnostic tool. <LI type=1>Select Request Information under Service Programing. <LI type=1>Disconnect the Tech 2 from the vehicle and connect the Tech 2 to a Techline Terminal. <LI type=1>On the Techline Terminal, select Theft Module Re-Learn under Service Programming. <LI type=1>Disconnect the Tech 2 from the Techline Terminal and re-connect the Tech 2 to the vehicle. <LI type=1>Turn ON the ignition, with the engine OFF, using a master Pass-Key® III key (black). <LI type=1>Select VTD Re-Learn under Service Programming. <LI type=1>At this point the Tech 2 must remain connected for the duration of the 10 minute re-learn period. <LI type=1>Observe the security telltale. After approximately 10 minutes the telltale will turn off. The vehicle is now ready to re-learn the key information and passwords on the next ignition switch transition from OFF to CRANK. <LI type=1>Turn OFF the ignition and wait 5 seconds. <LI type=1>Start the vehicle. The scan tool has now learned the key and password information.
  2. Clear any DTCs using the scan tool.
<A href="http://service.gm.com/servlets/BlobShtml?ShtmlFile=850020&pubid=146&evc=sm&cellId=59393#ss2-850020">30 Minute Re-Learn Procedure

Use this procedure after replacing any of the following components:
  • The keys
  • The theft deterrent control module
  • The PCM if necessary, refer to the Important statements above
  1. <LI type=1>Turn ON the ignition, with the engine OFF, using a master Pass-Key® III key (black). <LI type=1>Observe the security telltale. After approximately 10 minutes the telltale will turn off. <LI type=1>Turn OFF the ignition, and wait 5 seconds. <LI type=1>Repeat step 1-3 two more times, for a total of 3 cycles or 30 minutes.
    Important

    The vehicle learns the key 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.

    <LI type=1>Start the vehicle. The vehicle has now learned the key and password information.
  2. Clear any DTCs using the scan tool.
<A href="http://service.gm.com/servlets/BlobShtml?ShtmlFile=850020&pubid=146&evc=sm&cellId=59393#ss3-850020">Quick Learn Procedure - Keys Only


Important

  • Additional master theft deterrent control keys (black) or valet keys (gray) may be added, up to 10 keys, using this procedure when there is an available learned master theft deterrent control key (black).
  • This procedure adds keys only. This procedure does not erase previously learned keys.
  • The keys to be learned must duplicate the mechanical cut of the current key.
  • If more than one valet key (gray) is to be learned, each valet key must be immediately preceded by a learned master theft deterrent control key (black).
  1. <LI type=1>With a previously learned master theft deterrent control key (black), turn ON the ignition, with the engine OFF. <LI type=1>Turn OFF the ignition and remove the key.
  2. Within 10 seconds, insert the key to be learned (black or gray) and turn ON the ignition, with the engine OFF. The vehicle has now learned the new key.

2000 Buick Park Avenue Vehicle Theft Deterrent (VTD) Operation

When an ignition key is inserted into the ignition lock cylinder, the transponder embedded in the head of the key is energized by the exciter coils surrounding the ignition lock cylinder. The energized transponder transmits a signal that contains its unique value, which is received by the theft deterrent controller module. The theft deterrent controller module then compares this value to a value stored in memory and performs one of the following functions:
  • If the transponder value is correct, the theft deterrent controller module sends a class 2 message containing the module's unique enable password to the PCM.
  • If the transponder value is incorrect, the theft deterrent controller module sends a class 2 message containing a disable password to the PCM.
  • If the theft deterrent controller module is unable to measure the ignition key transponder value for one second (due to a damaged or missing pellet or a damaged exciter), the module sends a class 2 message containing a disable password to the PCM
    Important

    If the theft deterrent controller module is unable to measure the ignition key transponder value for 30 consecutive seconds, after the vehicle has started, the module will consider itself malfunctioning and enter a fail enable state and illuminate the Security Indicator. The vehicle will not stall or stop running. If the theft deterrent controller module is in a fail enable state when the ignition is turned to OFF, it will remain fail enabled until the next time the vehicle is started. If the theft deterrent controller module is fail enabled the theft deterrent system is NOT active and the vehicle will start. The module WILL send its enable password even if a transponder value is not received. The theft deterrent controller module will remain fail enabled until the module measures a valid key transponder value.
When the PCM receives a password from the theft deterrent controller module, the PCM compares the password to a password stored in its memory (learned password) and performs one of the following functions:
  • If the PCM receives a correct system enable password, indicating a learned theft deterrent controller module has read a valid transponder value, fuel and starting are enabled.
  • If the PCM receives a system disable password, indicating a theft deterrent controller module has read an invalid transponder value, fuel and starting are disabled.
  • If the PCM receives an incorrect password, indicating a theft deterrent controller module that has not been learned by the PCM, fuel and starting are disabled.
  • If the PCM has no communication with the theft deterrent controller module, fuel and starting are disabled.
    Important

    If the PCM is unable to communicate with the theft deterrent controller module (loss of class 2 state of health) after the vehicle has started, the module will consider itself malfunctioning and enter a fail enable state and illuminate the Security Indicator. The vehicle will not stall or stop running. If the PCM is in a fail enable state when the ignition is turned to OFF, the PCM will remain fail enabled until the next time the vehicle is started. If the PCM is fail enabled the theft deterrent system is NOT active and the vehicle will start. The PCM will remain fail enabled until class 2 communication with the theft deterrent controller module is restored.
<A href="http://service.gm.com/servlets/BlobShtml?ShtmlFile=850229&evc=sm&pubid=146&cellId=59266&mspsdsubkey=960#ss1-850229">SECURITY Indicator Operation

The theft deterrent controller module can command the instrument cluster to illuminate the SECURITY indicator only when the ignition key is in the ON position. If the PCM loses communication with the theft deterrent controller module, the instrument cluster will also detect the loss of communication and will illuminate the SECURITY indicator. The SECURITY indicator can indicate both malfunctions-indicator on steady, and tamper-indicator flashing, indicating unauthorized operation. Under the following conditions the SECURITY indicator may be commanded to illuminate.
SECURITY Indicator Stays Illuminated and Engine Starts If the theft deterrent controller module was unable to measure the ignition key transponder value or the PCM lost communication with the theft deterrent controller module while the engine was last running, the indicator will remain illuminated during subsequent ignition cycles. This is to remind the driver that the vehicle theft deterrent system will not be functioning until the problem is corrected. The vehicle is fail enabled and will start.
SECURITY Indicator Illuminates when Engine is Running If the theft deterrent controller module is unable to measure the ignition key transponder value or the PCM loses communication with the theft deterrent controller module while the engine is running, the indicator will be illuminated. If the key is turned to OFF, the vehicle will be fail enabled and will start if the condition still exists at the next attempt to start the vehicle.
SECURITY Indicator Illuminated and Engine Does Not Start The theft deterrent controller module or the PCM has detected a problem with the theft deterrent system. The theft deterrent controller module is unable to measure the ignition key transponder value. The System is in Learn Mode, refer to Programming Theft Deterrent System Components .
SECURITY Indicator Flashes and Engine Does Not Start The theft deterrent controller module has measured an incorrect transponder value when the ignition key is turned to the ON position. The transponder has not been learned by the theft deterrent controller module. This is considered a tamper condition by the module.
