The PassLock system works when the lock cylinder moves a magnet past a Hall effect sensor. The sensor then sends a signal to the control, which GM has moved several times over the model years. The control then sends the code to the PCM. If the code is correct, the PCM will allow the car to start and run.
- PassLock Versus PassKey GM used two strategies to determine if someone was trying to steal the vehicle. The early systems used the first generation PassKey system. Then GM changed to the PassLock system.
What is GM passkey?
The PassLock system was designed to prevent vehicle theft by disabling fuel to the engine if attempts are made to start the vehicle without the correct bitted key.
What is a passkey on a car?
Some GM vehicles come with a factory-installed anti-theft system commonly referred to as the passlock or passkey. When this happens, the security (theft sys) light randomly illuminates on the dashboard, and the car will not start.
How do I bypass a passlock GM?
How to Disable a GM PassLock System
- Leave the ignition key turned to the ‘On’ position after the vehicle has stalled and will not start.
- Look at the dashboard and locate the theft system light.
- Turn the ignition to the ‘Off’ position to disable the PassLock system, and wait for 20 seconds for the system to reset.
What is a ignition passlock sensor?
In normal operation, the key turns the ignition lock cylinder. The Passlock sensor monitors the position of the lock cylinder and relays an analog Passlock signal to the body control module (BCM). The BCM determines the validity of the Passlock signal, then sends a password to the powertrain control module (PCM).
Does passlock disable fuel pump?
Yes, the fuel pump should still run even if there is a passlock issue.
Where is the passlock module located?
There is only one PassLock system. There is no sensor in the ignition lock cylinder, the Passlock sensor is in the ignition lock cylinder housing, and there is a magnet in the ignition lock cylinder.
How does Chevy passlock work?
The PassLock system works when the lock cylinder moves a magnet past a Hall effect sensor. The sensor then sends a signal to the control, which GM has moved several times over the model years. The control then sends the code to the PCM. If the code is correct, the PCM will allow the car to start and run.
Can you disable passlock?
The Passlock system on a Vehicles is the anti-theft system. The Passlock system uses a recognition transponder in the ignition tumbler and a computer chip in the ignition key. While you cannot remove the Passlock system, you can disable it by tricking it into thinking the Vehicles had a malfunction.
How do I reset my GM security system?
How do you reset the Chevy Silverado’s anti-theft system? Insert the ignition key, put it in the on position, attempt to start the engine. With the key in that position, wait ten minutes. The security light will blink and go out.

- No Noise From The Starter.
- Dashboard Lights Flicker.
How do you relearn a Chevy key?
Relearn procedure: Insert ignition key and turn to the ON position. Do not attempt to start the engine. Leave the key in the ON position for approximately 11 minutes. The security light will be on or flashing for the 11-minute period.
GM PassKey and PassLock overview
On its automobiles, General Motors has installed a number of anti-theft devices. When your vehicle does not start, starts intermittently, or starts and then dies, you should first establish whether GM anti-theft system is in use on the vehicle. After that, you should diagnose the anti-theft system before you begin replacing the starter components. A flashing ‘Theft’ light on your dashboard is a telltale indicator that you have an anti-theft problem. A quick overview of each system and what to look for is provided below.
There are a few that deactivate the engine starter, and others that enable it while disabling the gasoline injectors.
In order to properly comprehend the differences in car theft deterrent systems, first understand what they are.
PassLock Versus PassKey
GM employed two ways in order to assess whether or not someone was attempting to steal the car. The PassKey mechanism of the first generation was employed in the early systems. Then General Motors switched to the PassLock system. The PK3 mark on the shank of PassKey III transponder keys distinguishes them from other transponder keys. Keep an eye out for the resistor pellet that is mounted on the key’s shaft to the left of the plastic cover.
During the initial generation of PassKey systems, a resistor pellet was placed into the head of the key. The resistor made contact with the lock cylinder’s terminals, and the system was able to determine the resistance value of the resistor pellet. Because of the high failure rate of these systems, General Motors switched to the PassLock system.
In order to disable PassLock systems, automobile thieves must first remove the lock cylinder from the casing with the use of a slide hammer before attempting to turn the ignition switch with needle nose pliers. The PassLock system operates by moving a magnet through a Hall effect sensor when the lock cylinder is turned. It then transmits a signal to the control, which General Motors has shifted multiple times throughout the course of the vehicle’s model years. After that, the control transmits the code to the PCM.
While it is true that pulling the lock cylinder removes the magnet as well, the sensor is not able to detect any movement of the magnet because of this.
Because the Hall effect sensor cannot be changed independently from the lock cylinder housing, the shop would have to replace the lock cylinder housing in order to fix the system.
In PassKey III, General Motors included a transponder into the key head. As the driver approaches the lock cylinder with the key, a transmitter transmits an interrogation signal to the transponder key, which responds with a response. The transmitter is housed within a ring that surrounds the outside edge of the lock cylinder’s cylindrical body. The interrogation signal is received by the transponder, which answers with a coded response message. The message is checked to see if it received an appropriate answer.
- If this is not done, the car may start, but it may stall within seconds of starting.
- The key contained a pellet that was factory-installed in the vehicle’s anti-theft module to prevent theft.
- It was not possible to execute a ‘relearn’ on the system.
- When you look at the key, you will be able to tell which system it is.
- After initial startup, the system activates the starter, but after a few seconds, it turns off the injectors.
- This system has a ‘relearn’ function.

- When the key is placed in close proximity to the lock cylinder receiver module, it activates the transponder, which then transmits a coded signal to the receiver module.
- The module then sends a signal to the PCM to turn on the engine if this is the case.
- When testing this system, an ohmmeter will not work.
- If the signal is incorrect, the PCM shuts the injector and the starter and flashes the LED once per second until the problem is corrected.
The system is installed on the following vehicles:BuickLesabre 2000-onPark Avenue 97-onCadillac Oldsmobile 98-onDeville 2000-onSeville 98-on Pontiac 01-on-Aurora 01-on-Aurora 01-on-Aurora 01-on-Aurora 01-on-Aurora 01-on-Aurora 01-on-Aurora 01-on-Aurora 01-on-Aurora 01-on-Aurora 01-on-Aurora 01-on-Aurora 01-on-Aurora 01-on-Aurora 01-on-Aurora 01-on- Bonneville 2000 and later General Motors minivans Venture, Montana, and Silhouette are all excellent choices.
- Passlock This system permits starter functioning for 1-2 seconds after startup, after which it disables the injectors.
- The key cylinder casing has a tiny magnet, which rotates past the Passlock sensor when the key is turned.
- The voltage on the sensor is then reduced to a predetermined level (there are 10 different values).
- This technique is essentially checking to make sure that a criminal hasn’t popped the lock cylinder and taken possession of the car.
The Passlock system was installed in the following vehicles: Buick Skylark 96-98 (Skylark 96-98) Chevrolet From 1995 to the present, the Cavalier 95, the Impala 2000, the Malibu 97, the Monte Carlo 2000, and the Oldsmobile Cutlass 97-onIntrigue 98-onAchieva 96-onCutlass 97-onAll GM trucks 98-on DIAGNOSTICS OF THE SYSTEM System Diagnostics for the PassKey I and II There are 15 distinct key codes to choose from.
- Connecting an ohmmeter to either side of the key pellet will allow you to determine the resistance of the key pellet.
- Once you’ve located the resistance value, replace the lower dash panels.
- Then, using an ohmmeter, measure the resistance of the electrical connector and insert the key.
- If not, repeat the process.
- The reading shown on your meter should not alter or go out of range.
- It is NOT UNCOMMON for the wires to come loose from the key cylinder.
- Now flip the ignition switch to the RUN position while you conduct a voltage test between the dark blue wire in the theft deterrent electrical connector (the one that was just removed from the vehicle) and a ground point.
The dark blue wire should be connected to the PCM that supplies the module with power.
If you DO obtain the 5 volts, turn off the ignition and reattach the electrical connector to the battery.
Set the ignition to the RUN position.
If this is the case, the stolen module should be replaced.
If it has passed the test, you can proceed.
The way it works is as follows: The resistance of the pellet in the key is read by the lock cylinder, which then transmits that information to the theft module.
After determining that the correct key has been inserted, the theft module partially grounds the voltage on the dark blue wire.
That’s why you get a crank, start, and engine shut down sequence of events. As a result, if the vehicle starts and then shuts down, AND THE THEFT LIGHT FLASHES, either the module is not receiving the proper signal from the lock cylinder or the module is defective.
A transponder was integrated into the key head of the PassKey III. A transmitter transmits an interrogation signal to the transponder key when the driver pushes the key near the lock cylinder. Located on the exterior edge of the lock cylinder, in a ring around it, is the transmitter. The interrogation signal is received by the transponder, which responds with a coded response message in response. An examination of the message is carried out to ensure that it has received an appropriate response.
- The car may start if this is not the case, but it will stall in a matter of seconds.
- The VAT stands for vehicle anti-theft.
- It is possible to deactivate the starter and destroy the injectors if the lock cylinder is rotated or bypassed when no key is put in the ignition system.
- A pellet key was used in both the PassKey I and IIS systems, which were similar to the VATS system.
- It is made up of a black resistor pellet with a thin metal edge extending along the length of the keyboard.
- Consequently, the car would start, but then stop working completely ‘Relearn’ is a feature included in this system.

The receiver module is situated just next to the lock cylinder on the vehicle.
In order to determine whether or not the signal is valid, the receiver module examines its memory.
A steady indication light will illuminate for two seconds if the value entered is correct.
A scan tool is required.
Whenever an unauthorized key is pressed or a system malfunction occurs, the light flashes twice per second.
Passlock Approximately 1-2 seconds after initiation, this mechanism permits the starter to function before shutting down the injectors.
Powered by electricity, the sensor detects the movement of the object.
The key does not contain any pellets.
Performing a relearn operation on the Powertrain Control Module (PCM) is necessary (need a programming scan tool).
Chevrolet From 1995 to the present, the Cavalier 95, the Impala 2000, the Malibu 97, the Monte Carlo 2000, and the Oldsmobile 95.
There are a total of 15 key codes available.
To determine the resistance value, first remove the lower dash panels and look for two little wires (both white) that go down the base of the steering column.
The electrical connector where those lines come to a close should be disconnected.
Resistance values obtained from the key should be matched by the reading you obtain at the end of the two white wires.
Turn the ignition key to start the engine.
The key cylinder will need to be replaced if this happens.
You should do these tests if you have a PassKey system in your vehicle, and your engine starts, runs, and then stops AND your THEFT light is illuminated (for around 5 seconds).
In this case, 5 volts should be displayed on the screen.
If you do not get this voltage, check for an open or short between this wire and the PCM.
Pierce the insulation on the same wire (with a pin) or back-probe the wire in the connection to determine the cause of the problem.
The voltage reading should now be 2.5 volts, according to the instructions.
That is presuming you have previously performed the key pellet test (described above) and that the pellet passes the test.
Alternatively, if you detect 2.5 volts but the car still won’t start, the fuel pump relay may be defective.
The resistance of the pellet in the key is read by the lock cylinder, which then communicates the information to the theft detection module.
As soon as the theft module judges that the correct key has been entered, it partly grounds the voltage on the dark blue wire.
Because of this, the engine starts, then shuts down once a cranking motion is applied. The theft light will flash when the car begins and then stops due to a problem with the module receiving the right signal from the lock cylinder or a faulty module.
A transponder was built into the key head of the PassKey III. As the motorist approaches the lock cylinder with the key, a transmitter transmits an interrogation signal to the transponder key. Located on the exterior edge of the lock cylinder, in a ring around it, is the transmitter. The interrogation signal is received by the transponder, which answers with a coded message. The message is checked to ensure that it received a valid answer. If everything is in order, the car will start and operate.
- VAT The VAT, also known as vehicle anti-theft, was employed primarily on Corvettes from 1986 to 1988.
- It is possible to deactivate the starting and injectors if the lock cylinder is rotated or bypassed without the right key attached.
- PassKey I and IISimilar to the VATS system, these cars also made use of a pellet key.
- It is made up of a black resistor pellet with a thin metal edge extending down the length of the keyhole.
- As a result, the car would start and then die.
- It was employed on these automobiles.
- Chevrolet Corvette 89-01Camaro/Impala 94-96Camaro/Impala It’s the Lumina/Monte Carlo 95-97.
This method makes use of a specific key (with the number PK3 printed on the shoulder of the key) that has a transponder hidden behind the rubber cover.
When the key is placed close to the lock cylinder receiver module, it activates the transponder, which then transmits a coded signal to the receiver.
If this is the case, the module sends a signal to the PCM, instructing it to enable the engine.
This system cannot be tested using an ohmmeter.
If the signal is not right, the PCM shuts the injector and the starter and flashes the LED once per second.
The system is installed in the following vehicles:BuickLesabre 2000-onPark Avenue 97-onCadillac Oldsmobile 98-onDeville 2000-onSeville Pontiac 01-on-Aurora 01-on-Aurora 01-on-Pontiac 01-on-Aurora 01-on-Aurora 01-on-Aurora 01-on-Aurora 01-on-Aurora 01-on-Aurora 01-on-Aurora 01-on-Aurora 01-on-Aurora 01-on-Aurora 01-on-Aurora 01-on-Aurora 01- Bonneville 2000 and later General Motors Minivans Venture, Montana, and Silhouette are examples of such names.
- Passlock This method allows the starter to operate for 1-2 seconds before shutting off the injectors.
- The key cylinder casing has a tiny magnet that moves past the Passlock sensor when the key is turned on.
- After that, the voltage on the sensor lowers to a certain level (there are 10 different values).
- This technique is essentially checking to make sure that a criminal hasn’t popped the lock cylinder in order to take the car.
The following vehicles were equipped with the Passlock system: Buick Skylarks 96-98 (Skylarks 96-98) Chevrolet From 1995 to the present, the Cavalier 95, the Impala 2000, the Malibu 97, the Monte Carlo 2000, the Oldsmobile Achieva 96-on, Cutlass 97-on, Intrigue 98-on, and all General Motors trucks 98-on DIAGNOSTICS OF SYSTEMS System Diagnostics for PassKey I and II There are a total of 15 key codes.
- By attaching an ohmmeter to either side of the key pellet, you can determine the resistance of the key pellet.
- Once you’ve found the resistance value, replace the lower dash panels.
- Then, using an ohmmeter, measure the resistance of the electrical connector and then insert the key.
- Then you’ll need to turn the key.
- The key cylinder will have to be replaced if this occurs.
- If you have the PassKey system and the engine cranks, runs, and then stops AND the THEFT light is illuminated (for around 5 seconds), the following checks should be carried out: Remove the electrical connector from the deterrent module (step 1).
- You should notice a voltage of 5 volts.
If you do not get this voltage, check for an open or short between the dark blue wire and the PCM.
Pierce the insulation on the same wire (with a pin) or back-probe the wire in the connection to determine the cause of the short.
After this, the voltage should read 2.5 volts.
That is supposing that you have previously performed the key pellet test (as described above) and that the pellet passes the test.
This is how it works: The resistance of the pellet in the key is read by the lock cylinder, which then communicates the information to the theft module.
After determining that the appropriate key has been entered, the theft module partly grounds the voltage on the dark blue wire.
In order to do this, you will hear a crank, start, and engine shut down. As a result, if the vehicle starts and then stops, AND THE THEFT LIGHT FLASHES, either the module is not receiving the necessary signal from the lock cylinder or the module is faulty.
General Motors Vehicles Equipped with PASSLock
In order to prevent car theft, the PassLock system disables gasoline to the engine if an attempt is made to start the vehicle without the proper key. In addition to increasing the degree of protection, PASSLock does so while maintaining the simplicity of servicing and low costs associated with typical ignition lock systems. PassLock’s security is embedded into the lock itself, as opposed to the General Motors’ PASSKey I/II, VATS, PASSKey III, or keyless systems, which are all dependent on an additional key or device.
- It is not necessary to program the PASSLock-equipped car in order for it to accept additional keys.
- General Motors launched the PASSLock ignition lock for the 1995-1/2 model year, which was the first ignition lock to be fitted with a magnet installed inside the ignition lock cylinder and a matching Hall-effect sensor mounted into the ignition lock housing assembly.
- The sensor electronically communicates with the vehicle’s on-board computer, and the fuel supply is maintained if the electronic value obtained by the sensor matches the code recorded in the vehicle’s on-board computer If the values do not match, the fuel supply is cut off immediately.
- It is the design of the PASSLock system that hard rotation will generally destroy the electronics, rendering the car immobile in most cases.
- Note: After the engine is started, the PASSLock System’s theft deterrence feature shuts out the gasoline injectors, therefore preventing theft.
- The engine will then come to a complete stop.
- PassLock ignition locks are available in three primary styles: modular, modular in-dash, and CSS.
When selecting a replacement ignition lock, double-check that the component number matches the year, make, and model of your vehicle.
In most cases, installing the improper ignition lock will result in the car being unable to be used.
This depends on the year and the model.
These ignition locks do not require any wire to be connected, and neither do the CSS ignition lock cylinders that are included with the lock.
Replacement locks do not have a sensor value associated with them.
The vehicle must be set to accept the new lock.
Only the plug needs to be changed.
To reprogram the PASSLock I ignition lock, follow these steps: Step 1.
A one-in-ten possibility exists that the vehicle will start.
Continue to operate the vehicle with the ignition in the ON or RUN position.
It is possible to start the automobile.
The following programming process should be followed to the letter.
After reinstalling the lock, try to start the car using a key that has been properly cut.
Secondly, if the new lock does not correspond to the electronic value stored in the vehicle’s computer, an indicator light on the instrument panel will begin blinking, and the vehicle will be rendered inoperable.
Step 4: The light will stop flashing and turn off after roughly 10 minutes.
Step number six.
Step number seven.
Step number eight.
The onboard computer has been set to accept the signal from the new lock at this point.
On rare occasions, a car equipped with PASSLock will experience difficulties starting.
It is impossible for PASSLock to generate this circumstance if the car would not crank.
The instrument panel of the majority of PASSLock-equipped automobiles contains a telltale sign.
In order to avoid confusion, a ‘No Start’ condition should not be mistaken for a PASSLock System error.

Truck wont start. PassLock Security issues
I’ll try to keep this as quick as possible. 2003 Chevrolet Silverado 2500HD Crew Cab 8.1L I recently purchased a pickup (about a month ago). Until approximately two weeks ago, the truck was in perfect working order. When I attempted to start the truck, it would splutter and die. When I attempted it again, it would attempt to run and then die. (behaved as though it were about to run out of gas) Allowing the truck to sit overnight resulted in no problems the following day. (Because the scenario was unfamiliar to me, I did not pay attention to the security light.) I did find it weird that the plastic on the column was only half on, which led me to believe that the prior owner was having some type of trouble.
- I was attempting to figure out why the passenger seat (which is motorized) was not working.
- I was a complete moron.
- When I went out to perform an errand a short time later, the vehicle was experiencing the same problem.
- As a result, I now pay close attention to the security light.
- The truck is still not starting.
- I tried it, but it didn’t work.
- The truck would only crank at this point.
- It was almost as if it had run out of gas before.
- So I used a scan tool to look for P1631 and B2948, which I discovered.
- As a result, I came here in search of advice and assistance.

If you’re using passwords, how frequently should you update them? Changing our passwords on a regular basis is something we all know we should do, but how frequently is ‘often’ enough? Some people never change their passwords, and even worse, they reuse the same (or similar) passwords across all of their internet accounts, making them vulnerable to identity theft. This is a dangerous activity that has the potential to result in data breaches, identity theft, and other problems. Ordinary individuals, on the other hand, have a habit of forgetting their passwords.
Security breaches and cybercrime are on the rise, which is a significant concern in the world today.
The first step in securing your credentials and personal information is to make sure that your passwords are secure.
Examine some of the most important password tips, as well as how our Password Manager may assist you in regaining control of your online credentials, in more detail below.
As passwords get more difficult to break, the means for doing so become more sophisticated.
It is common for individuals and corporations to forget that their users are the first line of protection against cybercrime.
Despite the fact that the Better Business Bureau suggests changing your password at least once a year, this is outdated advice.
To begin with, most IT specialists recommend changing your password every thirty, sixty, or ninety days.
Using a password manager, you won39;t have to worry about coming up with a strong combination of characters, symbols, and numbers because the software will generate them for you.
If you don’t utilize a password manager, you’ll find yourself using recycled passwords more frequently, and you’ll even find yourself forgetting certain passwords.
Using a password manager gives the level of protection you need to keep your personal information safe from hackers.
So, when is the most appropriate moment to change your password?
Now, let39;s take a look at some of the most prevalent instances in which a password change is necessary.
When a company discloses a data breach, you should change your password as soon as possible to ensure that your personal information is kept safe from hackers.
If You Have Reason to Suspect Illegal Access: Do not wait until there is concrete evidence of unauthorized access to your account before taking steps to protect yourself (s).
If you believe that someone is attempting or has attempted to get access to one or more of your accounts, change your passwords as soon as possible.
If You Discover Malware or Other Phishing Software: A virus is a piece of software that may corrupt your computer and reveal your personal information to third parties.

- Corrosion on the tin contacts may be repaired for approximately $1.50 if you apply dielectric grease on the inside of the contacts to the inside of the contacts. The issue has been resolved. The issue is not with the passlock mechanism or the tumbler. When the ECU is connected to the key tumbler, a wire is used to link the two devices, and the contacts are made of tin, which eventually corrodes. Make use of a wire cleaner to clean the contacts, and then coat them with dielectric oil to prevent further corrosion. Many people have said that they walked into a dealer and paid 500 dollars, just to have the same thing occur once again within a month. DO NOT TRAVEL TO THE DEALERSHIP
- Passkey 2 Bypass – This repair demonstrates how to resolve this issue on the Grand Am model. My Impala is equipped with the same approach that I used on it: Passlock System Major Design Flaw and How To Fix It- My attention was drawn to a few fascinating aspects of the PassLock system design when the ignition switch was disassembled and inspected more carefully. In the case of the male connection, it does not fit snugly into the female connector receptacle. It has the ability to wriggle up and down as well as back and forth. 2) The connection is a ‘blind connection,’ which means that throughout the assembly process, one would not be able to see if the PassLock connector was properly attached or not. 3) The male and female pins that are utilized in the PassLock system are ‘Tin’ plated, which means that they will oxidize over time. The pins should have been ‘gold plated,’ as the phrase goes. Under a 10X magnification, the grey oxidation was plainly distinguishable. In addition, the Body Computer does not adapt over time to account for the oxidation that accumulates on the PassLock pins. The vital analog PassLock signal wanders as a result of mechanical difficulties, temperature, and humidity variations. Okay – General Manager – The PassLock cat has escaped from its cage! What I did to resolve the situation. Without a certain, I did not take the car to any General Motors dealership and have it ‘rear-ended.’ PassLock sensor was connected to the three wires (black, white and yellow) using a simple hand soldering technique. When the car has been fixed, please notify General Motors that, when I sell this vehicle, I will provide a ‘Lifetime Warranty’ on the vehicle’s security system (which is more than you can provide)
