V6-191 3.1L Key security code

Hi, son lost keys for good. We have replace ignition, have been instructed how to by pass the code. Using resistors, told GM has 12 or 15 variations. Have used everysingle one with resistor kit. I read somewhere that the VATS wire was on the passenger side of the 91 and was a green wire. Parts store is saying is a orange wire and that is not working when splicing in the resistors. Any one know any other way to by pass this code? Thanks.

Security fuse 1999 pontiac bonneville


Need a little more info . Security fuse ????? Do you mean anti-theft ? The SECURITY light is lit on the instrument cluster ? Content theft or vehicle theft ?
Vehicle Theft Deterrent (VTD) Description
Ignition Key
The ignition key for vehicles which are equipped with the PASS-Key® II system consists of the following components:
• A typical square ignition key blank
• A resistor pellet
The PASS-Key® II ignition key has the same mechanical key cuts as a non-PASS-Key® II ignition key. You can not service the key blank and resistor pellet separately. There are 15 different ignition key assemblies, each with a different key pellet resistance value.
When you service the PASS-Key® II system, obtain all ignition keys. Verify the proper key code values withJ 35628-A Interrogator.
Steering Column (Ignition) Lock Cylinder
The steering column (ignition) lock cylinder that is used with the PASS-Key® II system contains a set of electrical terminals. The terminals are used to contact the resistor in the ignition key.
The wire routing for the contacts inside the steering column is very critical. When you service the lock cylinder, maintain proper wire routing.
When you replace a steering column lock cylinder, make new keys. The new keys must match the following items:
• The PASS-Key® II code of the PASS-Key® II system
• The mechanical cut of the new steering column (ignition) lock cylinder.


Measure the resistance of the pellet on the key , go to radio shack an buy a resistor of same value an solder into wiring harness .

pulling fuse won't work , power's the PCM as well . Plus software in the PCM won't let it start if it doesn't see input signal from the Theft deterrent module .Take an get it fix right .

1998 s-10 security light


If the security light is hot or flashing when the key is in the on position, most likely the ignition key tumbler housing has failed.

You can try resetting the pass code by turning the ignition switch to the on position (do not crank or start the engine). Leave the key in the on position for 10 minutes. Turn the key to the off position, wait 5 seconds and turn the key to the on position again and leave it on for 10 more minutes. Cycle the key to the off position again for 5 seconds the back on for a final 10 minutes. Once the final 10 minutes is complete, turn to the off position again, wait 5 seconds and now turn the ignition on and to the start position. The pass code has now been reset and it should start. If the reset does not work you will have to change the ignition key tumbler housing that contains the key code resistor.
Good luck

97 Monte Carlo security system


The theft deterrent module probably isn't energizing the theft deterrent relay . Most of the problems with this anti-theft system is that the contacts inside the ignition key lock cylinder wear out an can't read the resistor pellet on the key or the wires on the back of the key lock cylinder break . This all mean the key lock cylinder probably needs to be replaced .Or you can do a by pass !

1999 Buick Century Custom Security light blinks and car will not start


someone told me to by getting out of the car and locking the driver door with the key, going to the front passenger door and unlocking, then relocking the door using the key. I have to repeat this step 2-4 times and eventually it will start. ?????????
This has nothing to do with it starting !

This is what's happening , Inside the lock cylinder are contacts that read the resistance of the pellet on the key , the contacts are getting worn out . You have two options , replace the lock cylinder or by-pass it all together .
The PASS-Key II® ignition key (1) contains a unique resistor pellet which is idenified by the Body Control Module (BCM) (2). There are 15 different key (resistor) codes. Only one ignition key resistor pellet code will work with each PASS-Key II® theft deterrent system.
Ignition Key Lock Cylinder
The ignition lock cylinder contains spring loaded contacts which make physical contact with the ignition key when it is inserted into the ignition lock cylinder. This allows the ignition lock cylinder to provide the Body Control Module (BCM) (2) with the resistor code embedded in the ignition key.

Have it checked for DTC'S - diagnostic trouble code's . I suspect the problem is with the tdm module or the ignition switch ???? Assuming will only get you into trouble . If the PCM - engine computer does not see the right coded meassage from the TDM it won't turn on the fuel injectors or it will cut them off in two seconds . .

Ignition Key With Wrong Resistor Pellet Code is Used To Start Engine
The theft deterrent module performs one of the two following actions when you attempt to start the vehicle with a wrong ignition key:
• There are 15 PASS-Key® II resistance ranges. The PASS-Key® II resistance may be one of the 14 valid but incorrect PASS-Key® II resistance ranges. The theft deterrent module will perform the following actions when you attempt to start the vehicle (if the condition is present during an engine start attempt or for 1 second any time after the engine has started):
• Turns on the SECURITY indicator
• Sends a password to the PCM through the fuel enable signal circuit
• The password disables fuel delivery to the engine.
• Disables the theft deterrent relay, which disables the starter circuit
• Disables sampling of the PASS-Key® II resistance for 3 minutes
• The 3 minute time period is called the shut-down period.
• Disconnecting the battery will not clear the timer sequence. The timer sequence will resume when battery power is restored.
• Inserting the proper key during the vehicle shut-down period will not start the engine. The engine will not start until the shut-down period has elapsed.
• After the shut-down period, the engine will start if the correct ignition key resistor pellet is used.
• The PASS-Key® II resistance may be correct and allow the engine to start. Later during the same ignition cycle, the PASS-Key® II resistance may be one of the 14 valid but incorrect resistance ranges. The theft deterrent module will perform the following actions:
• Enters the fail-enable mode
• Turns ON the SECURITY indicator
• Sends a password to the PCM through the fuel enable signal circuit when more attempts to start the engine occur
• The password allows the fuel enable circuit to deliver fuel to the engine.
• Enables the theft deterrent relay, which also enables the starter circuit.

Ignition Key With Correct Resistor Pellet Code is Used To Start Engine
The theft deterrent module performs the following actions when the correct ignition key is used in order to start the vehicle:
• Enables the theft deterrent relay. The theft deterrent relay enables the starter unit.
• Sends a password to the Powertrain Control Module (PCM) through the fuel enable signal circuit. As a result, the PCM allows fuel delivery to the engine.

Security button to resetm pass key is located where?


your vehicle is equipped with Personal Automotive Security System (PASS-Key II(R)).
This security system is designed to prevent vehicle theft by disabling fuel system and starter unless an ignition key with a specific electrical resistance is used in the ignition key lock cylinder. PASS-Key II(R) system operates using sensing contacts, which are located in the ignition key lock cylinder. These contact a resistor pellet located in the ignition key. When lock is rotated, battery voltage is applied through appropriate fuse and resistor pellet to theft deterrent module (except Century), or body control module (Century). Pellet resistance is then compared with programmed value in the theft deterrent module or Body Control Module (BCM).
System components include ignition key, ignition key lock cylinder, theft deterrent module (except Century) or BCM (Century), theft deterrent relay and Powertrain Control Module (PCM). The PASS-Key II(R) system can also be supplied as a special equipment option on some vehicles

It will reset itself after about 10 minutes. You just have to wait until you hear a click and the pass key light goes off.
Be sure to clean the little metal strip on your key while you're waiting...

In my 2000 chevy camaro my security light is on and my car wont start what process do i need to do to get it running?


Your vehicle is equipped with the PASS-Key II (Personalized Automotive Security System) theft-deterrent system.
PASS-Key II is a passive theft-deterrent system. It works when you insert or remove the key from the ignition.
PASS-Key II uses a resistor pellet in the ignition key that matches a decoder in your vehicle. When the PASS-Key II system senses that someone is using the wrong key, it shuts down the vehicle's starter and fuel systems. For about three minutes, the starter won't
work and fuel won't go to the engine. If someone tries to start your vehicle again or uses another key during this time, the vehicle will not start. This discourages someone from randomly trying different keys with different resistor pellets in an attempt to make a match.

The ignition key must be clean and dry before it's inserted in the ignition or the engine may not start. If the engine does not start and the SECURITY light stays on when you try to start the vehicle, the key may be dirty or wet. Turn the ignition off.

Clean and dry the key. Wait about three minutes and try again. The SECURITY light may remain on during this time. If the starter still won't work, and the key appears to be clean and dry, wait about three minutes and try another ignition key. At this time, you may also want to check the fuses (see "Fuses and Circuit Breakers" in the Index). If the starter won't work with the other key, your vehicle needs service. If your vehicle does start, the first ignition key may be faulty. See your dealer or a locksmith who can service the PASS-Key II.

If you accidentally use a key that has a damaged or missing resistor pellet, the starter won't work. The SECURITY light will flash. But you don't have to wait three minutes before trying another ignition key.

See your dealer or a locksmith who can service the PASS-Key II to have a new key made.

If you're ever driving and the SECURITY light comes on and stays on, you will be able to restart your engine if you turn it off. Your PASS-Key II system, however, is not working properly and must be serviced by your dealer. Your vehicle is not protected by the PASS-Key II system. If you lose or damage a PASS-Key II ignition key, see your dealer or a locksmith who can service PASS-Key II to have a new key made. In an emergency, call the Chevrolet Roadside Assistance Center at 1-800-CHEV-USA or 1-800-243-8872 (In Canada call 1-800-268-6800).

The security light is blinking and when you try to start it there is nothing, new battery,starter, it simply is not getting power to start it..It seems like it is a security lock out.. dont know where to...


Normally, you would insert the key in the drivers door, turn left, then right to disarm and reset it. If yours is malfunctioning, you can disable it for good by doing the following:

The FACTORY ALARM DISARM WIRE IS
light green with a negative polarity at the harness coming out of the door in the driver's side kick panel.

Once Located, splice into this wire with a similar guage wire, and put it to a solid chassis ground. This terminates the OEM alarm functions entirely.

OR:

Bulb Stays Illuminated and Engine Does Not Start. If the "SECURITY" indicator stays illuminated while and after attempting to start the engine and the engine does not crank or start, this indicates that the PASS-Key II module has sensed an improper key value and has disabled the engine and set the disable timer. This specifically does not mean that the key sense circuit is open or shorted to chassis ground, refer to "Bulb Flashes and Engine Does Not Start." Remove the key from the ignition and verify that is the correct key code for the vehicle. The key code may be checked using J 35628-A and comparing the key code to that of other keys for the vehicle. After waiting approximately 3 minutes for the disable time to expire and the "SECURITY" indicator to go out, try to start the engine with a known good key with the proper key code.


Bulb Flashes and Engine Does Not Start. If the "SECURITY" indicator flashes once per second and the engine does not start, this indicates that the PASS-Key II module sensed an open, a short or otherwise invalid (value matched none of the available 15 key codes) input from the ignition key resistor input. The PASS-Key II module does not start the disable timer during this operation mode. This operation mode could also be caused by a malfunctioning power or ground circuits.

OR:

There is 2 more ways to fix the problem:

1) replace key cylinder (very difficult)

2) look for 2 small white wires encased in an orange cover at the bottom of the steering column at the big steering column connector. Cut the two small white wires and connect a resistor of the same resistance of your key chip onto the two white wires leading into the connector. Problem solved!

If you do not have a pass key any more, then you will need to dissable the antitheft (pass key module) in order for the engine to turn over. From what I gather you have replaced the column with an older version, which will not allow any comm. with the module. The pass key module enables the starter circuit. See diagram.
