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.

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

I changed my steering column but my past key turns everything on but it wont start the car do i need new ignition key


Yes, you need the correct resistor chip in the key for the PASS- key system to allow starting and the injectors to work. The computer will sense the correct resistance from the PASS- key and allow car to start.
PASS means Personal Auto Security System. Visit a locksmith who understands the PASS-key security system. Or the dealer. One of them should help you resolve it.

Security light comes on and car will not run. However when security light goes out car runs well. What is the problem?


you car is equipped with a pass key system, this year is most likely a pass key 2, but there is a small chance it is a pass key one, the pass key one has a pellet in the key ( a little black square in the shank of the key ) the pass key 2 has a resistor in in the ignition tumbler assembly ( that is the the key lock but it is called a key and tumbler assembly ) what is happening is the security system is not recognizing your key all the time in either case you will most likely have to replace the key and tumbler assembly, in order to do this you will need to have the system tested to know what the residence value is so you can get the proper key and tumbler set.

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.

Saturn LS1 2000 wants to start but won't


The fab key activates the security system in the car, the ignition pass lock may need to be reset to your ignition key's. It Takes about 30 min to do. Try resetting the pass lock to read your ignition keys. 30-Minute Learn Procedure 1. Turn ON the ignition, with the engine OFF. 2. Attempt to start the engine, then release the key to ON; the vehicle will not start. 3. Observe the SECURITY tell tale light. After approximately 10 minutes, the light will turn OFF. 4. Turn OFF the ignition switch, and wait 5 seconds. 5. Repeat steps 1 through 4 - two more times - for a total of 3 cycles of 10 minutes. 3x10 = 30 minutes. The vehicle is now ready to relearn the Passlock Sensor Data Code and/or passwords on the next ignition switch turn from OFF to CRANK. Important: Turn the Ignition Switch OFF. The vehicle learns the Passlock Sensor Data Code and/or password on the next ignition switch transition from OFF to CRANK. You must turn the ignition OFF before attempting to start the vehicle. 6. Start the engine. The vehicle has now learned the Passlock Sensor Data Code and/or password. 7. With a scan tool, clear any DTCs if needed. History DTCs will self clear after 100 ignition cycles. Without a scan tool you may have momentary starter interruptions while history clears itself. Good luck and hope this helps. The ignition keys has a resistor value for the ignition to read and after a few years the resistance may change and the Pass Lock has a had time reading it's value so you have to reset the pass lock to read the keys again.

Lost my last igniton key


15 different coded keys. these are resistor pellets . ranging in different ohm values if you got a key cut that will turn the cylinder, try google ( passkey ii bypass ) there is a listing of all the ohms radio shack and purchase all of them $30 give or take, get to the two small orange wires around the lock cylinder and cut them close to the lock intall the resistors one at a time in place of where the lock would be ,until you hit the one that lets it stay cranked. no more resistor key needed
