The thing that causes the PASSLOCK to activate is the chip, if you will. If the chip is bad, ar is unrecognizable to the system, the PASSLOCK will activate. Take it to a dealer asap.

You can bypass the passlock by accessing the ignition, and cutting the yellow wire of a small 3 piece wire set that's on top of the ignition.

cut the yellow small wire from ign. switch in the column up by the switch. this is the passlock wire.

Where is ignition module on 2002 impala?

The ignition module on a 2002 Impala is located in part of the electrical system. In some cars, the module kept the car from starting. When the key was turned there would not be a clicking noise. The module works with the passlock system of the car.

On 93 Grand Am what could cause the crank sensor and ignition module go out when you replace your starter and ignition switch-entire steering wheel?

so you replaced your entire steering wheel and switch and that did not work and was told you needed a starter. The starter was replaced and that did not work. Now it is the crank sensor and ignition module. Not sure of the symptoms, you were not spacific.... Maybe you just need to reprogram the Passlock Anti-theft system to recognize the new key. If you attempt to start the vehicle with a key that it does not recognize it will start for a second and then die, the injectors are disabled by the system. If the car turns over and does not start, I would guess that this is your problem since you changed out the ignition switch. Research the Passlock system. I am guessing you need to do a reprogram.

Can using same car key for years make security light and service engine light come on in 02 impala after putting new battery in?

Your vehicle has the PassLock system, not the older PassKey. In the PassKey system there was a resistor pellet in the key that would go bad. In PassLock, the guts of the system are behind the lock cylinder. PassLock has almost a 100% failure rate and the way to fix it is to replace the lock cylinder assembly. I've attached a post link that describes what you need.

How do you fix a flooded engine on a Pontiac Grand Am?

Let it set it should start. If not your vehicle is equiped with an anti-theft system, it may be malfunctioning. The Passlock Anti-Theft on all GM vehicles will disable the fuel injectors if it thinks the vehicle is being stolen. This could hapen if you changed keys or the sensor in the ignition cylinder is bad. This would give you the same effect as if the vehicle was flooded. It might start for a few seconds, then die. Try the reset method below. Reset Method or the Passlock 2 system, put the key in the ignition and turn the engine over (the car should not start, if it did you are done), turn the key to the ON position, let it set for 10 fmin. The security light should be flashing. After 10 min. the security light should stop flashing the car is ready to learn the new key value. Turn the key off, wait 5 seconds, and then try to start the car.

2004 Chevy Malibu sometimes will not start Anti theft light is also on Only way to start is to reset Any suggestions?

The anti-theft feature prevents the car from being started when one of several anti-theft devices is faulty are have otherwise been activated. The problem you describe might be the ignition switch, which is known to wear out quickly on those models. The system can be completely disabled only when the car is running (meaning the theft deterrent system is inactive after the Passlock II system detects the proper key in the ignition). A wire can be cut that would permanantly disable Passlock II, meaning any key that opens the door (or a screwdriver) could start the car. If the ignition swtich goes out or this wire is cut while the engine is off (theft deterrent system is active) then the car will have to be towed back to the dealer to have the ignition system replaced and reprogrammed.

Would a bad ignition module cause a car to stall and not restart?

yes once the ignition control module heats up it would cause the vehicle to stall. usually after it cools down the vehicle will restart again.

How do you reset passlock for 2001 Chevrolet Impala?

There are a myriad of possible "solutions" available. If you are even just a little bit technically savvy you can with a little bit of effort disable and or bypass the "passlock" system. Just Google Chevy impala passlock disablement or Chevy impala passlock bypass. There are several ways to do this and it would be better for you to read all the information available and arrive at your own decision. This seems to be a "VERY PREVELENT PROBLEM"

Why would myChevy cavalier has no spark and or fire the theft system light is on have changed everything?

That's their "passlock' system, it cuts off fuel to the engine. I think it's activated by the car being turned on w/o a key in the ignition. I'm not too sure that replacing everythng will solve your problem. ask the dealership I guess, unless someone else knows? That's their "passlock' system, it cuts off fuel to the engine.

Will trying to insert the door key into the ignition ruin the ignition if the ignition key has a chip?

Well, I don't see that it would help it any! There are 2 keys for a reason! Why would you want to insert the door key in the ignition? It surely won't start the vehicle! Unless the ignition is already screwed up and can start with anything! The tumblers in the the locks for the ignition and doors are different! It would be like putting your house key in the car! Won't work!

Can a malfunction in the fuel pump cause a malfunction in the theft system?

If you have a VATS (vehicle anti theft system) equipped vehicle, it would be the other way around....The theft system would cause the fuel pump malfunction. If the theft system does not detect the correct value of the chip in the key it will prevent the fuel pump from functioning. Depending on the year and type of system, (VATS vs. Transponder) your VATS pellet may be worn out and the ignition is unable to read the resistor value. If it is Transponder equipped you may have a faulty chip antenna.

PASSLOCK I or II DISABLEMENTThe following is a procedure to disable Passlock I or II Systems for vehicles in which remote start/stop system installations are required. This procedure is required because a remote start system will not function with the current Theft Deterrent System (Passlock) which is included on many 1996 and up GM vehicles.Please note that this modification is intended to be used only in conjunction with the installation of a remote start/stop system and does not provide a procedure to install a remote start/stop system.CAUSE If an attempt is made to start a vehicle by a means other than a key rotation in the ignition switch, the Body Control Module (BCM) will interpret this start as a vehicle theft and disable the fuel injectors.CORRECTION A minor wiring modification may be made to allow the vehicle to be started remotely. This modification includes adding a switch to allow the customer to select �ON� to disable Passlock or �OFF� for normal Passlock operation.CAUTION: When this modification is performed and the switch is set to the ON position, the theft deterrent feature will be disabled. When the theft deterrent is disabled the SECURITY or THEFT telltale will light up indicating that the theft deterrent system is NOT functioning.PASSLOCK MODIFICATIONRefer to appropriate GM service manuals and/or SVMQP Electrical Guideline Manual for instruction on splicing and electrical connections. 1. Select a suitable on-off switch (see note below) which will be used to disable/ enable the Passlock System. Mount the switch in a location such that it is accessible to the driver and will not interfere with normal vehicle operation. NOTE: This is an extremely low current circuit (approx. 7mA), it is therefore very important that a high quality, low energy, fast acting switch be utilized for this application. 2. Turn the ignition switch to the OFF position. 3. Locate the Main Ignition Switch Harness. GM's Passlock System wires exit the Ignition Switch Tumbler together and then join with the Main Ignition Switch Harness. (See or and select your Make, Model and Year for wire colors and clues on the quickest way to access these wires.) 4. Locate the Yellow Passlock Data Wire which is included in a bundle of three tiny (20 GA) wires wrapped in friction tape. Cut this wire and splice a 0.5mm2 (20 GA) yellow wire to each end of the cut wire. Keep wire length to a minimum. Route modification wires clear of moving parts. Connect the yellow wires to the switch such that the contacts are OPEN when the switch is in the ON position. 5. Turn modification switch to the OFF postion (contacts closed). 6. Start vehicle to verify normal operation. If engine �cranks but will not start" recheck the switch position (contacts should be closed), wire connectors and modification wiring.SWITCH OPERATIONTo enable remote start: Start the engine with the ignition key (modification switch must be in the OFF position). Turn modification switch to the ON position (contacts open). The SECURITY or THEFT telltale will light up indicating that the Passlock System is inoperative. Once the SECURITY or THEFT telltale has been on for at least 5 seconds the vehicle can be turned off and then remotely started.To disable remote start: The Passlock System can be reactivated by turning the modification switch OFF (contacts closed). Vehicle can either be running or off when this is done.Please note that the VCM/PCM will record Diagnostic Trouble Codes (DTCs) related to the security system when the modification switch is in the ON position (circuit open). This is due to the way that the VCM/PCM interprets this condition.NOTICE Any condition which removes battery power from the Vehicle Control Module/Powertrain Control Module (VCM/PCM) (e.g. dead battery, disconnected harness connectors, etc.) will prevent the vehicle from being restarted. If the engine exhibits a �cranks but will not start� symptom, place the modification switch in the OFF (contacts closed) position. This will reactivate the Passlock System and allow the vehicle to be started with the ignition key.This really works, took me about 45 min's and a cost of $4.50 for the switch "that had short wires built in"! Wish I would have known this before all the headache, and $$ spent...GM kept tell my mencanic it can't be done...BULL!!!!AnswerYou have a passlock security system. I had mime replaces @ $300 and now 85 days later it is doing the same thing! The fuel pump is shutiing down because the security system is telling the car that someone is trying to seal the car-This is the first year that the system can not be bypassed-before 1997 you could just bypass it some way. Be sure that you NEVER try and start the car until the light stops blinking. Otherwise the 10 min has to satrt again GOOD LUCK!! if you simply cut the small yellow wire in the column from the ignition switch it will disable the passlock system and the carwill start and run fine. the security light in the dash will always be lit up solid. worked great on our 1998 after we sent in the IPC twice to be repaired. and also replace the lock cylinder and chip key to try to solve no start problems with the passlock system.. also to no avail. car has been startign perfectly for over a year now after cutting the yellow wire. there are three small wires from the ignition lock assembly. the yellow one is the one to cut. i am going to today install a remote start kit on a 1991 and will cut the same wire to disable the passlock system on it so the remote starter will work.Listen to these people!! They know what they are talking about. I followed their advice cause i was having the same problems with my 97 achieva. I cut the yellow wire and had no trouble since. the security light on the dash blinks all the time but its worth it to me! Good luck!!UPDATE 01/16/2010: I have a '97 Olds Achieva as described and experienced exactly the same symptoms--crank, no start. I went down to Pep Boys and purchased a two-way toggle ($2.99), some wire ($5.99) and went to work as described above. I cut the yellow wire in the three-wire set, spliced it into the toggle, tape it all up with some electrical tape and the car started right up! I put everything back together gently, leaving the toggle hidden in the column shroud, tested it some more without problems, and here I am, having saved myself countless dollars and hours of frustration! Follow these instructions and you can't go wrong! Email me if you run into the same problem and I'll walk you through it: have a 1998 Oldsmobile Achieva SL with the same problem, the security light comes on and when i try to start it it cranks but turns off immediately after start up. Many people and many different sites have recommended cutting the yellow wire in the steering column to bypass the security system but when i did so the engine continues to turn off immediately after start up. I know there's no problem with the engine or fuel pump because just the day before when i left the key in the ignition for ten minutes and waited for the security system to turn off it worked just fine. Any ideas or suggestions?

Is there a fuel system shutoff and reset on a 2001 Grand Am?

I have a 2001 and it does have a fuel shut off, but only activates when the passlock system is activated. If it seems to happen intermittently, have a new key made. My old keys and lock cylinder were worn out and causing the anti-theft system to engage. If you go through the 10-minute reset procedure (in your manual) it will start. I had a new key made (not cut from an existing key) and the problem has not happened again in over 6 months. Eventually I am told you would need a new ignition cylinder, but this is a cheaper temporary solution.In short, the only fuel shut-off is the pass-lock fuel pump disabler.Hope that helps.AnswerI have a 2000 Pontiac Grandam with the famous Ass-Lock system installed, had the same problem, very frustrating.Your anti-theft passlock system senses the RESISTANCE value across your ignition cylinder when your key is in it, over time your key will 'wear' the inside of your ignition cylinder and itself thus changing the 'R' ( resistance value ) to the trigger threshold and causing intermittent ' fuel shutoff ' problems due to Passlock. A new Key and ignition coil will fix the problem, OR there is an easy workaround.From inside the car, pull the center panel-shroud off, this is the plastic housing surrounding the stereo and climate controls, it is just clipped on and easily removed, once off you will be able to see and access the wire bundle coming off the rear of your ignition cylinder,you may need to remove some of the black insulating wrap to reveal the wires. You are looking for the only yellow wire, this is the ' R ' ( resistance sensing ) lead for your passlock, with the ignition turned on, cut this wire, the Passlock will assume sensor failure, illuminate the SECURITY light in your dash and bypass the fuel-shut-off portion of the protection system. If you wish you can remote a switch by addig about 5 bux worth of extra wire and a switch between the now cut ends of the yellow 'R' lead and routing the remote switch under the dash, this allows you to re-enable your passlock fuel bypass security system at your leisure.The only disadvantage to this workaround is the constant illumination of the SECURITY light, however your central locking and all other features remain fully functional and hey you won't have to spend another 10 minutes beating your dash waiting on the system to reset. Good Luck !

How can you tell if a starting problem is a starter or an ignition switch or a clutch switch in a 94 Honda Accord with manual transmission?

if you turn your key and nothing happens just the dashboard lights come on that would be your clutch start switch. if you hear a grinding sound when trying to start vehicle or a humming sound that would be your starter.if the vehicle cranks fine but for some reason it won't start then you would look at the ignition system(spark plugs,wires,etc) as your first possible cause.

1999 Pontiac sunfire you need a diagram of the steering column and ignition switch your car will not start Is there a Kill switch It turns over but will not stay on it just shuts off?

there are three wires that come off the ignition switch cylinder the must clip tightly to the wires that run down to the ignition switch. on my car i replaced the ignition switch cylinder forgot about the wires and the same thing happend it kept dieinguntill the wires were securly/tightly connected. I don' think I would just start hacking at wires. A wiring diagram if available would do little good. I really doubt you have a wiring problem, it is more than likely a problem with the Passlock Security System (factory anti-theft system). I have done a lot of looking into this system in the past week, it is really quite simple, yet sophisticated. Have you changed keys or had new keys made lately? If you have, you may need to go back to using the previous key or do a reprogram of the system to teach it the resistance value for the key you are using. If that does not work, more than likely it is the device in the ignition cylinder lock is bad. The device in the lock reads the resistance value from the key and tells the computer that the correct key is being used to start the vehicle. Try this process: For the Passlock 2 system, put the key in the ignition and turn the engine over (the car should not start, if it did you are done), turn the key to the ON position, let it set for 10 min. The security light should be flashing. After 10 min. the security light should stop flashing the car is ready to learn the new key value. Turn the key off, wait 5 seconds, and then try to start the car.

What is going on when your security light for a 1997 olds achieva stays on and car won't start?

Oldsmobile Passlock Security SystemFrom the Oldsmobile Achieva owner's manual: Passlock (TM)Your vehicle is equipped with the Passlock theft-deterrent system.Passlock is a passive theft-deterrent system. The system is armed once the key is removed from the ignition. Passlock enables fuel if the ignition lock cylinder is turned with a valid key. If a correct key is not used, fuel is disabled.During normal operation, the SECURITY light will go off after the engine is started. If the engine stalls and the SECURITY light flashes, wait until the light stops flashing before trying to restart the engine. Remember to release the key from the START position as soon as the engine starts. If you are driving and the SECURITY lights comes on, you will be able to restart the engine if you turn the engine off. However, your Passlock system is not working properly and must be serviced by your retailer. Your vehicle is not protected by Passlock at this time. You may also want to check the fuse or circuit breaker. See your Oldsmobile retailer for service.If the SECURITY light comes on while the engine is running, a problem has been detected and the system may need service. See your dealer for service.Note: my Achieva has a 'bypass' switch located in plain sight on the lower side of the dash near the hood release latch. I have had to push that button while trying to start the car. I did not have the remote on that key chain. If you have a remote, make sure the batteries are fresh and try to resynchronize the remote to the vehicle following this procedure:SynchronizationYour Remote Lock Control system is equipped with a security system that prevents anyone from recording and playing back your signal. The transmitter does not send the same signal twice to the receiver. The receiver will not respond to a signal that has been sent to it more than once. To resynchronize your transmitter and receiver, follow these directions:1. Stand close to your vehicle2. Press and hold the LOCK and UNLOCK buttons on the transmitter at the same time.3. Hold the buttons for five seconds. In this time, the doors should lock and unlock once. This confirms the resynchronization. If the doors do not lock and unlock, see you retailer for service.why don't you do just what i did? disable the security! nobodys going to steal an achieva anyway unless they are crazy then they would probably bring it back! lol take off the cover to the steering column. look on the passengers side of the column and you will see 3 small 20 gauge wires, yellow, white, and black. cut the yellow wire. problem solved! security is now disabled. your security light on the dash will stay on all the time now when running but isn't that better than paying hunderds of dollars for maybe nothing? I know this works cause i had to do it on my 97 achieva. Good luck

How does the ignition system start up the engine?

There were only a few cars in history the "Ignition System" started the car. For Example: The Rolls Royce cars in the early 20 th century had a system that allowed you to quickly advance the ignition lever and the car would start. In modern cars The ignition system starts to make a spark at exactly the right moment when the starter rolls the engine over. The terminoligy we use for how we start cars is due to the use of the Ignition Switch to also control the starter.
