Car not starting - security issue?

When I put the original key in the ignition, car turns over, but just won't catch and stay started. Acts exactly the same way as then the fuel pump has gone. Mechanic said the security light was on (but it was not for me at anytime in the past couple days - nor when it wouldn't start). He advised there were two security lock codes appearing when he ran the diagnostic. He cleared them and the car started. The security light has been on a few times (under 10 for sure) with no rhyme or reason over the past couple years since I first got the car. This is the first time the car has failed to start due to security reasons. The mechanic could not explain why it was an issue now and not any of the other times. And could only say that maybe the car was attempted to be broken into - that if the problem persisted, he would look further into it. My question: is there anyway for me to clear the security lock code on my own - without the expense of getting it towed to a garage? This could become very costly and expensive! Is there anyway to disable it altogether? Any suggestions would be most appreciated.

Two possablites, one for some reason the someone entered through the passengerside started the car before opening the driverside door, this will throw the code, the other is raising the front or rear of car off the ground past 7 or 8 digrees as if beeing towed by a tow truck . without key in ignition

Testimonial: "This solution explained it much better than the garage attempted to. Now I know how to possibly prevent this from happening again."

You are discribing an issue with the PASSLOCK II factory security system, would like to know what the components were that the codes represented, most likely the key code receiver is acting up and causing the problem

Testimonial: "It was somewhat helpful. The garage did not provide me with the actual codes that were cleared, so I cannot get a possible solution."

That is a know issue with that model car.
If I remember correctly you have to put the key in the ignition and turn the car on (Don't Start it) Just leave it On for about 10 min. the light should go out . Then turn it off and then start the car.
Hope that Helps.

94 Toyota Camry ignition lock cylinder issues

The problem of the car dying should be unrelated to the worn key and ignition barrel, as the electrical contacts only depend on the key turning, which it does.

The car may have -

- a vacuum leak somewhere in the intake tract. Look for a split in the big flexible coupling after the air cleaner

- insuffiicient fuel pressure. This might be a blocked filter, pinched fuel line (from a rock), failing pump, or a faulty overpressure release valve in the fuel rail. Get a fuel pressure gauge connected to the fuel rail and see what it reads.

My 2005 chevy impala won't start since someone broke into my car

i would say when the person broke into your car they set off the security system which stops the car from starting, the way to reset the security is to put your key into the ignition turn the key until all the dash lights come on and let them stay on about 15 minutes after the 15 minutes have expired turn the key off and wait about 3 seconds and then your car should start. hope this helps.

1996 Oldsmobile Achieva: Security light flashes upon startup

Here is what you do, but only when the SECURITY light flashes - if it is always ON or OFF it's no use.
Turn the key in the ignition to ON.
Wait for exactly 10 minutes ( SECURITY light will flash for 10 minutes and then stay on SOLID)
Turn the key to OFF
Wait 5 seconds.
Turn the key in the ignition to ON.
Wait for exactly 10 minutes.
Turn the key to OFF
Wait 5 seconds.
Turn the key in the ignition to ON.
Wait for exactly 10 minutes.
Turn the ignition OFF.

Start the car normally.
It has relearnt the keycode and you're good to go.
NOTICE - it takes 30 minutes to relearn, that's THREE cycles of ON - 10 minutes - OFF.

Good luck.

Aztek won't start,key locked in ignition, service engine light on

It is the security chips in the keys. Has this car been wrecked? Was this car made in Mexico? GM had the bright Idea of creating a security system that would do exactly this, I know on cars made in Mexico (like the HHR) You can reset the power and get the key back out, but vehicle will have to be reprogrammed with the master key. This involves turning the key from off to run position without ever going past run (i.e. start position) leave key in this position for 30 minutes. Turn key back to off for 30 seconds then back to run for 30 minutes. repeat this step three times. the last time, after 3rd 30 minute period, turn key off for 30 seconds and then try to crank. Please note this only works if the original master key is being used. You can then reprogram the second key following a similar sequence, only master key that is working has to be inserted to let alarm system know that vehicle is not being stolen only that you are trying to reprogram a key. If original master key is not being used then vehicle has to be taken to the GM dealership to program keys and possible key module replacement.

Security light stays on, and car won't start.

leave key in "ON" position (not start) for EXACTLY 10 MINUTES! As SOON as the light shuts off, turn key and start key.

Every time you put key in, turn and start right away, DO NOT HESITATE.

There is a problem with the car's computer causing this problem IN ALL GM VEHICLES.
