The leaving the key on the ignition works. It worked on my 2003 Malibu.
this is useful. Mine just locked yesterday with it running, and it tripped the system having to break in. I'm going to try it, this has
worked when i switched ignitions on my 00' grand am.
12/15/10 Had my car towed home last night because it wouldn't start - theft security light on, just wouldn't turn over. Have seen
this light on and off for a while. Did the "theft re-learn procedure" and the car started right up. Thank you so much!!!
would this basically be the same for a 95 Pontiac Firebird?
|These are two totally different systems. Yours uses a
chip in the key and the ignition cylinder to read it. See
this link for Passkey Theft System.
Wife car wouldn't start replaced passlock and Ignition cylinder haunt had any problem found out every time hit a bump or pot hole
it killed the car the car would crank but wouldn't start try waiting 10 min sometime work sometime didn't wiggle the key worked
some time and some didn't after replacing everything from start to fuel pump put in new pass lock and Ignition cylinder will take
care of the problems
i just replaced an ignition lock cylinder switch on my Chevy Astro v6 4.3 l now i have a security light flashing on it and wont star
can you help me any idea.
|You need to do a theft relearn procedure. Turn the
ignition switch from the OFF position to the CRANK
position, and then to the RUN position. The vehicle will
start and then stall. Leave the ignition ON until the security
telltale turns OFF in 10 minutes. Repeat steps 2 more
times. The Body Control Module will learn the new data on
the next cycle of the key from off to on.
I have a 2004 Chevy Classic that started having issues with the anti-theft light in April 2010. It went on about 5 months and finally
got to the point of me sitting in my car waiting 10 minutes EVERY time I put the key in the ignition to start it.I got frustrated and let
a place put a remote start in. It solved all my problems... For four months. Now when I start my car, as soon as i put my foot on the
brake the damn thing cuts off but still has power. Whenever it happens, if I try to use the key to start it the car won't even crank.
Last night it even shut down while I was driving on a busy street w my 3 kids in the car (luckily I was approaching a stoplight and
wasn't on the highway). It had been on with no issues for over 15 min. I am a single mother and I'm terrified to drive the only car I
have. Do you have any ideas as to how I should proceed? I know now that the autostart wasn't the cure, and it seems like the
ignition needs to be replaced all together.
|It does sound like possibly ignition switch problem. Not the
theft portion, which is in the key cylinder(Passlock Sensor),
but the switch.
I have a 97'Sunfire and when I start my car it automatically shuts down with the blinking theft lock light. It blinks 5 times then stays
solid. I left the car on for 10min, tried the relearn process doing it 3 times and the problem still happens again. Noticed comments
on other sites that the theft lock light is supposed to go away after the 10 minute wait but this does not happen on mine. Also
once the car starts I have no problem driving at all, took it to 3 mechanics all said nothing wrong with the parts... I'm confused...
THANK YOU VERY MUCH IT WORK VERY NICE.. I HAVE A 03 MALIBU THANK
YOU VERY MUCH
Thank you so much! The theft light was on and I couldn't start my car! But I did
what you said and it worked!!! 2004 Chevy Malibu!
if light is not on ......Will it still effect my car. My car starts and than stops right away
|If the theft / security light is not on when the car stalls, then
it is not a theft system problem.
someone mentioned this on another forum. They said to clean your keys with dawn detergent the use a compressed air can that
you use to blow out a computer keyboard blowing it into the ignition. This apparently is to help clean the ignition and passlock
sensor. Do the procedure of waiting 10 minutes of the key in the off position until the security light quits blinking then turn key to
the off position to reset and restart. Apparently the reasoning is that over time lint and dirt over time compile in the ignition switch
and sensor making it hard to recognize the key. Have done on my car and so far so good. Not positive, but I do think the car is
firing and starting quicker with less cranking. Likely recognizing the key better
|I 1st experienced this on my 2004 Chevy Malibu last fall in 2010 and I had it towed.
Through trial and error I discovered that it was my theft system. Fast forward to
Feb 2011 the car is beginning to do it more often.I personally think it should be a
recall on this problem and the Chevy Corp should be responsible for repairing this
|You advice has been very helpful. My mother just gave us her 1999 Malibu that is in very good condition except for this annoying
problem. She had the ignition switch replaced after her warning lights started coming on and her door locks would go up and
down on their own. Since we have had the car the warning lights seem to go through a cycle at random periods, first the battery
light will come on then after maybe 5 minutes it will go off, then the air-bag light will come on for a minute and go off but the car will
begin to shift really hard after that one and we have to stop, turn it off, then back on and it corrects the problem. Sometimes the
ABS light kicks on with the airbag light. Last week it died on me twice when the theft system light came on. The first time I parked
immediately and turned off the car and it would not turn back on. The radio and all would turn on but not the car. My husband
had to come and jump start it !
And it started. It was fine for the rest of the day. Then I drove it about 2 hours and the theft system light came on again while on
a highway at night, I did not stop this time, but lost my head lights, radio, all of my accessories and made it to my street just before
it died. That was about 25 minutes after the theft system light came on. It has been about a week and has not happened again.
Does this also sound like the ignition cylinder?
|No, not a recall. Read all the above post and all the
thousands of other articles on this subject all over the web.
|My 1999 malibu has an after market anti theft thingamabob and it has a tiny switch
that some how decided to get switched off so thank you people for all your cool
|I bought my 1999 Chevy Malibu from Car Max and immediately started having problems with it not starting (anti-theft light blinking)
so they replaced the key thinking this was the problem. Worked for about a month, then started happening again. They could
not find anything wrong with it when they put it on their machine. Fast forward and now my car is no longer carried under
warranty and to fix it would have cost over $800. As far as I'm concerned they should still cover this problem. Is this a RECALL
problem on Chevy Malibu? I had a friend replace the sensor and that worked for while, but now it's doing the same thing which
makes me think it is a recall problem!!!!
|have had problems with my 2004 malibu in the anti theft system ordered a unit to
do away with the system no more problems 179.00 for the unit well worth it.
|Thanks to your posting I was able to fix my wife's car that lost it's code Mother's
day morning.(maybe now i don't have to buy flowers?)
Thank you so much
|i have the same problem (theft security system)and engine will not start
is the process described in the theft relearn procedure the same for a 2000
|My car had problems starting then he disconnected th battery. The problem is that
his car starts but the security light is still on and he has no radio or air
conditioning. He car runs great except for the security problem. Any suggestions?
|I think you have a couple different problems going on there. The security light problem can be caused by a
bad ignition cylinder, which includes the passlock sensor. The body control module controls the theft
functions through the ignition, and it could be faulty as well. Either of these, if replaced would need to be
programmed by a dealership. The radio could be inoperative due to a blown fuse, or by disconnecting the
battery you could have activated the theft system on the radio which would need be to reset. You can find
more information about radio codes on our website. The air not working, could be a bad control head, or
even a blown fuse for that.
|Theft system light flashes car wont start....now the light stays on most of the time.
|I just inquired about how much the ignition switch and cylinder cost, and to my
surprise it was a total of $458. That only for the parts not the service, all together
the tech said it would be from $600 to $700!!! Ouch, GM should have this as a
recall dam it.
|The advice about the Theft Light was very helpful. At exactly 10 minutes, my light
shut off; then I was able to restart my car.
|This is a defective component issue with the GM cars in
question. GM knows it and doesn't care. Every time it
happens, count on spending $500 to $600.
