Why does the anti theft system keep tripping on my 03 malibu

Asked by Feb 23, 2011 at 12:19 AM about the 2003 Chevrolet Malibu Base

Question type: Maintenance & Repair

Every other day my anti-theft system goes off in my car then I have to reset it. It's not hard, but it is a pain in the butt. Why is this happening?

This is a common problem with older model (hopefully not newer model) malibus. Google "problems w malibu theft system". Wait 10 minutes until the light stops flashing, then start. Repairs could run from hundreds to over a thousand dollars. Could be a bad key, computer or ignition assembly. Try the less used spare key which should be straight and not worn too much. The system should read it better. Start car with your foot over the gas pedal rather than the brake, then gun the engine. You may have to keep the key in the start position a little longer than usual for it to start. In the long run you may have to repair the problem as it may get worse and compromise your safety even more.

I have the same car, with the same damn problem. Someone recommended this to me because it 'resets' the system. It is recommended to do it 3 times which will take up to half an hour. My vehicle usually recognizes the key about a minute after it's set to ACCESSORY. 1. Put the key to accessory and wait until the dash lights up 2. Turn the car off without starting it 3. Turn they key again (repeat step 1) then start it up in a smooth motion 4. Repeat #3 5. Repeat #3 I have not tried this yet because that theft system is a hit or miss. It usually likes doing it when I am leaving work! A few people have told me it's worked. Maybe the THEFT SYSTEM will go off when I am driving down the road!! It hasn't done anything though, the light just stays lit.

All these cars with problems and when I called Chevy & GM they act like they never heard of this & the price they tell you to fix it which is not guaranteed are crazy.

I called GM today (09/17/14) and they acted like they'd not heard of this problem - told me that it's not related to the ignition switch recall because this doesn't happen when the car is already running/in motion. Just to 'diagnose' the problem at my local dealer is $115.00 - that doesn't include any parts or labor (and doesn't guarantee that the issue will go away!). I'm thinking that somehow it is related to the recall and they (GM) just doesn't want to 'deal' with it. I have been stranded a few times now with this issue - I can't afford to fix this issue for now so I guess I'll just keep hoping that the 'tried and true' method of putting the key in the ignition for a little while and trying to reset the anti-theft system keeps me safe (wherever/whenever my car decides that it's not going to start again) - hopefully this isn't the pre-cursor to me driving down the road and it decides to stop running and I can't manage to safely steer it off the road.

AimeeJoy, I just got my recall on my ignition switch yesterday. Let me tell you what I did with the anti-theft system. Two years ago it was so bad that I was stranded so many times, and then when the light would go out, I would try to start it and it would happen again. One time I was stuck for over 60 minutes in my car, in the heat. I was searching on line and saw that people were spending a large amount money and it never fixed the problem, it would come back. There was this article, were this guy said to pop the radio out and cut the yellow wire that runs to the ignition. You have to leave the car running while you do this. We cut 2 different wires that were yellow and had to re-tape them because it wasn't the right one. That didn't hurt them at all as long as they are re-connected. The reason you leave it running is because when you get the right yellow wire and cut it the anit-theft light comes on and always stays on after that when the car is running. Let me tell you for 2 1/2 years it never happened again. You have to disable that anti-theft system. This really works and cost nothing. Hope this helps you.

Can't help you there, I'm sorry. The car has to be running when you cut the wire, because the anti-theft light will come on and stay on, and then you will know you cut the right wire. I don't know if you can find the right wire when it is not running. Even if it took an hour or so, my car would start finally. I have never had one problem with it since.

I discussed this with the Chevy dealership and they did inform me that they were aware of this issue but would not have a recall on this since it's not a life safety issue so we are screwed. The dealer stated they could reprogram the unit for $120.00 or turn the car to the on position for 10 minutes three times and then it should start and be reprogrammed, but for how long who knows. That's a bad deal when the manufacturer won't fix the problems. I'm in the process of purchasing a Toyota now so I'm going non American vehicles, never a Chevy again sorry America build a good vehicle and stand by it or loose business.

I swore I'd never by a Chevy but I got a good deal and I actually love my Malibu 2003, however that damn theft system is a pain. What I have learned is that it does no good to look at a clock. It takes about 11 minutes with car in start position for light to quit flashing. If you jump the gun or use the clock. I have to just wait until that light is solid and then it starts. Very annoying because I never know what might trigger it. It is very random. I have tried any number of remedies and it still does it when it damn well feels like it.
