Question about 2006 Chevrolet Impala

4 Answers

Where is the Anti Theft Light on 2006 Chevy Impala?

April 9, 2015: Everyone is talking about a Light on or flashing indicating the Theft System is on and preventing Car from Cranking and Starting. My Computer Message Center flashed a Message saying "Service Theft Deterrent System" only once about a week ago. After trying several times I waited maybe 10 minutes and then car started. Now Car will not start again and for 3 days so far it has not cranked or started. But there has been no further Messages - and I do not see any Theft System Lights anywhere. Where should I be Looking for this Light? My car is a 2006 Chevy Impala LT (Fleet Car - as originally it was owned by HERTZ Rental Car Company). I have 139,000 miles on the 3.5 Liter V6 motor. I have tried Re-charging the Battery, Cleaning the Battery Connectors and Posts, and Jump Starting - but car will not crank, or start. My wife and I are both older and disabled and stuck at home and unable to go anywhere with car not starting.

Most of the cars from the 2005 on up have a chip in the ignition key and when the key is put into the ignition switch this then talks to the chip incorporated in the switch which sends a message to the pcm telling it that all systems are go and then allows the car to start. Usually the one chip that is connected to the ignition switch is the one that goes bad. You may end up at the dealer to get this fix. Hope this helps.

Testimonial: "Darrell Larsen: Thanks for your response - but that still doesn't tell me where the Light that is supposed to be "ON" or "Flashing" is Located at. That was my Question. Is it supposed to be someplace near the Speedometer? Is it to the right? To the Left? Above or at the top edge of something? Just where on the Dashboard is this light supposed to be? Or is it some kind of warning Symbol similar to the "Check Engine Light"??? I just need to know where this Light is supposed to be to see if mine is ON or OFF."

Hi, Your remote for the car should disable the security system, check that your remote has enough power to unlock the anti thief. Basically if you can lock and unlock the car your remote should be fine. That's the first check. the next thing to check is the fuse for the security system. if the fuse is blown you will get the problems you are having OK. So, check the fuses. I am thinking that the fact that the trouble light is not coming on is a good indication the fuse is blown. Check the fuses. If this doesn't work you are basically looking at having it towed to the dealer. Good Luck!

Testimonial: "Silas Lawrence: Thanks for your response. While your first comment is really getting down to basics about the Remote having enough battery power - your second comment regarding their possibly being a Fuse that is out for the Theft Deterrent System or Theft Deterrent System Warning Light is interesting. Now that brings up another question as where that Fuse might be? Also I would think that the Car Manufacturer would not have a Fuse where a Burglar or Thief could get to it and Disable the System. But I will spend some time looking for a Fuse. I wonder where the Theft Deterrent System Light is supposed to be though."

Simple answer, TAKE IT TO THE DEALER..... they need to reset some of the computer codes, nothing else will fix it



update
Curious as to why you are fixated on the anti theft light.... likely if it is an anti theft system issue, it could be the anti theft module, located under driver side dash just above left foot, black box with multiple blue and pink connecters, corroded connectors can also be an issue

Update
If you are doing the key on ign. off for ten min procedure, you need to do the whole procedure 3 times for full reset....

Testimonial: "Mark: I called the Service Department at Dealership. They tell me they will have to tear my Steering Column apart and look around. Sounded like they don't know what they are talking about. They would not even give me an estimate on how much it would be. Car would not start for 3 days in a row, then on the fourth day it started right up on the first turn of the Key. Local Service Repair Shops told me to turn the Ignition on and leave the Door open and let it sit for 10 minutes. Then after that turn the key off and then turn it back on and start the car. I haven't tried that yet - as I just said on the 4th day the car started on the first try. We drove around to different places but I was afraid to shut the car off - so my wife stayed in the car with the engine running while I went in various places. So we had the car running all day non-stop until we got back home and then I shut the car off. Today when I go out I will see if it starts again or not. Still do not know where this "LIGHT" is supposed to be at - because No one will answer my question. When I did open the driver's door to get in to start the car - the warning bells were chiming like they were saying I left the Key in the Ignition or something like that. But I hadn't - as I was just getting in the car. Then later at the end of the day when I shut the car off and pulled out the key - the warning bells started up again. So I put the key back in and out of the Ignition and the bells stopped."

I too am an elder. I also had an unusual issue with an older car that unfortunately did not have a locking gas cap. Anyway, I completely understand your frustration. The new security systems are so complex that long distance diagnosis is impossible. You may have seen on TV there are fairly simple compact devices that can overcome the car security systems. I would guess your car was "attacked" by such a device. I can only suggest your dealer or perhaps a very up to date Locksmith that can help you. If Locksmith I would call many before I made a decision. Perhaps you are fortunate enough to have AAA and they can make a suggestion. Or a similar service. I'm sorry I cannot offer better advice, but hope some of this helps.

Testimonial: "gbob59: Thank-you for your response - but for my case - my car was not attacked or hacked. My car has been having problems with the Computer in the car and the "Service Theft Deterrent System" Message appeared. This then stopped my car key from working and it will not start the car. So I am looking for a way to turn-off or re-set the Theft Deterrent System so that I can start my car again. My Posting was an Inquiry about the Theft Deterrent Light that everyone is talking about, as I do not see that on my 2006 Impala. So I was asking where is this light supposed to be at?"

Well How good are you at Resistors?? Get an Ohm meter and check the ohm's on your key, Next go to radio shack and buy a few Resistors that are the same Ohms and climb under the steering wheel.. You should see 2 Small thin wires Coming from the column, WARNING, There is a Second Yellow Wire With a Sticker on it Saying Air Bag, Don't touch...

When you fine the 2 small wires the DO NOT SAY AIRBAG Disconnect the plug and Add you Resistors to that plug leading away from the column,.

When you put key in the Light should go right out if the Ohms are correct... Not to mention you can now buy keys without chips for that car too... Good luck. AND stay AWAY from the Air bag, I would tell you have a Pro look at..

I need to know where exactly is the fuse that controls the security system in a hhr chevy 2006 is located in the panel. I do not have a owners manual.


Security system ? your vehicle has two ! Content theft and anti-theft that prevents drive away theft ! Is the Security Indicator lit on the instrument cluster ? If the light is on it's not a fuse issue . You need to take or have towed to dealer . Nothing your going to be able to do .
The security indicator on the instrument cluster is controlled by both the VTD System and the CTD System. The security indicator is controlled by the body control module (BCM) via a discrete output.

your anti theft device is activated,you need to lock and unlock your doors a couple times with the key fob,not the key,and then you need to put the key in the ignition and start it,if you dont have your key fob,call your car dealer to get a new one,they are programmed for each car only,you cannot bypass it.

1997 chevy malibu anti theft system how do I fix this problem The car won't start I believe the car is in the anti theft mode


The late-90's GM Passlock system (e.g. 1997 Malibu, Regal, Impala, etc.) has a part around the ignition tumbler that goes bad and no longer reliably detects the valid key. In that situation, the "Theft System" light will slowly flash and the carburetor is cut off so the engine won't start. The time-out on the system is 10 minutes - you don't have to do anything, you don't have to disconnect the battery, the key can be out of the ignition -- it's just a time delay. After 10 minutes, the light goes out and you can try again (but if the key is again not detected, the light will start flashing again and you have to wait another 10 minutes)
Someone else, who had this problem, told me to remove all other keys from my keyring. The weight of the other keys pulls on the ignition key causing the key to be unreadable. It has been 7 weeks since I have been doing this and have not had a problem

2005 Chevy Malibu Anti-theft system indicator light


I just had this to happen to me - here's what you do - when it will not crank - turn your key over to ACC and let it stay on here for 15 minutes, the THEFT SYSTEM light will stop flashing. Turn your key back to OFF then turn it over as normal when starting and it will start right back up! Found it out from an auto store! One lady paid over $700 and then found this out!!!
