The security light is a visual indication that something in the car's antitheft system is failing. In most GM cars and trucks there is a hidden system that most people are unaware even exists. From the moment you put your key in the ignition, there begins a constant line of communication between your key's security chip or transponder, to the ignition's lock cylinder, and then to the car's TDM. (Theft Deterrent Module) The TDM is what tells your computer that the correct key is being used and that it is "OK" to allow the vehicle to start and run. These 3 parts must be in CONSTANT communication. If the key is in the ignition, then these parts are sending important signals to each other. The security light illuminates when that signal gets broken, even just for a second. When the signal breaks, (normally due to a failing/broken part) the car goes into antitheft mode. The car misinterperates this and thinks its being stolen or hotwired because it is NOT getting that signal from YOUR specific key. There is where the security light turns on and shuts down your vehicle. So basically, if that light is on, your system has some sort of failing part. This can start as an intermittent "no start", to your vehicle not running for days at a time, to the vehicle NEVER starting again. The problem is electrical and computer based, so don't count on an easy reset button, or the problem fixing itself. The hard part is isolating which part is the problem. You can spend a thousand dollars through a mechanic very easily. I have had great luck with bypassing the entire system. This way the problem will never return. It actually CAN'T ever return because it is eliminated. This can also be done yourself at a much cheaper cost. Read through this link very carefully. You'll find alot of information and pictures, along with ways to help you fix this.

My door chime keeps going off in my 2003 Taurus. Can I pull a fuse to disable it or is there another option?


Is the door fully closed? If the chimes continues to chime I would check the door switch. Does the inerior light stay on longer than normal? If so the door switch could be bad and the safety circuit is cutting it off before the drains

Disable seatbelt chimes,will not go off, since driver door been replaced.


Sounds like the door switch is not switching or not connected. Sometimes the switch is external in the door jamb/closing area, sometimes it is part of the door catch. Maybe check if the door light on the dash stays on, also if the interior light works on door setting.

I have a 2009 Dodge Grand Caravan. As you drive along a chime starts going off. No lights on dashboard light up.


Be sure all doors are closed securely including rear hatch. If that still happens one of the door or rear hatch electrical switches may need to be adjusted. If the car has been struck lately, start looking in that area.

Reset passlock code


Is your Impala a 2000, 2001, or 2002? This seems to be a common problem in those model years...much like its predecessor the GM VATS (Vehicle Anti-Theft System). While the VATS had a permanent (albeit unapproved) solution, no suck workaround appears to be available for the Passlock system. Some websites offer a correction "module" that looks to be a hit-or-miss solution. I did find the following procedure on a forum, and it seems to be reliable. Here goes:
If your car has been sitting while you were at work or home or in the store, and you are coming out to leave, follow steps 1-6.

If you just had the SECURITY SYSTEM lock you out of the ignition system, you will have to wait the 10 minutes for it to reset and allow the ignition control module to interact with the system. Once the 10 minutes have passed from the ACTIVE SECURITY STATUS, follow steps 1-6. Do not try to shortcut this as it wont work.

If it is raining, you can close your door, just not all the way. Close it all the way and open the door latch without pushing the door open. This will keep you dry.

+++++STEPS+++++ 1.) OPEN YOUR DRIVERS DOOR AND SIT DOWN. 2.) PLACE KEY IN IGNITION, WAIT FOR CHIME. (3 seconds is what I usually wait) 3.) TURN IGNITION 1 CLICK RIGHT (TO THE ACC POSITION) AND STOP! Do not continue to ON and START yet. WAIT ATLEAST 5 SECONDS 4.) AFTER 5 seconds has passed, TURN KEY TO ON and STOP, DO NOT CONTINUE TO START YET! 5.) WAIT AND WATCH. With your drivers door open, here is what you will see and hear = Your notification will signal DOOR ADJAR, then the BATTERY light, then the SECURITY light, during which you will hear the chime sound as if you just started the car. 6.) AFTER YOU SEE THE SECURITY light switch back to DOOR ADJAR or Battery, and after the CHIME has stopped, you can turn the key to start and voila!

It has worked every time for me and 5 of my friends. This whole process takes about 20-30 seconds, but it sure as hell beats 30 minutes, as GM refuses to compensate my time lost to their vehicle\'s design flaws.

RECAP: 1.) Open driver door, sit down 2.) Insert key in ignition, wait for chime 3.) Once chime starts wait 3 seconds 4.) Turn key to ACC position WAIT atleast 5 seconds 5.) After 5 seconds turn key to the ON postion and wait for the security light to switch back to Battery or DOOR adjar, and the chime to stop (Do not try to START if the chime is still sounding) 6.) Once chime stops and Security light has passed, You may now complete the turn to START and it will start.

Note: This is not a permanent workaround, but it will buy you some time, I can almost guarantee it will work for most if not all people, almost all the time.

I have a BF 2006 Wagon, the door ajar light will not go out. all doors and tailgate are secure. The chime sounds quite often and always when right blinker is activated. The interior light also flashes in...


99% is one of the switches in one of the door jams has become faulty. The switch will be coverd by a rubber boot. You can remove the switches and test them with a multimeter to find the bad one.

The dash light indicates I have a door opened and a chime dings when I hit a bump. All the doors are closed.


Check the 2 contacts on the passenger sliding door. If the door is out of adjustment they will have poor contact and a bump will jar it and turn on the light and chime. Make sure the side door closes securely.

Door ajar light & chime go off while driving.


Could be as simple as enough body movement to trip one. Find the buttons on the door posts & put something on them like masking tape (few layers) where those buttons or levers touch the door, and see if that helps, then start removing it one door at a time. And/Or, push in on the doors with some force & see which one has the most movement, the one that does, may be your culprit.

98 VW Beetle-Door Ajar Chiming while driving


Your door lock module is bad. There are two ways to fix it. #1 is to replace the module. Various places online sell new ones for $160, while you can get them used for around $50. #2 is to replace the switch, which costs around $3-9, but then you have to remove the door lock module, remove the old switch, and mount/solder the new one in. You can also pull the door lock module and cut the wires going to the switch which will tell the door that it's always shut, and it will stop your dinging. That one's free, assuming you can get to the DLM.
