SOURCE: anti-theft/security light on dash doesn't flash on 2005 avalanche

Several GM products, including the Chevrolet Impala and Malibu, the Oldsmobile Alero, the Pontiac Grand Prix, and Saturn Ion, have issues with the Security light coming on. This is many times an indication of a failing Body Control Module (BCM). Initially, the Security light will come on then go off, progressing to a constant on light, before the car will refuse to start. Other symptoms may include erratic action of electronics, a clicking sound coming from the glove box, and the air conditioning failing to blow cold air. I recommend a shop that specializes in the electronic systems of vehicles to diagnosis and make the necessary repairs. They should keep the car until they replicate the symptoms described. A new BCM from GM should cost about $230; plan on another $200 for them to diagnose the problem, replace the unit, and program the new unit. The dealers quote between $700 and $1,100 for the same repair. My experience and the experiences I have read on the internet, indicate the new BCM should last only about a year.

This an all too common problem on GM vehicles. Fortunately there are ways to beat this without taking to the dealer. Go to this link and try the quick fix. If that doesnt work you'll have two options, taking to the dealer to get things diagnosed and replaced, or bypass the system entirely. This link will help you.

Try using old key in doors to lock and unlock, and reset/disarm anti-theft. Start with drivers door first, then try passenger if that doesn't work.

2005 avalanche 5.6 LT Z71 at times will not start, well...starts but stops right away, when it starts none of the gauges work, windows, door locks, radio,air, they may or may not start working, sometimes...


This sounds like an "anti theft security" problem to me. Symptoms: Start and stop within 5 seconds or less. Random starting problems, good one day bad the next. SECURITY light illuminated on dash somewhere. (might not be lit due to the bypass that HAD to be done to install remote start) Read up on this link and compare symptoms.

Anti theft system came on dash. shut the car down will not start. 2002 cadillac. i was told 30 differ sensor showed wrong. which sensor to start with.


The SECURITY light is located on the instrument panel cluster.

If the ignition is off and any door is open, the SECURITY light will flash, reminding you to arm the system. To arm the system, do the following:
1. Open the door.
2. Lock the door using the power door lock switch with the door open or the remote keyless entry transmitter. The SECURITY light should come on and stay on.
3. Close all the doors. The SECURITY light should go off within approximately 30 seconds. If a door or a trunk is opened without a key or a remote keyless entry transmitter, the horn will sound and the lamps will flash for about 30 seconds.

Also can check this and other details in the 2002 Cadillac Owners Manual (page 85 and next).

Hope helps (remember rated and comment this).

'05 Chevy Malibu Wil Not Start


is the security light blinking on the dash? If so you need to rreprogram the key to the anti theft module. to do this, turn key to on...let sit for about 10 min or so until the security light flashes. turn key off.. count o 5. vehicle should start. if not then it will have to go to the dealer to have it specifically reprogrammed as the PCM and anti theft modules both no longer reconize the key code.
