The security system (VATS/PassKey) is having problems, it's typical on those trucks. You can find a great write-up here: http://newrockies.ca , it was the only thing that saved my Park Avenue.

SOURCE: wont start security light stays on

My girlfriend had the same problem, so we took it to the local dealer in Costa Mesa, CA and were told she needed a new engine to the tune of 5K. We decided to take it to our local mechanic and he discovered that the “ignition control box”, which apparently has the antitheft controls too and shuts the flow of gas to the engine because it thinks its being stolen when it malfunctions, was causing the starting problem. Once, the box was replaced it worked fine. Because the IBC controls antitheft, it will need to be “reprogrammed” be someone that has access to the proper equipment or the dealer. I think the whole thing was about $800 - $900. Sure beats $5,000

Hope this helps,
B

You need to reprogram the security system. Hook up a battery charger. Turn the key on, the security light should flash. Leave the key on until the light stops flahing.(11 minutes) Turn the key off for 20 sec. Turn the key on, do the same thing a second time, turn the key off. Turn the key on. Do this a third time. After the third 11 minutes and the light is off, Start the truck.

SOURCE: 02 yukon denali security light stays on will not

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.

Is the security light flashing? If so, turn ignition on and wait for 10 minutes and light should stay on solid. Then try and start the car without turning the ignition back off. Then turn off ignition and wait 1 minute. Then turn ignition on and see if security light is flashing. If not try and start your car. If it is flashing, try waiting again with just the ignition on and see if it goes out.

My security light stays on in my car


If it stays on and the car starts you are in bypass mode.
Some times remote starting alarms have a switch under the console to put a car in this bypass mode.

If not pull the battery for 5 min. and relearn your key.

If still no luck you are me and you got a code in a BCM or PCM.

Just from changing a battery.....Love GM....well in the 60s maybe
