I have 2002 Escalade. My security light keeps on flashing while I'm driving. But sometimes when I try to start my truck, it wont start. Like the computer is cutting the car off. But then it will eveually will start. And the security light is flashing. I looked to see if there is TSB and

01-00-89-009 MAY 01 Key/Key Number/Security Chip - Replacement (http://www.alldata.com/products/diy/index2.html)

So what do you think guys!!!!

That could be the problem, or it could be the resistor in the head of the key. Sounds like a dealership trip to me either way. Is it still under the 4 year/ 50,000 mile factory warranty?

Oh, and :welcome:

i had the same problem it was a wire that was loose of the alarm its the security alarm that already comes with the cadillac its not getting the whole signal and it thinks its not the key ur starting with it

If you have a Remote start in the vehicle that would be it.
I had a few vehicles with a Remote start and they all would do the exact same thing and that was the problem.

If you don't have a Remote start.. sorry.. not sure what it would be.
Good luck.

Guess it depends on your remote start installer. I've had one for 2+ years and 0 problems.

This happened to me last night. However, my security light is always flashing. I went to go jump in the truck last night and it wouldn't start. I had to be jumped inorder to get home and when I got home, it wouldn't start again. A day before, I turned on my aftermarket alarm and I believe it just discharged my battery. I left the my extra aftermarket alarm off like always and in the morning, my truck started perfectly fine and the battery had recharged itself. I believe there is a short in the aftermarket alarm electrical wiring, so i'm fixing that this weekend.

By the way, last night when it would just *click click click click* when I would attempt to start it, I could tell the battery was discharging faster and faster. I tried starting it remotely with my keys and everything in the car immediately went absoluetly crazy; lights were flickering, monitors were flickering, and the in dash/night lights were flickering as well. The front and rear alarm lights were flickering slower and slower as they died off. At one point, I heard the alarm system sound fade in and out within seconds. I was totally stunned by the whole situation. :banghead:

Well I had remote starter and I had it diconnected because I thought that was the problem. But now it doing it again. And I dont have the remote starter connected.
