Does the Security light blink intermittantly?
I am having a similar problem with my 02 Impala.
Another posting on this site suggests that the BCM and Ignition switch could be the root of the problem.
Chevy PASSLOCK/SECURTIY sucks!! The Impala BCM's are Junk!
I've had the BCM replaced on my 02 Impala when it only had 39K on it!!
I have 70k on my Impala and I suspect that I have the same problem again!! I guess that the BCM only works for 30-40k than you have to dump $400 to get the dealer to install a new one. Impalas are lemons!!

To all having a problem with the security light... call GM corporate and complain and ask to get a recall on this. Apparently recalls are initiated only after a lot of people complain. I called 1-800-222-1020 this morning to register my complaint.
My 2002 impala has been having the security light/not starting problem for probably 9 months now. We had been trying the wait 10-15 minutes with key in on position (to clear the codes), shut off, then turn on and had success most of the time. Finally took the car to the dealer today. They claim it is just the passlock sensor in the ignition cylinder but costs upwards of $400 to replace (just for the ignition cylinder. If it were the BCM, which they don't think it is - that would be $600-$800). Either way - save your receipt. If enough people complain and a recall is issued then the rest of us should be able to get reimbursed for this repair.
#22 of 447 Possible BCM problem

I have an 02 Impala. I suspect the Body Control Module is defective.
I had the blinking security light, noises under the dash and the airbag light would stay on.
I had the BCM replaced and everything was fine.
It seems like defective BCM's are a common problem for the 01-05 Impalas.
Plan on spending 350-400 dollars to have it replaced and programmed.
#23 of 447 BCM problem and reprograming - HELP!!!

I am having a similar issue as everyone else. '01 Impala has always had the airbag light on constantly, the blinkers go on the blitz but can be remedied with a quick jab at the flashers.
Then my power door locks went out a couple weeks ago and the Security light started coming on everytime we turned the car on and sometimes just randomly driving down the road. If we stopped, turned the car back off and on again, it would usually fix the problem.
Today we hopped in the car and headed down the road and about 100 feet from the house noticed none of the lights on the instrument cluster were on, actually it wasn't even working. So we pulled over to restart the car (that seems to help often) and when we went to start it up again, nothing. Dead. No turning over, no clicks, nothing.
Oh, and did I mention we are now living in Germany, where Impalas are as rare as a buffalo in NYC. Except for the MP cars, but they don't matter, because they are serviced completely my military personnel, which won't even bat an eyelash our way.
A kind American stopped by and told us to pull the battery cable, let the car set for 10 min and try to start it up again. That worked.
The nearest place that will even look at Impalas is about 3 hours from here.
After reading many posts here I realized we may be looking at the "FAULTY BCM" that is causing everyone stress. We found one online for about $15-$20. But if we replace it (somehow) does it still have to have some sorta factory programing done on it?
This wouldn't be so bad if we weren't in a country where people don't like to speak English and definitely don't like American made cars.

Could be a problem with the 4-way flasher switch. The turn signal flasher is built into this switch. If it malfunctions,the turn lights wont flash. GM has had problems with these switches. There is a recall on some of them.

Can you or anyone for that matter tell me how to replace it or is it something that has to be done by a mechanic?

Someone hit it right on the head. The 4 way flasher and the turn signal are the same unit.
IF you have an extended warr. or it is a recall they will do it for free.
Th relay craps out, the temporary fix is: if this happens while driving just tap the emergency flasher button and the signals will work again for a while.

Which relay is it, there are two DRL/EXIT LTS and EXT LTS. So if it's the relay how does tapping the emergency flasher fix a blown relay. I tried tapping it and it worked for a while, I didn't think a relay worked like that. Anyone else had this problem and fixed it?

It is not a relay you can fix. It is not a lone relay. The Turn signal module is the same module as the 4 ways; EMERGENCY FLASHERS.
This unit is mounted high in the dash board.
You know where your 4 way flashers are, right ..???
The relay does not fail, it just gets dirty or worn and it works sometimes when the directionals fail, if you tap or depress the 4 way flasher button.
To change this module yourself is a project, have Chevy change it. And fight with them, because this is something that should not fail in 4 years..!!
