Asked by nb2004 Oct 28, 2016 at 08:40 PM about the 2004 Chevrolet Classic

Question type: Maintenance & Repair

I have a 2004 Chevy Classic. I just bought it last year, 174,000 miles. The
first time the anti theft system malfunctioned I thought it was my fuel pump,
starter, or out of gas. I know nothing about cars! After noticing my blinking
theft system light, a quick googled search showed me how to reset the
system. (I used the-- turn key to "on" leave for 10 minutes until light stops
blinking, turn back to "off" position, then start. worked like a charm)
I've gotten used to running out to start my car 10 minutes before actually
having to leave. (this happens a lot!) Last weekend my theft system light
came on, but was not flashing and would just stay on. I tried the 10 minute
reset, the lock/ unlock, something about messing with the radio power
button. Nothing worked! I decided to let it be and took my husbands car.
After a few hours of not trying, my husband went out and started messing
with the power locks, and radio, put the key in the ignition and the damn
thing started right up!! Again today this happened. After spending 2 1/2
hours in the parking lot of work (tried disconnecting the battery, leaving it
for 15 minutes then hooking it back up) I had my husband make the 30
minute drive to pick me up.

Okay! after that long winded explanation I need to know how to get my car
started!! I'm fed up and just want to sell it! Any suggestions on anything I
haven't tried yet. I'm very confused as to why my light went from blinking
when this happened, to a solid light??

Js08016 and have them do what? I've been told a new fuel pump, new ignition switch, and multiple other pricey "fixes" I don't want to be mislead, as I know it has to do with the anti theft system.

I have the same trouble. Sad because it runs like a top. Having problem again. I did take it to the dealer and they said it would cost 1000 dollars to fix. I said the car wasn't worth that much. They said, " Well you would have to pay more to get a new car" which I thought was rude.

Same thing happened with my 2004 Impala! I found an answer on another thread and it fixed it. Find a company that installs stereos and after market security systems. Call to see which ones are familiar with installing a bypass device on the ignition. I called 2 local companies, but only one knew exactly what I needed. It took them, an hour to fix and $100. Never had any problems again!!! My daughter's 2004 Chevy Classic is doing it now so I'll have it done to hers as well. Oregon's prices are high so it wouldn't surprise me if you can get it done cheaper elsewhere.

Was told by the dealer, the chip in the key was somehow cleared. Even though you clear the anti-theft, the 'bad' key indicates to the internal computer 'theft' so it turns on again. Take to dealer, have them fix your key, or give new key. Resolved our problem when I did this. 'copy' keys from Lowes/Home Depot only work for a short time and then trigger theft again. Need chipped key.
